Clinical Significance:
Myasthenia gravis (MG) is an acquired disorder of neuromuscular transmission that is characterized by skeletal muscle weakness and fatigability on exertion that is exacerbated by repeated muscle activity.2-7 This autoimmune disease is caused by antibodies directed toward receptors embedded in the motor endplate of the neuromuscular junction. Progressive weakness of the ocular muscles manifesting as asymmetric ptosis and variable diplopia are the presenting symptoms in 60% of patients.5,7 Many patients progress to more generalized weakness of peripheral limb muscles and muscles required for body posture, including facial and neck muscles. Bulbar muscle weakness compromises speaking (dysarthria), chewing and swallowing (dysphagia) and respiratory muscle weakness can lead to a myasthenic crisis where patients need to be ventilated artificially.8 Clinical symptoms may be restricted to one muscle group, in particular the eye muscles (ocular MG), or may become generalized (generalized MG).5-8 Patients with MG frequently have thymic abnormalities (thymic hyperplasia or thymoma).9 Ten to 15 percent of patients with MG patients have thymoma, and up to 50% of thymoma patients develop MG.9 It is thought that the thymus plays a role in MG pathogenesis and these patients respond well to the surgical removal of the thymus gland.10 Neonatal MG can occur as a result of trans-placental transit of antibodies from an affected mother to the fetus, or in some cases, due to antibody to the fetal form of AChR.11-13 In the latter case, the mother may be unaffected. It should be noted that the AChR antibody assays employed by Labcorp contain a mixture of adult and embryonic AChRs allowing for the detection of autoantibodies to both proteins. In most cases affected babies are born with a diminished ability to suck and generalized hypotonia. Decrease in utero feta movement caused by MG can also result in arthrogryposis multiplex congenital, a condition where the neonate suffers from contractures in more than two joints and in multiple body areas. The majority of patients with MG have antibodies to the acetylcholine receptor (AChR) and, less frequently, to the other proteins at postsynaptic membrane of the neuromuscular junction.14-16 AChR antibodies impede neuromuscular transmission by a range of pathogenic mechanisms including the alteration of tissue architecture and/or by causing a reduction the density of functionality of AChRs.1,17-21 Three functionally different types of antibodies against muscle AChR can be measured.1,21-24 • AChR binding antibodies attach to the AChR activate the complement system result in in destruction and focal lysis of the neuromuscular junction leading to the destruction of AChR and AChR-related protein at the end-plate.1,20 • AChR blocking antibodies functionally block the binding of the neurotransmitter acetylcholine to the receptor.20 These antibodies usually occur in association with AChR-binding antibodies and have a higher prevalence in generalized MG compared with ocular MG.20 • AChR modulation antibodies crosslink receptor subunits in such as way as to cause the receptors to be internalized and degraded in a process known as antigenic modulation.20,22,25-27 Modulating antibodies are implicated with an increased risk of thymoma and the majority of patients with thymoma have modulating antibodies.28 Test for serum autoantibodies are highly sensitive and specific for generalized MG but lack sensitivity when there is pure ocular involvement.1,14,29-30 Approximately 85% of patients with generalized MG have detectable muscle AChR antibodies (of one or more types), while fewer patients with ocular MH have the antibodies (50-60%).4,30 In general, an elevated level of any one of the AChR-binding antibodies in a patient with compatible clinical features confirms the diagnosis of MG. Approximately 15 percent of individuals with confirmed myasthenia gravis have no measurable AChR binding, blocking, or modulating antibodies. Thirty-five percent of these patients (six percent of all MG patients) will have antibodies directed against a muscle-specific tyrosine kinase (MuSK).10,31 Autoantibodies levels do not generally correlate with disease severity. However, in individual patients, serial antibody titers tend to correlate with disease status.18,19,32-34 Autoantibodies directed against the contractile elements of striated muscle are found in 30% of adult patients with myasthenia gravis and in 80% of those with thymoma.35-37 Striational antibodies are associated with the late-onset MG subgroup and are rarely found in AChR antibody-negative MG.

Clinical Significance:
This test is set up in the Labcorp computer as a sequential series of tests to comply with customer needs and bill for testing that is performed. Smear, when appropriate, is a separate test along with appropriate specimen processing needed to perform the smear and culture. The culture portion of the test is also separate, and, once growth of acid-fast organisms (or other aerobic actinomycetales) is detected, the culture portion is reported and identification testing begins with PCR-based identification. The results of the PCR identification will be reported whether positive or negative. If negative, identification will proceed by MALDI-TOF and/or DNA sequencing. Biopsy or body fluid: Occult infections with nontuberculous mycobacteria, particularly Mycobacterium avium and Mycobacterium intracellulare, occur in patients with acquired immune deficiency syndrome (AIDS).7 In some institutions, the incidence of isolation of non-Mycobacterium tuberculosis species, specifically M. avium complex, may exceed the rate of isolation of M. tuberculosis. Mycobacteria have been recovered from culture of Kaposi sarcoma and bone marrow specimens in which the characteristic granulomatous reaction has been absent.8,9 Optimal isolation of mycobacteria from tissue is accomplished by processing as much tissue as possible for culture. Swabs should not be submitted. Tuberculous spondylitis represents 50% to 60% of all cases of skeletal tuberculosis. It is seen in children in developing countries and adults older than 50 years of age in the United States and Europe. Frequently, several vertebrae are involved and adjacent psoas muscle abscesses or paravertebral abscesses are not uncommon ("cold abscesses"). Colony counts obtained from bone biopsies are low; however, >90% are culture positive. The diagnosis of vertebral tuberculosis should be considered in all cases of unexplained spondylitis. Cases of sternal wound infection, early prosthetic valve endocarditis, infections complicating mammary augmentation surgery and other cutaneous/subcutaneous infections have been attributed to rapidly growing mycobacteria.10,11 M. fortuitum is the most commonly implicated Mycobacterium in these infections, which are thought to be caused by local environmental strains rather than contaminated commercial surgical materials or devices. Rapidly growing mycobacteria often grow on routine bacterial culture media within the time allotted to incubating routine bacterial cultures. Such organisms may be misidentified as "diphtheroids" and disregarded as contaminants. Pleural effusions frequently yield positive cultures in cases of pulmonary tuberculosis. The diagnosis of peritoneal tuberculosis is difficult and is usually made at laparotomy or after a considerable delay. Tuberculosis should be considered in any patient with ascitic fluid and chronic abdominal pain.12 Peritoneal tuberculosis accounted for 11% of a series of cases of extrapulmonary tuberculosis reported by Alvarez and McCabe.13 Pericardial tuberculosis accounts for <5% of extrapulmonary tuberculosis and frequently requires biopsy for diagnosis. See table.

Schedule:

-
Clinical Significance:
This test is used for detection and semiquantitation of serum IgG and IgM antibodies to Anaplasma phagocytophilum (HGE) to aid in the diagnosis of human granulocytic ehrlichiosis. Confirmation of diagnosis is based on laboratory testing, but antibiotic therapy should not be delayed in patients with a suggestive clinical presentation. The diagnosis of acute anaplasmosis cannot be confirmed solely by the presence of antibodies in a serum sample collected at a single timepoint. DNA PCR can be used to diagnose acute infection. Demonstration of a 4-fold rise in IgG-specific antibody titers by IFA in paired samples (acute and convalescent) confirms infection with A. phagocytophilum. IgM antibodies are less specific than IgG antibodies and are more likely to generate false positive results. IgM results alone should not be used for laboratory diagnosis. Antibody titers are frequently negative during the first 7-10 days of illness.

Clinical Significance:
For diagnosis and monitoring inflammatory activity in primary systemic small vessel vasculitides. The anti-PR3-ANCA Immunoassay is useful for confirming positive ANCA results by IFA, particularly with the cANCA pattern. Presence of anti-PR3 antibodies is highly specific for Wegener granulomatous (WG) disease, for which the sensitivity is reported to be 98%. Levels of anti-PR3 are elevated during active phases of disease and lower during remission. Monitoring anti-PR3 levels, therefore, can aid in disease management. The anti-MPO-ANCA Immunoassay is useful for confirming positive ANCA results by IFA, particularly with the P-ANCA pattern. Presence of anti-MPO antibodies is highly specific for idiopathic and vasculitis-associated crescentic glomerulonephritis, classic polyarteritis nodosa, Churg-Strauss syndrome, and polyangiitis overlap syndrome without renal involvement. Levels of anti-MPO are elevated during active phases of disease and lower during remission. Therefore, monitoring anti-MPO levels can aid in disease management.

Clinical Significance:
Antineutrophil cytoplasmic antibodies (ANCA) are a group of antibodies directed against cytoplasm antigens of neutrophilic granulocytes and monocytes. ANCA examinations are considered basic tests in immunological laboratories. The determination of ANCA is of great importance, in particular in the case of suspected acute vasculitis of small vessels, with severe pulmonary impairment or renal failure, but also in some non-vasculitis clinical syndromes such as inflammatory bowel diseases, e.g. ulcerative colitis. The most common target antigens of ANCA-associated vasculitis are proteinase 3 or myeloperoxidase. Antibodies against proteinase 3 (PR3) are referred to as c-ANCA fluorescent subtype, namely cytoplasmic antibodies (granular cytoplasmic fluorescence). PR3 is a neutral serine proteinase 3, also known as Wegener's autoantigen. Antibodies against PR3 are a highly specific marker in diagnosing Wegener's granulomatosis.

A discard tube is not required prior to collection of coagulation samples unless the sample is collected using a winged (butterfly) collection system. With a winged blood collection set a discard tube should be drawn first to account for the dead space of the tubing and prevent under-filling of the evacuated tube.4,5 When noncitrate tubes are collected for other tests, collect sterile and nonadditive (red-top) tubes prior to citrate (blue-top) tubes. Any tube containing an alternative anticoagulant should be collected after the blue-top tube. Gel-barrier tubes and serum tubes with clot initiators should also be collected after the citrate tubes.

Apo A-1 comprises 60% to 70% of the protein content of HDL. Apo A-1 serves as an activator of LCAT which is involved in the transport of cholesterol from peripheral tissues to the liver where it is degraded. Decreased serum HDL cholesterol levels have been reported to correlate with increased risk of coronary artery disease (CAD); however, Apo A-1 has been suggested as a better discrimination of CAD than HDL.1 Apo A-1 levels also correlate with survival rates or risk factors for patients with myocardial infarction and peripheral vascular disease. Measurement of Apo A-1 may also aid in the diagnosis of Tangier disease (absence of alpha-lipoprotein).

This enzyme has been identified as the rate controlling enzyme in cholesterol biosynthesis. Apo B may be important in the genesis of atherosclerosis and its quantitation useful in the evaluation of patients at risk for or having coronary atherosclerosis (CAD). High levels indicate increased risk for CAD.

-
Preferred Specimen:

-
Transport Container:
Jars of assorted size containing 10% buffered formalin
-
Collection Instruction:
Small biopsy specimens are to be placed immediately in 10% formalin solution. Use approximately 10 to 20 times as much formalin solution as the bulk of the tissue. Small tissues such as those from bronchoscopic biopsy, bladder biopsy, and endometrium can be compromised in a short time by placing in saline or allowing to dry. The following tissues should always be placed in formalin: small skin tumors and moles; uterine curettings; cervical biopsy; breast biopsy; prostate tissue from transurethral resection (TUR); bladder tumors and calculi; nerves and ganglia; rectal polyps; ear, nose, and throat (ENT) biopsy; lymph nodes (except those to be cultured); bone tumors; intervertebral disc; gallbladder; liver biopsy; bronchoscopic biopsy; fallopian tube segments; and any biopsy from any other site not listed. Organ and larger tissue resections are to be placed in larger containers and covered with adequate amounts of formalin. Specimens such as colons, urinary bladders, and uteri require opening to expose the mucosal surfaces to formalin. Gallbladders undergo rapid degeneration; therefore, they require immediate fixation in 10% formalin solution; an incision made in the gallbladder will aid in more rapid fixation. All specimens should be sent to the pathology department as soon as convenient to expedite the processing that leads to the eventual microscopic diagnosis.

Clinical Significance:
The principal use of C-peptide is in the evaluation of hypoglycemia. Patients with insulin-secreting neoplasms have high levels of both C-peptide and endogenous insulin; in contrast, patients with factitious hypoglycemia will have low C-peptide levels in the presence of elevated (exogenous) serum insulin. C-peptide is also useful in evaluating residual beta-cell function in insulin-dependent diabetics, many of whom have antibodies that interfere with insulin assays. Glucagon-stimulated C-peptide concentration has been shown to be a good discriminator between insulin-requiring and non−insulin-requiring diabetic patients. The diagnosis of islet cell tumor is supported by elevation of C-peptide when plasma glucose is low.

Clinical Significance:
Measurement of C-reactive protein aids in the evaluation of stress, trauma, infection, inflammation, surgery, and associated diseases as part of the body’s non-specific inflammatory response to infection or injury. Cardiac CRP assays are indicated for use as an aid in the identification and stratification of individuals at risk for future cardiovascular disease. When used in conjunction with traditional clinical laboratory evaluation of acute coronary syndromes, CRP may be useful as an independent marker of prognosis for recurrent events in patients with stable coronary disease or acute coronary syndrome. A prognostic value for measuring CRP has been suggested from studies with cardiac patients where elevated levels of CRP were associated with a higher risk of having a future cardiac event. Elevated levels of CRP have been associated with poor prognosis in cases of stable angina, unstable angina, and myocardial infarction.

Measurement of calcium is used in the diagnosis and treatment of parathyroid disease, a variety of bone diseases, chronic renal disease and tetany (intermittent muscular contractions or spasms). Although more than 99% of body calcium exists in bones and teeth, it is the calcium in blood which is of most concern clinically. The bones serve as a reservoir to maintain relative constancy of serum calcium by releasing calcium when required to prevent hypocalcemia and trapping calcium to prevent excessively high levels of serum calcium. The uptake and release of calcium from bone is under the control of parathyroid hormone.

Clinical Significance:
Monitoring serum carbamazepine concentrations, along with careful clinical assessment, is the most effective means of improving seizure control, reducing the risk of toxicity, and minimizing the need for additional anticonvulsant medication for the following reasons: •Serum carbamazepine concentrations correlate better with pharmacologic activity than does dosage. •Changes in carbamazepine’s half-life with prolonged treatment and interindividual differences in carbamazepine metabolism make it difficult to predict serum levels from the administered dosage, particularly during concomitant therapy with other anticonvulsants. Serum level monitoring helps physicians individualize dosage regimens.
•Carbamazepine is safe and effective only in a narrow range of serum concentrations. -

Clinical Significance:
Decreased in most instances of Wilson's disease (hepatolenticular degeneration); hence, ceruloplasmin is used in evaluation of chronic active hepatitis, cirrhosis, and other liver disease. In Wilson's disease, there is decreased ability to incorporate copper into apoceruloplasmin. As a result, free copper levels in plasma and in tissue, especially liver and brain, are greatly increased. Should be considered in cases of central nervous system disease of obscure etiology. Neurological symptoms include problems of coördination. Ceruloplasmin is low in Menkes kinky hair syndrome (In Menkes syndrome the defect is secondary to poor absorption and utilization of dietary copper.) and with protein loss such as the nephrotic syndromes, malabsorption, and with some cases of advanced liver disease in which decreases of serum proteins have occurred. Ceruloplasmin is high in a variety of neoplastic and inflammatory states, since it behaves as an acute phase reactant, although levels rise more slowly than “acute phase reactants.” Increases are described with carcinomas, leukemias, Hodgkin's disease, primary biliary cirrhosis, and with SLE and rheumatoid arthritis. High levels occur in pregnancy, with estrogens, and with oral contraceptive use when the agent contains estrogen as well as progesterone. Increased with copper intoxication.

MB can be used in estimation of infarct size. MB increases have been reported with entities that cause damage to the myocardium, such as myocarditis, some instances of cardiomyopathy, and with extensive rhabdomyolysis, Duchenne muscular dystrophy, malignant hyperthermia, polymyositis, dermatomyositis, mixed connective tissue disease, myoglobinemia, Rocky Mountain spotted fever, Reye syndrome, and rarely in rheumatoid arthritis with high titer RF.2 CK-MB does not generally abruptly rise and fall in such nonacute MI settings, as it does in acute myocardial infarct (AMI). • BB is rarely present. BB has been described as a marker for adenocarcinoma of the prostate, breast, ovary, colon, adenocarcinomas of gastrointestinal tract, and for small cell anaplastic carcinoma of lung. BB has been reported with severe shock and/or hypothermia, infarction of bowel,3 brain injury, stroke, as a genetic marker in some families with malignant pyrexia, and with MB in alcoholic myopathy.

After treatment with antibiotics, many patients develop gastrointestinal problems ranging from mild diarrhea to severe pseudomembranous colitis. This organism is an opportunistic anaerobic bacterium that grows in the intestine once the normal flora has been altered by the antibiotic. For diagnosis of toxigenic C. difficile, current practice guidelines from the CDC recommend confirmation by Nucleic Acid Amplification Testing (NAAT) if the glutamate dehydrogenase of C. difficile (GDH) Antigen is positive, and toxin is not detected by Enzyme immunoassay. Additionally, if toxin is detected without the presence of GDH antigen, confirmation by NAAT is also recommended.

Clinical Significance:
The diagnosis of Cushing syndrome (CS) requires evidence of cortisol hypersecretion. While serum cortisol levels fluctuate unpredictably and are strongly dependent on concurrent cortisol-binding globulin (CBG) levels, a 24-hour urine specimen integrates the cortisol production for an entire day and is not affected by CBG. Urinary cortisol reflects the portion of serum-free cortisol filtered by the kidney, and correlates well with cortisol secretion rate. The most common causes of CS are pituitary adenoma (65% to 70%), adrenal tumor (15% to 20%), and ectopic CS (10% to 15%).

Clinical Significance:
Abnormal changes in cortisol levels occur due to hypothalamic, pituitary, or adrenal malfunction. If undiagnosed and untreated, these disorders can lead to severe metabolic imbalance which may be life-threatening. The measurement of serum or plasma cortisol - utilizing morning and evening levels and/or stress tests such as ACTH stimulation or dexamethasone suppression - aids in the diagnosis of adrenal related disease. Excess cortisol levels are found in Cushing’s syndrome (adrenal cortical hyperfunction) while decreased levels are found in Addison’s Disease (adrenal cortical insufficiency).

Clinical Significance:
The mineralocorticoid receptor binds cortisol as an active ligand, yet in normal people cortisol levels are not related to sodium retention. While in vitro the mineralocorticoid receptor has a similar affinity as aldosterone and cortisol, and in vivo cortisol is found in concentrations 100 to 1000 times higher than those of aldosterone, 11β-hydroxysteroid dehydrogenase 2 protects the mineralocorticoid receptor by reducing cortisol to cortisone, which is not an active ligand. This enzyme occurs in cells that contain the receptor. A similar enzyme is present in other tissues but works more slowly and backwards, converting cortisone to cortisol. Defects in this system can cause hypertension and can be diagnosed from the cortisol to cortisone ratio.1-6 Apparent mineralocorticoid excess (AME) is a rare recessive genetic disease that is characterized by childhood onset of hypertension, hypokalemic alkalosis, and low plasma renin and aldosterone levels.7-8 Hypertension is caused by impaired conversion of cortisol to cortisone due to an inactive 11β-hydroxysteroid dehydrogenase (11βHSD). This condition may be diagnosed with elevated cortisol metabolite to cortisone metabolite ratios in urine or more recently with an elevated cortisol to cortisone ratio in serum.1 It is recommended that cortisol:cortisone ratios (F/E) be tested in hypokalemic hypertension cases where aldosterone, deoxycorticosterone, and renin are all low. Elevated cortisol:cortisone ratios may be found in chronic renal failure, excessive ingestion of glycyrrhetinic acid or derivatives, or in liver or bile-acid abnormalities.7 Even in these circumstances, however, determination of the cortisol:cortisone ratio is recommended to help shed light on the source of hypertension.

Clinical Significance:
Measurements of creatinine are used in the diagnosis and treatment of renal disease. Serum creatinine measurements prove useful in evaluation of kidney glomerular function and in monitoring renal dialysis. However, the serum level is not sensitive to early renal damage and responds more slowly than blood urea nitrogen (BUN) to hemodialysis during treatment of renal failure. Both serum creatinine and BUN are used to differentiate prerenal and postrenal (obstructive) azotemia. An increase in serum BUN without concomitant increase of serum creatinine is key to identifying prerenal azotemia. With postrenal azotemia, both serum BUN and creatinine rise, but the rise is disproportionately greater for BUN.

Some anaerobes will be killed by contact with molecular oxygen for only a few seconds. Overlying and adjacent areas must be carefully disinfected to eliminate contamination with indigenous flora. Ideally, pus or other fluid obtained by needle aspiration through intact skin or mucosal surface that has been cleaned with antiseptic should be collected. Sampling of open lesions is enhanced by deep aspiration using a sterile plastic catheter. Curettings of the base of an open lesion are optimal. If irrigation is necessary, nonbacteriostatic sterile normal saline may be used. Lower respiratory samples must be obtained by transtracheal percutaneous needle aspiration, transbronchial biopsy, transthoracic needle biopsy, or open lung biopsy by physicians trained in these procedures. If swabs must be used, collect two, use one for Gram stain and one for culture. Anaerobic transports must be used for swabs and for aspirates. Specimens are to be collected from a prepared site using sterile technique. Contamination with normal flora from skin, rectum, vaginal tract, or other body surfaces must be avoided.

Clinical Significance:
Monitoring serum digoxin concentrations, along with careful clinical assessment, is the most effective means of ensuring safe and effective therapy for several reasons: •Studies have shown a relationship between serum digoxin concentrations and clinical signs of toxicity. • Clinical manifestations of digoxin toxicity (cardiac disturbances, gastrointestinal problems, and central nervous system disorders) can mimic those of disease processes. • Concomitant use of other drugs, particularly quinidine, can markedly alter serum digoxin concentrations. • Digoxin has a narrow range of safe and effective concentrations in serum. Although the therapeutic and toxic concentrations overlap, measurement of digoxin levels helps to maintain effective concentrations and to diagnose and prevent overdosage.

Antibodies to dsDNA are associated with Systemic Lupus Erythematosus (SLE), in which immune complex formation is thought to play a major role in the pathogenesis of the disease. The deposition of immune complexes leads to inflammation and the renal and vascular characteristics of the disease. Sudden increases in SLE disease activity are generally preceded by a rise in anti-dsDNA levels, followed by a steep drop at the height of the disease. This observation confirms the necessity of monitoring the level of anti-dsDNA autoantibodies in SLE patients on a regular basis.

Clinical Significance:
Differential diagnosis of infectious mononucleosis. VCA IgG antibodies appear early in EBV infection and titers peak between 2-4 weeks after the appearance of symptoms. IgG levels decline slightly but persist for life. The presence of VCA IgG antibodies in healthy individuals indicates immunological exposure to EBV either as silent primary infection or past exposure. Because of the complex relationship that exists between the EBV virus/host reaction and clinical manifestation, tracking of EBV antibody patterns may assist in diagnosis of EBV infection. Individual levels of specific antibodies are not necessarily indicative of disease state but can be of diagnostic significance when tracked as an antibody response profile. Antibody response profiles for the different EBV antigens demonstrate a characteristic pattern for silent primary or persistent latent EBV infections, as well as for each of the EBV-associated disease.

Clinical Significance:
This test is used for detection and semiquantitation of serum IgG and IgM antibodies to Ehrlichia chaffeensis to aid in the diagnosis of human monocytic ehrlichiosis (HME). Confirmation of diagnosis is based on laboratory testing, but antibiotic therapy should not be delayed in patients with a suggestive clinical presentation. The diagnosis of acute ehrlichiosis cannot be confirmed solely by the presence of antibodies in a serum sample collected at a single timepoint. DNA PCR can be used to diagnose acute infection. Demonstration of a 4-fold rise in IgG-specific antibody titers by IFA in paired samples (acute and convalescent) confirms infection with E. chaffeensis. IgM antibodies are less specific than IgG antibodies and are more likely to generate false positive results. IgM results alone should not be used for laboratory diagnosis. Antibody titers are frequently negative during the first 7-10 days of illness.

Folate deficiency can be caused by insufficient dietary intake, malabsorption or excessive folate utilization. Excessive utilization occurs very commonly during pregnancy. Alcoholism, hepatitis, or other liver-damaging diseases can also cause excessive folate utilization. Folate levels in both serum and red blood cells are used to assess folate status. The serum folate level is an indicator of recent folate intake. Red blood cell (RBC) folate is the best indicator of long term folate stores. A low RBC folate value can indicate a prolonged folate deciency.

Clinical Significance:
Human LH and FSH levels are commonly determined in investigations of menstrual, fertility, and pubertal developmental disorders such as premature ovarian failure, menopause, ovulatory disorders and pituitary failure. The ratio of hLH/hFSH has been used to assist in the diagnosis of polycystic ovary disease. Low levels of hLH and hFSH may indicate pituitary failure while elevated hLH and hFSH levels along with decreased levels of gonadal steroids may indicate gonadal failure (menopause, ovariectomy, premature ovarian syndrome, Turner’s Syndrome). Low gonadotropin levels are usually observed in females taking oral steroid-based contraceptives. In the male, elevated hFSH and hLH with low levels of gonadal steroids may indicate testicular failure or anorchia. In Klinefelter’s syndrome hFSH may be elevated due to Sertoli cell failure.

Body fluid, aspirates: Aspirated material in sterile container.
Eye: For keratitis, scrapings with a Kimura spatula directly inoculated using “C” streaks are best.
Skin: Cleanse the area with 70% alcohol and collect a portion from the active border of the lesion.
Nails: For all types of onychomycosis, clean the nail area well with 70% alcohol, then, depending on type of nail disease, collect the following:
• Distal subungual: Clip the abnormal nail as close to the proximal edge as possible. Scrape the nail bed and underside of nail plate with a curet. Discard the outermost debris, which likely contains contaminants. Nail clippings are less desirable for culture.
• Proximal subungual: Pare down the normal surface of nail plate in the area of the lunula. Collect white material from the deeper portion of plate.
• White superficial: Scrape the white spots, discarding the outermost surface, which likely contains contaminants. Collect the white areas directly underneath.
• Candida infection: Collect material closest to the proximal and lateral nail edges.
Hair: Epilate 10 to 12 hairs and place them in a sterile container.
Stool: Random sample in sterile container.
Swabs: Throat, nose, nasopharynx, and ear swabs are acceptable; material from the ear is better than a swab.
Urine: Clean catch midstream sample in sterile container.
Wound: Aspirate of purulent material or fluid, scraping of lesion border, or swab (least preferred) in sterile container. Swabs cannot be split for other tests.
Avoid contamination of the specimen with commensal organisms as much as possible. Specify the source of the specimen and include any pertinent clinical information. Cultures are incubated one to four weeks (depending on source) before a final negative report is issued.

Preferred Specimen:

-
Collection Instruction:
Fecal specimens for parasitic examination should be collected before initiation of antidiarrheal therapy or antiparasitic therapy. The highest yield on hospitalized patients occurs when diarrhea is present on admission or within 72 hours of admission. The onset of diarrhea more than 72 hours after admission is usually caused by Clostridium difficile toxin rather than parasites or the usual stool pathogens. The following recommendations are made for efficient and cost-effective diagnosis of diarrheal disease in patients admitted with gastroenteritis.
• Submit one or two specimens per diarrheal illness immediately. Consider first requesting the EIA for Giardia and Cryptosporidium (see test Cryptosporidium, Direct Detection EIA [183020] or panel Giardia lamblia, Direct Detection EIA and Cryptosporidium, Direct Detection EIA [183558]. Giardia and Cryptosporidium are the most common causes of parasitic gastroenteritis in the United States.
• If EIAs are negative, request add-on testing for Ova and Parasites Examination [008623] and submit an additional stool specimen after five days for O&P examination.
• Also consider testing for unusual stool pathogens (Cyclospora Smear, Stool [183145]), especially in the immunocompromised patient.

Decreased to absent levels occur more with intravascular than extravascular hemolysis: haptoglobin binds hemoglobin, and carries it to the reticuloendothelial system. Thus, haptoglobin is useful in work-up for hemolytic states. It is low in the megaloblastic anemias, which have a hemolytic component. It is decreased in infectious mononucleosis. Decreases can occur with hematoma or tissue hemorrhage. Haptoglobin can be low with liver disease. Congenital absence occurs (small fraction of certain ethnic populations have ahaptoglobinemia, absence of detectable haptoglobin). Frequently elevated as an acute phase reactant, in inflammatory disorders (eg, collagen diseases, infections, tissue destruction, and with advanced malignant neoplasms).1

Hemoglobin A1C measurements are used in the clinical management of diabetes to assess the long-term efficacy of diabetic control. Diabetes causes elevated levels of glucose to circulate in the blood. Maintaining normal levels of blood glucose is part of the routine management of diabetics. Continuous and careful management of blood glucose levels prevents development of serious long term complications resulting from vascular impairment such as retinopathy, nephropathy, and neuropathy. Although a fasting blood glucose measurement gives the clinician information about the patient’s status over the last twelve hours, the stable HbA1C offers a more accurate indication of the patient’s long-term diabetic control over the last two to three months.

Clinical Significance:
This assay is used to detect total antibodies (IgG and IgM) against Hepatitis A virus (HAV) and may be helpful when assessing HAV immunity. The detection of total antibodies cannot differentiate between vaccination, previously resolved infection, or active infection. If active hepatitis A infection is suspected, HAV IgM testing should be performed. Hepatitis A is a vaccine-preventable disease of the liver caused by the Hepatitis A virus (HAV). HAV is transmitted via the fecal-oral route, usually from direct person-to-person contact or consumption of contaminated food or water. Hepatitis A is an acute, self-limited disease that does not result in chronic infection. HAV IgG antibodies produced in response to vaccination and/or HAV infection persist for life and protect against reinfection.

-
Transport Temperature:
Refrigerated
-
Stability:
Room temperature: 8 hours Refrigerated: 48 hours Freeze for longer stability.
-
Schedule:
1-2 DAYS
-
Clinical Significance:
Appearance of anti-hepatitis A IgM antibodies in the circulation demonstrates a recent exposure to HAV. Anti-HAV IgM antibodies appear a few days after infection and persist at elevated levels in the bloodstream for a few months. Detection of anti-HAV IgM does not necessarily imply an acute HAV infection due to the longevity of anti-HAV IgM. The detection of anti-HAV IgM can be useful for the differential diagnosis of hepatitis A from other forms of viral hepatitis. Any diagnosis should take into consideration the patient’s clinical history and symptoms, as well as other laboratory data.Patients with specimens exhibiting borderline results should be re-tested at approximately two week intervals. These patients may be at the beginning or the end of the acute infection. Testing for anti-HAV IgM at two week intervals will distinguish between early acute or a recovering individual. Rapid rise is associated with an early acute infection. Gradual decrease or a steady level of antibody is normally associated with late acute stage of infection.

Anti-HBc antibody determinations can be used as an indicator of current or past HBV infection. Anti-HBc antibodies are found in serum shortly after the appearance of hepatitis B surface antigen (HBsAg) in acute HBV infections. They will persist after the disappearance of HBsAg and before the appearance of detectable antibody to HBsAg (anti-HBs). The presence of anti-HBc antibodies does not differentiate between acute or chronic hepatitis B infection.

Herpes simplex virus (HSV) infects neonates, children and adults. Transmission can result from direct contact with infected secretions from either a symptomatic or asymptomatic host. HSV has been characterized into 2 distinct serotypes: HSV-1 and HSV-2. HSV-1 is generally associated with infection in the tongue, mouth, lips, pharynx and eyes, whereas HSV-2 is primarily associated with genital and neonate infection. As with other serological tests, negative results do not rule out the diagnosis of herpes simplex disease. The time required to seroconvert following primary infection varies with the individual, the specimen many have been drawn prior to the appearance of detectable antibodies. There are reports of sero-reversion. When appropriate, e.g., in suspected early herpes simplex disease, the test should be repeated or tested with a different assay. If on re-testing, the result remains negative, then a second sample should be drawn 4-12 weeks later and testing repeated. A single positive result only indicates previous immunologic exposure; level of antibody response or class of antibody response may not be used to determine active infection or disease stage.

Clinical Significance:
Immunodiffusion test is used to detect antibodies to Histoplasma capsulatum. The antigen used is a culture filtrate. Histoplasmin H and M preciptins can be identified by the assay. The M band often appears first and may occur without the H band. M preciptin is found in about 70% of both acute and chronic histoplasmosis cases. Both M and H occur together in only about 10% of patients. Results should be interpreted in the context of clinical presentation and other laboratory findings (e.g., fungal culture).

Homocysteine is a by-product of protein metabolism. In small amounts, homocysteine is not harmful to the body or blood vessels, but when an excess amounts accumulate in the blood stream, arterial vessels may be damaged and the resulting inflammation may eventually cause blockage of blood to the heart. Recent evidence has also implicated elevated blood levels of homocysteine as a strong independent risk factor for developing various forms of dementia, including Alzheimer’s disease. Increased homocysteine levels is associated with an increased risk of pregnancy complications (preeclampsia, early pregnancy loss, premature delivery, low birth weight, placental abruption or infarction, and birth defects such as neural tube defects, orofacial clefts, club foot, and Down’s Syndrome.

Clinical Significance:
The detection of anti-HHV-6 IgM or a fourfold rise in anti-HHV-6 IgG supports a clinical diagnosis of HHV-6 infection. Human IgM antibodies to HHV-6 antigens are detected by indirect fluorescent antibody (IFA) assay. Diluted serum is incubated on a slide containing infected T-lymphoblasts. If specific HHV-6 antibodies are present, they remain bound, are then labeled by an antibody conjugate and finally detected by fluorescence microscopy. Human Herpesvirus-6 (HHV-6) is a distinct herpes virus that typically causes a self-limiting illness in patients who are not immunocompromised. In some patients, especially if immunocompromised, HHV-6 can cause febrile convulsions in infants, encephalitis mononucleosis-like symptoms, and hepatitis.

Clinical Significance:
Type 1 diabetes, commonly referred to as insulin-dependent diabetes (IDDM), is caused by pancreatic beta-cell destruction that leads to an absolute insulin deficiency.1 The clinical onset of diabetes does not occur until 80% to 90% of these cells have been destroyed. Prior to clinical onset, type 1 diabetes is often characterized by circulating autoantibodies against a variety of islet cell antigens, including glutamic acid decarboxylase (GAD), tyrosine phosphatase (IA2), and insulin.2-5 The autoimmune destruction of the insulin-producing pancreatic beta cells is thought to be the primary cause of type 1 diabetes. The presence of these autoantibodies provides early evidence of autoimmune disease activity, and their measurement can be useful in assisting the physician with the prediction, diagnosis, and management of patients with diabetes. Insulin is the only beta-cell specific autoantigen thus far identified.4-6 Antibodies to insulin are found predominantly, though not exclusively, in young children developing type 1 diabetes. In insulin-naive (untreated) patients, the prevalence of antibodies to insulin is almost 100% in very young individuals and almost absent in adult onset of type 1 diabetes. Because the risk of diabetes is increased with the presence of each additional autoantibody marker, the positive predictive value of insulin antibody measurement is increased when measured in conjunction with antibodies to GAD and IA-2.2-4

Clinical Significance:
The insulin-like growth factor (IGF) system plays a critical role in the growth and differentiation of normal and malignant cells. The components of the IGF system include growth hormone (GH), IGF-I and II, type I and II receptors, IGF binding proteins and proteases. IGF binding proteins were first identified for their high affinity interactions with IGF-I and IGF-II.2 IGFBP-3 is the most abundant IGFBP species in circulation and binds 75% to 90% of circulating IGF-I in a ternary complex consisting of IGFBP-3, IGF-I and acid-labile subunit (ALS). IGFBP-3 modulates the activity of IGF-1 and to increase their half lives. It has been postulated that IGFBP-3 is regulated by GH and originates in the liver as low levels were observed in patients with impaired hepatic function.3 IGFBP-3 has historically been used in the investigation of growth hormone deficiency, acromegaly, hypopituitarism and to monitor recombinant GH therapy.4,5 IGFBP-3 is known to modulate the actions of IGFs in circulation as and at the IGF-1 receptor.3 IGFBP-3 has also been shown to exhibit distinct biological effects independent of the IGF/IGF-1 receptor axis.6,7 Recent studies have impaired interaction of IGFBP-3 with a variety of proteins or signaling cascades critical to cell cycle control and apoptosis; however, the actual mechanism of IGFBP-3 action is unclear.6

Clinical Significance:
Intrinsic factor is a glycoprotein (produced by the parietal cells of the stomach) that is required for the absorption of vitamin B12 from the diet.1 During digestion, stomach acids dissociate B12 from food and intrinsic factor binds to it and allows it to be absorbed in the small intestine. Conditions that impair intrinsic factor production lead to B12 malabsorption and deficiency. Laboratory findings for B12 deficiency include decreased serum B12 levels, increased methylmalonic acid and megaloblastic anemia.2-6 Impaired hemoglobin synthesis associated with B12 deficiency is characterized by abnormal maturation of erythrocyte precursors in the bone marrow, which results in the presence of megaloblasts with hypersegmented neutrophils and decreased erythrocyte survival.4 Vitamin B12 deficiency is also associated with neurological abnormalities.5,6 A leading cause of vitamin B12 deficiency is pernicious anemia (PA) caused by intrinsic factor deficiency.7-10 The condition is referred to as "pernicious" because it is clinically silent initially and only becomes manifest when patients experience generalized symptoms, such as weakness, diminished energy and (less commonly) dyspepsia.9,11 The incidence of PA increases with age and is relatively rare in individuals younger than 30 years of age.10 The highest prevalence is seen in Northern Europeans, although PA has been reported in virtually every ethnic group.10 PA can be caused by pathologic conditions that damage or remove a portion of the stomach's parietal cells, including bariatric surgery, gastric tumors, gastric ulcers, and excessive consumption of alcohol. Autoimmune ABG is caused by CD4 T cell-mediated autoimmune response directed against the gastric H/K-ATPase.11 Diagnosis of autoimmune PA relies on histologically proven atrophic body gastritis, megaloblastic anemia, B12 deficiency, and antibodies to intrinsic factor and to gastric parietal cells.10 Antiparietal cell antibodies are found in 90% of patients with PA, but have low specificity and are seen in atrophic gastritis without megaloblastic anemia as well as in various autoimmune disorders.10 Anti-intrinsic factor antibodies are less sensitive, being found in only 60% of patients with PA, but they are considered highly specific for PA.9,11-13 Laboratory diagnosis is further supported by increased levels of fasting gastrin and decreased levels of pepsinogen I.7,9 Epidemiological evidence and genetic studies suggest that PA has a significant heritable component and leucocyte antigen-DR genotypes suggest a role for genetic susceptibility.9,13,14 Long-standing Helicobacter pylori infection may play a predisposing role in many patients in whom the active infectious process has been gradually supplanted by an autoimmune disease that terminates in a burned-out infection and the irreversible destruction of the gastric body mucosa.9 PA is frequently associated with autoimmune thyroid disease (40%) and other autoimmune disorders, such as diabetes mellitus (10%), as part of the autoimmune polyendocrine syndrome.8,9 PA incidence is also increased in patients with primary biliary cirrhosis compared to controls.15 Autoimmune gastritis may predispose to gastric carcinoid tumors or adenocarcinomas.8

Clinical Significance:
Lactate dehydrogenase (LD) is an enzyme that is found in almost all of the body's cells, but only a small amount of it is usually detectable in the blood. LD is released from the cells into the bloodstream when cells are damaged or destroyed. Because of this, the LD test can be used as a general marker of injury to cells. Although there is some overlap, each of the five LD isoenzymes tends to be concentrated in specific body tissues. In general, the isoenzyme locations are as follows: • LD1: Heart, red blood cells, kidney • LD2: Heart, red blood cells, kidney (lesser amounts than LD1) • LD3: Lungs and other tissues • LD4: White blood cells, lymph nodes, muscle, liver (lesser amounts than LD5) • LD5: Liver, skeletal muscle Changes of LD isoenzymes periodically measured following onset of chest pain, studying the relationships of the anodic fractions, provide important information for the differential diagnosis of acute infarct of myocardium. The differential diagnosis of certain other diseases is enhanced as well with the use of LD isoenzymes. Useful in the differential diagnosis of acute myocardial infarction, megaloblastic anemia (folate deficiency, pernicious anemia), hemolytic anemia, and very occasionally renal infarct. These entities are characterized by LD1 increases, often with LD1:LD2 inversion. The isomorphic pattern (total LD significantly high with no increase in percentage, of any fraction) is seen with neoplasia, cardiorespiratory diseases, hypothyroidism, infectious mononucleosis, and other inflammatory states, uremia, and necrosis. LD5 increases are seen with striated muscle lesions (eg, trauma) and with liver diseases (eg, hepatic congestion, congestive heart failure, hepatitis, cirrhosis, alcoholism). LD5 increase is probably more significant when the LD5:LD4 ratio is increased. Although a modicum of controversy exists regarding the most suitable criteria for LD isoenzymes for the diagnosis of acute myocardial infarction, almost all laboratories recognize abnormality when LD1 equals or is greater than LD2. Alternatives to LD1 greater than LD2 have been proposed. Using an electrophoretic method (Helena), Rotenberg et al suggested the criterion of LD1 >90 units/L.1 A 1988 study examines application of LD1:LD4 and other ratios and finds that the LD1:LD4 ratio optimizes earlier and is the most powerful diagnostic ratio for acute myocardial infarction.2 A few percent of normal individuals may have LD1:LD2 ratios as high as 0.81. A ratio of 0.82−0.99 is suspicious of myocardial injury. A ratio >1.0 is diagnostic of myocardial injury, if other clinical criteria are met. In unstable angina, an increase of the LD1:LD2 ratio is described with normal total LD;3 however, progressively increasing LD1:LD2 ratio without complete inversion may have diagnostic significance for acute myocardial infarct.4 Persistent LD1:LD2 flip following acute myocardial infarct may represent a marker for reinfarction.5 Especially when acute myocardial infarction is complicated by shock, the isomorphic pattern may be found.6 LD1:LD2 inversion commonly appears subsequent to the isomorphic pattern in instances of acute myocardial infarction.7 The appearance of an LD “flip” (when LD1 is greater than LD2) is extremely helpful in diagnosis of MI. The presence of a LD “flip” a day following or with the detection of CK-MB is essentially diagnostic of MI, if baseline cardiac enzymes/isoenzymes are normal and if rises and falls are as anticipated for the diagnosis of acute MI. While CK-MB peaks 12 to 24 hours after onset of infarction, LD isoenzymes usually become diagnostic at about 36 to 55 hours after onset and return to normal between 3 and 14 days after onset.

The ratio of hLH/hFSH has been used to assist in the diagnosis of polycystic ovary disease. Low concentrations of hLH and hFSH may indicate pituitary failure while elevated concentrations of hLH and hFSH along with decreased concentrations of gonadal steroids may indicate gonadal failure (menopause, ovariectomy, premature ovarian syndrome, Turners Syndrome). Low concentrations of gonadotropin are usually observed in females taking oral steroid based contraceptives. In the male, elevated hLH and hFSH with low concentrations of gonadal steroids may indicate testicular failure or anorchia. In Klinefelter’s syndrome hLH may be elevated due to Sertoli cell failure.

Magnesium excretion controls magnesium balance.1 Magnesium urinary excretion is enhanced by increasing blood alcohol levels, diuretics, Bartter syndrome, corticosteroids, cis-platinum therapy and aldosterone. Renal magnesium wasting occurs in renal transplant recipients who are on cyclosporine and prednisone.2 Renal conservation of magnesium is diminished by hypercalciuria, salt-losing conditions, and the syndrome of inappropriate secretion of antidiuretic hormone.1 Magnesium deficiency is often inadequately documented by serum magnesium levels. Urinary magnesium analyses have been advocated before and after therapeutic magnesium administration to further investigate the significance of an apparent low serum magnesium.3

Collection Instruction:
Collect whole blood using venipuncture techniques. Gently mix the blood with the anticoagulant by inverting sample tube several times (do not shake).
Place freshly collected blood samples on ice or in a refrigerator 2°C to 8°C immediately, and store them at 2°C to 8°C until separation. Plasma should be physically separated from cells within two hours of collection by centrifugation at 2°C to 8°C. If a refrigerated centrifuge is not available, chill the centrifuge carrier in the refrigerator before use until cold.
Special precaution needs to be taken to ensure transfer of the plasma layer to a polypropylene (not glass) tube while avoiding carryover of any red blood cells or buffy coat white cells. The plasma samples thus prepared may be refrigerated at 2°C to 8°C for five days.
If plasma samples are prepared by gel based vacuum tubes, the plasma samples need to be transferred to separated tubes from the top of the gels immediately after the centrifugation.
Increased levels of MPO may be observed if the plasma samples are left on the top of the gels for more than eight hours before transferring to separate tubes.

Clinical Significance:
Monitoring serum phenobarbital concentrations, along with careful clinical assessment, is the most effective means of improving seizure control, reducing the risk of toxicity, and minimizing the need for additional anticonvulsant medication for the following reasons: •Serum phenobarbital concentrations correlate better with concentration in the brain than does dosage once steady state is reached. •Patients taking the same dosage of phenobarbital show considerable variation in serum phenobarbital concentrations because of individual differences in absorption, metabolism, disease states, and compliance. Serum level monitoring helps physicians individualize dosage regimens.

Clinical Significance:
This deoxybarbiturate is closely related chemically to the barbiturates. It is converted to two active metabolites, phenobarbital and phenylethylmalonamide (PEMA). Primidone is used principally in generalized tonic-clonic and complex and simple partial seizures; some clinicians believe that the drug has specific usefulness for complex partial seizures. It is as effective as carbamazepine or phenytoin in controlling partial or generalized tonic-clonic seizures, although a greater incidence of adverse reactions, especially during initial therapy, limits patient acceptance. Primidone is commonly given with phenytoin but monotherapy is preferred. The conversion of primidone to phenobarbital is significantly increased when this drug is used with other antiepileptic medication. It is not effective in absence seizures.

Clinical Significance:
Progesterone levels are indicative of viable pregnancies. Ultrasonography is required to confirm viability at low progesterone levels. Serum concentrations are relatively constant at 8-10 weeks gestation, unless the pregnancy is failing, which can be signaled by decreasing progesterone values. After 10-12 weeks, levels increase more rapidly, but serum progesterone determinations are not considered useful for diagnoses in late pregnancy. Ovulation, and the presence of a functioning corpus luteum, can be demonstrated with serial determinations of serum progesterone. Luteal phase dysfunction may be diagnosed when ovulation has occurred and there is inadequate luteinization and reduced progesterone secretion.

Collection Instruction:
Citrated plasma samples should be collected by double centrifugation. Blood should be collected in a blue-top tube containing 3.2% buffered sodium citrate.1 Evacuated collection tubes must be filled to completion to ensure a proper blood to anticoagulant ratio.2,3 The sample should be mixed immediately by gentle inversion at least six times to ensure adequate mixing of the anticoagulant with the blood. A discard tube is not required prior to collection of coagulation samples, except when using a winged blood collection device (ie, “butterfly”), in which case a discard tube should be used.4,5 When noncitrate tubes are collected for other tests, collect sterile and nonadditive (red-top) tubes prior to citrate (blue-top) tubes. Any tube containing an alternate anticoagulant should be collected after the blue-top tube. Gel-barrier tubes and serum tubes with clot initiators should also be collected after the citrate tubes. Centrifuge for 10 minutes and carefully remove 2/3 of the plasma using a plastic transfer pipette, being careful not to disturb the cells. Deliver to a plastic transport tube, cap, and recentrifuge for 10 minutes. Use a second plastic pipette to remove the plasma, staying clear of the platelets at the bottom of the tube. Transfer the plasma into a Labcorp PP transpak frozen purple tube with screw cap (Labcorp No. 49482). Freeze immediately and maintain frozen until tested.

A high altitude kit is also available for locations between 3350 and 6150 feet; a cap with a yellow ring differentiates the tubes.
-
Collection Instruction:
ONLY TO BE COLLECTED MONDAY-THURSDAY. Blood collection tubes should be at room temperature at the time of collection. Refer to collection instructions included with draw kit. Special specimen collection kit contains four gel-barrier tubes as noted above. All four tubes are required for a single test result. Each tube is designed to draw only 1 mL and fill time may be longer than other blood collection tubes. Because of the limited vacuum in these tubes, use a needle and holder (not a butterfly) to collect QuantiFERON® specimens. If a butterfly is required, first collect other required tubes or use another Vacutainer® tube to purge the butterfly line of air and then proceed with drawing the QuantiFERON tubes. Fill tubes to the black fill line on the tube. If tubes are underfilled or overfilled (see kit insert), immediately collect a replacement tube. Following proper fill, label the tubes appropriately and shake tubes 10 times firmly enough to ensure the entire surface of the tube is coated with blood cells to solubilize the antigen on the tube walls. After shaking, the volume may fall below the fill line. Do not centrifuge or refrigerate specimens. Return each of the four properly filled, labeled, and shaken tubes to the box labeled “QFT kit.” Seal the top by removing tape from the adhesive.
-
Transport Temperature:
Before incubation at 37°C, maintain specimen at room temperature. Stability: Kit must be incubated within 16 hours of collection. After incubation, maintain specimen at room temperature (17°C to 27°C). Do not centrifuge, refrigerate, or ship tubes on ice.

Infections in utero, particularly during the first four months of pregnancy, can lead to can lead to congenital defects such as deafness, cardiac problems, cataracts or glaucoma, and sometimes fetal death. Demonstration of rubella IgG antibody in a pregnant woman prior to conception provides assurance of fetal protection from possible rubella viral infection during pregnancy. Vaccination efficiency is demonstrated by detection of rubella IgG antibody in serum following immunization.

Clinical Significance:
This test is used to aid in the determination of serological status to measles virus. A positive result generally indicates exposure to measles virus or previous vaccination. A positive result is considered adequate laboratory evidence of measles immunity. Persons with an equivocal serologic test result do not have adequate presumptive evidence of immunity and should be considered sesceptible unless they have other evidence of measles immunity. Documented age-appropriate vaccination supersedes the results of subsequent serologic testing. If a person who has two documented doses of measles-containing vaccine is tested serologically and is determined to have negative or equivocal measles results, it is not recommended that they receive an additional dose of vaccine. These individuals should be considered to have presumptive evidence of immunity.

Clinical Significance:
The test is useful in the diagnosis of spotted fever group rickettsial infections. Antibody reactivity to Rickettsia rickettsii antigen should be considered Spotted Fever group reactive. Other organisms within the group include R. akari, R. conorrii, R. australis and R. sibirica. This test is preferred for the acute or convalescent phase of disease. Acute and convalescent titers are often necessary. IgG serum endpoint titer of ≥1:64 is suggestive of infection at an unknown time and may be a sign of either past infection or early response to a recent infection. IgM titer of ≥1:64 is regarded as probable evidence of recent or ongoing infection. A four-fold or greater increase in titer between two serum samples drawn 1-2 weeks apart and tested in parallel is the best serologic indicator of a recent rickettsial infection.

Testosterone in males is secreted by adult Leydig cells and is controlled principally by lutenizing hormone (LH). The majority of serum testosterone is bound to sex hormone binding globulin (SHBG), but it also exists loosely bound to albumin and in the free state. An abnormally low total testosterone level in males can be indicative of hypogonadism, hypopituitarism, hyperprolactinemia, renal failure, hepatic cirrhosis, or Kleinfelter’s syndrome. High total testosterone values in males can be caused by adrenal and testicular tumors, congenital adrenal hyperplasia or abnormalities of the hypothalamic-pituitary-testicular axis.

Clinical Significance:
Thyrotropin-receptor antibody is an autoantibody to the thyroid cell receptor for thyroid-stimulating hormone. It can be demonstrated in 90% of patients with Graves' disease, and is the cause of the hyperthyroidism of that condition. The characterization of TRA resolved much confusion about long-acting thyroid stimulator (LATS) and LATS protector, which are both, in fact, thyroid-stimulating autoantibodies which simply behaved differently in animal test systems. These antibodies are present in 50% of euthyroid Graves' disease as well as hyperthyroid patients. They play a major role in the pathogenesis of Graves' disease. Detection of these antibodies is useful in prediction of neonatal hyperthyroidism and prediction of relapse of hyperthyroidism.

Clinical Significance:
Thyroxine is commonly measured in serum as total T4, measuring both bound and free T4. It is used as a thyroid screening test alone or in conjunction with other thyroid tests. Measurement of total T4 gives a reliable reflection of clinical thyroid status in the absence of binding abnormalities. However, changes in binding proteins can occur which affect the level of total T4, but leave the level of unbound hormone unchanged. The clinical importance of total T4 determination is in the diagnosis and confirmation of thyroid disorders. Elevated levels of T4 occur in Graves’ disease, subacute thyroiditis, toxic nodule, or secondary (pituitary) hyperthyroidism. Decreased levels occur primarily due to defects at the hypothalamic-pituitary level.

Clinical Significance:
Distinguish between high T4 levels due to hyperthyroidism and due to increased binding by TBG in euthyroid individuals who have normal levels of free hormones; document cases of hereditary deficiency or increase of TBG; work-up of thyroid disease. In patients with low T4, high T3 (uptake) or the reverse, who clinically seem eumetabolic and have normal FTI, measurement of TBG is only occasionally needed. Some such patients may have hereditary anomalies of TBG. TBG is increased by estrogens, tamoxifen, pregnancy, perphenazine, and in some cases of liver disease, including hepatitis. Decreased TBG is found with some instances of chronic liver disease, nephrosis and systemic disease, and with large amounts of glucocorticoids, androgens/anabolic steroids, and acromegaly. Although alterations of TBG are usually resolved by the thyroid profile, TBG must occasionally be directly measured. Kindreds are described with elevated TBG and hyperthyroxinemia as a harmless genetic abnormality. They have normal levels of TSH and free T4 and decreased T3 uptake.2 Structural variants of TBG are inherited as X-chromosome-linked traits, most inherited structural abnormalities in TBG cause decreased affinity for thyroid hormone.3

Trichomonas vaginalis infections cause vaginitis, urethritis and cervicitis. Discharge and small hemorrhagic lesions may be present in the genitourinary tract. Complications can include premature labor, low-birth-weight offspring, premature rupture of membranes and post-abortion or post-hysterectomy infection. An association with pelvic inflammatory disease, tubal infertility, and cervical cancer with previous episodes of trichomoniasis has been reported. Symptomatic women with trichomoniasis usually complain of vaginal discharge, vulvovaginal soreness and/or irritation. Dysuria is also common. However, it has been estimated that 10-50% of T. vaginalis infections in women are asymptomatic.

Clinical Significance:
Irinotecan (Camptosar®) is used, or under evaluation, in a broad spectrum of solid tumors, and is often prescribed for treating patients with metastatic cancer of the colon or rectum, especially when 5-fluorouracil treatment has not been entirely successful. Severe toxicity (eg, grade 4 neutropenia) is commonly observed in cancer patients receiving irinotecan who carry the UGT1A1*28 allele, also called TA. This test result will provide valuable information to physicians prior to initiating or modifying treatment or supplementing treatment with additional drugs. UGT1A1 variants have also been reported in patients with disorders of bilirubin metabolism, such as Crigler-Najjar Types I and II, as well as Gilbert syndrome. Between 80% to 100% of Caucasian patients with Gilbert syndrome are reported to have either one or two copies of UGT1A1*28. G71R (*6), a UGT1A1 variant reported in Asian patients with Gilbert syndrome, is not detected by this assay.

Clinical Significance:
Measurements of urea nitrogen are used in the diagnosis and treatment of certain renal and metabolic disorders. Blood Urea Nitrogen (BUN) levels are a measure of kidney function and also of prerenal and postrenal conditions. Prerenal causes of elevated BUN include cardiac decompensation, water depletion or increased protein catabolism. Among the renal causes of increased levels are acute glomerulonephritis, chronic nephritis, polycystic kidney, nephrosclerosis, and tubular necrosis. Any type of obstruction of the urinary tract is a postrenal cause for elevated BUN levels. Both urea and creatinine are cleared by the renal glomeruli, however, urea is subsequently partially reabsorbed by the renal tubules, while creatinine is not. Consequently, serum urea nitrogen and serum creatinine determinations are frequently performed together in the differential diagnosis of kidney function.

Clinical Significance:
This test is used to detect IgM antibodies specific for VZV. These IgM antibodies, if present, can help confirm a diagnosis of VZV acute infection. The IgM response to VZV can be detected at seven days postinfection and usually peaks at 14 days. If a patient presents more than nine days after the appearance of a rash, this assay should not be used. (See Varicella Zoster Virus (VZV) Antibodies, IgG [096206]).

Clinical Significance:
Vectra® DA measures the concentration of 12 serum proteins. An algorithm is applied to these concentrations to calculate a quantitate disease activity score ranging from 1 to 100. Test results are intended to aid in the assessment of disease activity in RA patients when used in conjunction with standard clinical assessment. This test is not intended or validated to diagnose RA. An order for Vectra® DA includes and requires an order for 12 biomarkers: VCAM-1, EGF, VEGF-A, IL-6, TNF-RI, MMP-1, YKL-40, Leptin, Resistin, SAA, CRP. These 12 biomarkers are required to generate the Vectra® DA test score. By ordering Vectra® DA, you are ordering all 12 biomarkers and are acknowledging that Labcorp cannot provide a Vectra® DA test result without these 12 biomarkers. Vectra® DA was validated in adults with Rheumatoid Arthritis (RA).

Clinical Significance:
Vitamin B12 is a coenzyme that is involved in two very important metabolic functions vital to normal cell growth and DNA synthesis. Deficiency of this vitamin can lead to megaloblastic anemia and ultimately to severe neurological problems. Vitamin B12 and folate are linked by the reaction pathway for methionine synthesis; a deficiency in either will disrupt this metabolic pathway and lead to the same symptoms and medical problems. It is usually necessary to measure both vitamins in a clinical work-up, with the treatment depending on which of the two is deficient.

Blood should be collected in a blue-top tube containing 3.2% buffered sodium citrate.1 Evacuated collection tubes must be filled to completion to ensure a proper blood-to-anticoagulant ratio.2,3 The sample should be mixed immediately by gentle inversion at least six times to ensure adequate mixing of the anticoagulant with the blood. A discard tube is not required prior to collection of coagulation samples unless the sample is collected using a winged (butterfly) collection system. With a winged blood collection set a discard tube should be drawn first to account for the dead space of the tubing and prevent under-filling of the evacuated tube.4,5 When noncitrate tubes are collected for other tests, collect sterile and nonadditive (red-top) tubes prior to citrate (blue-top) tubes. Any tube containing an alternative anticoagulant should be collected after the blue-top tube. Gel-barrier tubes and serum tubes with clot initiators should also be collected after the citrate tubes. Please print and use the Volume Guide for Coagulation Testing to ensure proper draw volume.
