Immunology Tests

Measurement of luteinizing hormone (LH) in serum helps evaluate reproductive function. It is used in diagnosing and monitoring disorders of the pituitary and gonads, assessing fertility, evaluating menstrual irregularities, and confirming ovulation in women or testosterone production in men.

Measurement of insulin helps in the diagnosis of diabetes mellitus and in the differential diagnosis of fasting hypoglycemia, distinguishing between insulinoma and factitious hypoglycemia. It can also be used to assess hyperinsulinemia as a potential risk factor for coronary artery disease in otherwise healthy individuals with normal glucose tolerance.

Qualitative detection of antibodies against HTLV I and HTLV II in human serum. Detection of antibodies against HTLV-I and HTLV-II serves to aid in the diagnosis of HTLV infection and to protect the safety of blood supply.

An aid for screening and monitoring patients suspected of having an inherited disorder of methionine metabolism. Evaluating individuals with suspected deficiency of vitamin B12 or folate.

The simultaneous qualitative detection of HIV p24 antigen and antibodies to human immunodeficiency virus type 1 and/or type 2in human serum. It is intended to be used as an aid in the diagnosis of HIV-1/HIV-2 infection and as a screening test to prevent transmission of HIV-1/HIV-2 to recipients of blood, blood components, cells, tissues and organs.

The qualitative detection of hepatitis B surface antigen in human serum. It is used as an aid in the diagnosis of acute, recent, or chronic hepatitis B.

Determining the presence or absence of detectable hepatitis B virus e antigen in monitoring infection status of individuals with chronic hepatitis B. Determining infectivity of hepatitis B virus (HBV) carriers. Monitoring serologic response of chronically HBV-infected patients receiving antiviral therapy.

Qualitative detection of IgM antibodies to hepatitis A virus (anti-HAV IgM) in human serum. This is indicated for use as an aid in the diagnosis of acute or recent Hepatitis A viral infection.

Qualitative detection of IgG antibodies to hepatitis A virus (anti-HAV IgG) in human serum. This test aids in the diagnosis of hepatitis A infection and in determining immune status. The presence of IgG anti-HAV with a non-reactive IgM anti-HAV result indicates past infection with hepatitis A virus or immunity due to vaccination.

Aiding in discriminating between prostate cancer and benign prostatic conditions in men aged 50 years and older with total PSA between 4.0 and 10.0 ng/mL.

Investigation of suspected folate deficiency. Folate deficiency can be caused by low dietary intake, malabsorption due to gastrointestinal diseases, inadequate utilization due to enzyme deficiencies or folate antagonist therapy.

Measurement of free triiodothyronine (FT3) in serum helps assess thyroid function. FT3 is often more elevated than FT4 in Graves disease, and in about 5% of hyperthyroid patients, FT3 may be elevated alone (T3-toxicosis). In contrast, FT4 levels are usually higher than FT3 in toxic multinodular goiter and in cases of excessive T4 therapy. Therefore, serum FT3 helps distinguish between different types of hyperthyroidism.

Evaluating suspected thyroid function disorders using free thyroxine measured together with thyroid-stimulating hormone. It is used in the diagnosis and monitoring of hyperthyroidism and hypothyroidism and assists in assessing the effectiveness of thyroid treatment.

Measurement of ferritin levels helps assess the body’s iron stores. It aids in diagnosing iron deficiency and iron overload conditions and helps differentiate between iron deficiency anemia and anemia of chronic disease.

The qualitative detection of IgM antibodies to Epstein-Barr Virus (EBV) Viral capsid antigen. The assay is intended to be used as an aid in the diagnosis of infectious mononucleosis and an aid in determining the stage of EBV infection.

The qualitative detection of IgG antibodies to Epstein-Barr Virus (EBV) Viral capsid antigen. The assay is intended to be used as an aid in the diagnosis of infectious mononucleosis and an aid in determining the stage of EBV infection.

Estradiol is the most potent natural estrogen in human. It regulates reproductive function in females, and, with progesterone, maintains pregnancy.

DHEA-S is the most abundant adrenal androgen and also functions as a neurosteroid that is produced by the adrenal cortex. DHEA-S is an excellent indicator of adrenal androgen production. Serum concentrations decline with age and can serve as a prognostic factor in both critical illnesses and breast cancer progression. Elevated levels of DHEA-S are found in patients with adrenal tumors or congenital adrenal hyperplasia. It can also be slightly elevated in patients with polycystic ovaries.

Aiding in the diagnosis and treatment of patients with abnormal insulin secretion including diabetes mellitus.

Aiding in the diagnosis and treatment of adrenal disorders. Cortisol is the major glucocorticoid hormone secreted by the adrenal cortex. Its physiological functions include regulation of carbohydrate metabolism and electrolyte and water distribution. Cortisol also has immunosuppressive and anti-inflammatory activity.

Determining whether a patient has had previous exposure to or recent infection with cytomegalovirus, including pregnant women. Infections with CMV, a member of the herpesvirus family, are common in man and are usually mild and asymptomatic. However, in pregnant women, newborns and immunocompromised individuals, CMV infections may pose a significant medical risk.

For the qualitative detection of IgM antibodies to Cytomegalovirus in human serum. Infections with CMV, a member of the herpesvirus family, are common in man and are usually mild and asymptomatic. However, in pregnant women, newborns and immunocompromised individuals, CMV infections may pose a significant medical risk. Detection of IgM-class antibodies to cytomegalovirus may be useful to assess for recent infection with cytomegalovirus.

Aiding in the prognosis sand management of colorectal cancer patients and other cancers such as medullary thyroid carcinoma. This test is not useful for screening the general population for undetected cancers.

Managing breast cancer patients when used in conjunction with clinical information and other diagnostic procedures. Serial testing to assist in early detection of disease recurrence in previously treated stage II and III breast cancer patients. This test is not useful as a cancer screening test.
