THIS IS A BLOOD DRAW TEST THAT IS PERFORMED AT A LABCORP PATIENT SERVICE CENTER NEAR YOU.
Use: Testosterone testing is used to evaluate androgen excess or deficiency related to gonadal function, adrenal function, or tumor activity. Testosterone levels may be helpful in men for the diagnosis of hypogonadism, hypopituitarism, Klinefelter syndrome, and impotence (low values). Testosterone levels may be requested in women to investigate the cause of hirsutism, anovulation, amenorrhea, virilization, masculinizing tumors of the ovary, tumors of the adrenal cortices, and congenital adrenal hyperplasia (high values). Testosterone levels in children may be helpful to investigate issues related to puberty and development as well as the aforementioned. For testosterone measurements in females and children, use of Testosterone, Total, Women, Children, and Hypogonadal Males, LC/MS-MS , which employs liquid chromatography/tandem mass spectrometry (LC/MS-MS), is recommended.
Limitations: In patients receiving therapy with high biotin doses (ie, >5 mg/day), no sample should be taken until at least eight hours after the last biotin administration.1 As with all tests containing monoclonal mouse antibodies, erroneous findings may be obtained from samples taken from patients who have been treated with monoclonal mouse antibodies or have received them for diagnostic purposes.1 In rare cases, interference due to extremely high titers of antibodies to streptavidin and ruthenium can occur.1 The test contains additives, which minimize these effects.
A LABCORP REQUISITION FORM WILL BE PROVIDED AT CHECK-OUT. BRING THAT FORM TO A LABCORP PATIENT SERVICE CENTER TO HAVE YOUR BLOOD DRAWN.
