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 [070001], which employs liquid chromatography/tandem mass spectrometry (LC/MS-MS), is recommended.
