Diagnostic Use / Indications

Testosterone, a hormone produced in the interstitial tissue of the testis in male and the adrenals in both sexes , functions in the induction and maintenance  of secondary sex characteristics.  The testosterone levels in plasma provide useful indices of androgen production in males. Measurement also necessary for diagnosis and management of Endocrine disorders such as Klinefelter's and Stein Levanthal syndromes, testicular feminisation (males) and testosterone producing tumours in both adrenal and ovary. High levels in women are found in hirsutism, virilisation and polycystic ovaries  while high levels in males can indicate prostate cancer.
