Clinical significance

Free testosterone corresponds to the fraction not bound to albumin, transcortin or TEBG which represents about 2% of total testosterone in males and 1% in females. Reduced levels are observed in males with hypogonadism, hyperthyroidism or being treated with LHRH analogs. Increased levels are seen in females with hyperandrogenism (hirsutism and Stein-Leventhal syndrome).
