Free testosterone is the unbound, biologically active form of testosterone in the bloodstream. This test measures the amount of testosterone not attached to proteins, which is available for use by the body's tissues. It's crucial for assessing androgenic status, especially in cases where total testosterone levels may be normal but free testosterone is low. This test is particularly useful in diagnosing hypogonadism, monitoring testosterone replacement therapy, and evaluating conditions such as erectile dysfunction, infertility, and certain hormonal imbalances in both men and women.
A low free testosterone reading may indicate:
Low levels can lead to decreased libido, erectile dysfunction, reduced muscle mass, increased body fat, fatigue, and mood changes. In women, it may affect bone density and sexual function.
An elevated free testosterone reading may suggest:
High levels in men can lead to acne, male pattern baldness, and aggressive behavior. In women, it may cause hirsutism (excessive hair growth), acne, menstrual irregularities, and virilization (development of male characteristics).
