About This Test

The Free Testosterone Test is a specialised blood test that measures the amount of testosterone that is not bound to proteins in the blood, the biologically active form of the hormone. Free testosterone plays a critical role in male and female health, influencing sexual development, libido, muscle mass, bone strength, and overall energy. Unlike total testosterone tests, which include both bound and unbound forms, the free testosterone test provides a clearer picture of hormonal balance, especially in patients with unexplained symptoms and normal total testosterone. Doctors may order this test to evaluate male infertility, erectile dysfunction, delayed or early puberty in children, and signs of androgen excess in women, such as hirsutism or PCOS. Chronic illnesses, obesity, ageing, or medication use can also affect free testosterone levels. Regular monitoring guides personalised hormone therapy, reproductive planning, and helps diagnose a variety of endocrine conditions crucial for well-being.
