Free testosterone blood test results provide additional information that can be used for screening or tracking purposes. More specifically, capturing the free testosterone level may be of use when someone is undergoing testosterone replacement, a hypogonadism workup and a hyperandrogenism evaluation in a woman. Additionally, free testosterone is a useful measurement when SHBG levels might be low such as in people with liver and chronic diseases like PCOS, genetic SHBG conditions, and people who are being treated with corticosteroids or estrogen.
