When ready, your results will be delivered in a clear, easy-to-understand report. If any results suggest a potential infection, you’ll receive a call from an independent healthcare coordinator. Independent physicians are also available to answer any questions or discuss your results in detail.

Test Details & What It Measures
A Free Testosterone test measures the level of unbound (active) testosterone in your blood, which is the form of testosterone that is readily available for use by the body’s cells. Testosterone, although primarily known as a male hormone, is also present in women in much smaller amounts. The majority of testosterone in the bloodstream is bound to proteins like sex hormone-binding globulin (SHBG) and albumin, and only a small percentage remains free, allowing it to exert its effects on tissues such as muscle, bone, and reproductive organs. The Free Testosterone test is often used to get a more accurate assessment of the active hormone levels, particularly when there are symptoms of hormone imbalance, such as low libido, fatigue, mood changes, or changes in muscle mass.
Free testosterone levels are often measured in conjunction with total testosterone to provide a complete picture of hormonal health. Normal free testosterone levels for adult men generally range from 50 to 210 pg/mL, while in women, the normal range is usually much lower, from 0.3 to 1.9 ng/dL, depending on the lab. Low levels of free testosterone may indicate hypogonadism (low testosterone), which can cause symptoms like fatigue, low sex drive, and decreased muscle mass, while high levels can be linked to conditions such as polycystic ovary syndrome (PCOS) or androgen-secreting tumors.
