What Is a Free Testosterone Test?
A Free Testosterone test measures the small portion of testosterone in your blood that is not bound to proteins and is freely available for your body to use. Most testosterone in the blood is attached to proteins such as SHBG (sex hormone binding globulin) and albumin, and that bound portion is largely inactive. The free fraction is what actually reaches your tissues and does the work. Because of this, a free testosterone test can give a clearer picture than total testosterone alone, especially when protein levels are abnormal.
Why Is a Free Testosterone Test Done?
In men, this test is used to investigate low sex drive, erectile difficulty, tiredness, loss of muscle, or infertility, and to help diagnose low testosterone (hypogonadism). In women, it is often ordered when there are signs of higher-than-normal male hormones, such as irregular periods, excess facial or body hair, acne, or hair thinning, which can point to conditions like polycystic ovary syndrome (PCOS). It is also used to monitor people already on hormone therapy. Doctors usually look at free testosterone together with total testosterone and SHBG for the full story.
Normal Free Testosterone Levels
Reference ranges vary widely between laboratories and depend heavily on age, sex, and the exact method used, so the range printed on your own report matters most. As a general guide, adult men typically fall around 50 to 210 picograms per millilitre (pg/mL), while adult women have far lower levels, roughly 1 to 9 pg/mL. Levels naturally decline with age in men. Because methods differ, never compare a result from one lab directly against another lab's range, and always let your doctor interpret the number alongside your symptoms.
How to Prepare for the Free Testosterone Test
- The sample is usually taken in the morning, ideally between 7 and 10 a.m., because testosterone is highest at that time.
- Fasting is not normally required, but follow any instruction your doctor gives.
- Tell the lab about any hormone medicines, steroids, or supplements you take, as these affect the result.
- Mention any recent illness or major stress, since these can temporarily lower testosterone.
