Quick answer
The free testosterone direct test measures the amount of testosterone that is not bound to proteins in the blood. This unbound fraction is available for tissues to use, so it can offer a clearer view of hormone activity than total testosterone alone. It is ordered when symptoms suggest an imbalance or when a total result does not match the clinical picture.
About this test in Acton
Most testosterone in the blood travels attached to proteins, mainly sex hormone-binding globulin and albumin. Only a small percentage circulates unbound, and this free fraction is considered the biologically active portion. Direct measurement of free testosterone avoids some of the assumptions used in calculated methods, which depend on other values such as SHBG and total testosterone.
The test uses a blood sample, usually collected in the morning when testosterone is highest. The laboratory measures the free hormone directly with a specialized assay. Results are reported as a concentration and compared with a reference range that varies by age and sex. Free testosterone can be useful when total testosterone is borderline or when binding proteins are abnormal.
Clinicians may order this test for symptoms of low testosterone such as fatigue, reduced libido, or mood changes, especially when total testosterone is not clearly low. It can also help evaluate conditions that alter binding proteins. A single result is interpreted with the person's history, and repeat testing may be advised.
