Measures only the biologically active free testosterone — the hormone your body can actually use. Free testosterone measures the small percentage of testosterone that is not bound to proteins (SHBG or albumin) and is available for tissues to use. It's particularly useful when total testosterone is borderline or normal but symptoms of low testosterone are present. Conditions like obesity, aging, and certain medications can increase SHBG binding, making free testosterone a more accurate measure. **Clinical use:** Measures the unbound, biologically active testosterone in the bloodstream. Useful when Total testosterone is normal but symptoms persist, or when SHBG is abnormal. ## Who should order it? Men with low T symptoms but normal Total testosterone, anyone with abnormal SHBG, men on TRT, women evaluating PCOS or unexplained hirsutism, anyone with thyroid disease (which alters binding). ## Biomarkers measured - [Free Testosterone](https://www.test-well.com/biomarkers/free-testosterone) ## Price by lab | Lab | Test price | All-in (with $6 fee) | Notes | | --- | --- | --- | --- | | Quest Diagnostics | $33.99 | $39.99 | Choose at checkout; walk-in patient service centers nationwide (not NY/NJ) | | Labcorp | $36.99 | $42.99 | Choose at checkout; walk-in patient service centers nationwide (not NY/NJ) | | BioReference (NY & NJ) | $36.99 | $42.99 | New York and New Jersey orders route here automatically | Rhode Island is not served.

Total testosterone includes all the hormone in your blood — most is tightly bound to SHBG (inactive). Free testosterone measures the small unbound fraction (~1-2%) that tissues can actually use. Free is the more clinically relevant marker when SHBG is high or low, which happens in obesity, thyroid disease, liver disease, and aging. ### What's a normal Free testosterone level? Men 20-49: 5.0-21.0 ng/dL or 1.2-2.5% of total. Men 50+: 4.0-18.0 ng/dL. Women: 0.1-0.85 ng/dL. The percentage matters as much as the absolute number — Free T below 1.5% of Total in a symptomatic man often warrants treatment even if Total looks normal. ### Should I get Free or Total testosterone? Both, ideally. Get the bundled [Testosterone Free & Total](https://www.test-well.com/tests/testosterone-free-and-total) for the complete picture. Order Free alone only if you've already established Total is normal and want to confirm bioavailability. ### How much does a Free testosterone test cost without insurance? On TestWell, the Testosterone test (Free + Total combination) is $33.99. Quest Direct lists the same bundle at $60, walk-in hospital labs typically bill $150-180 without insurance. ### What's the CPT code for Free testosterone? The CPT code for Testosterone, Free is 84402. Total testosterone is 84403. When ordered together, both codes appear on the requisition. ### When should I draw blood for a Free testosterone test? Morning (7-10 AM) is the standard — testosterone peaks early. Two separate morning draws are recommended to confirm low T before starting treatment, per Endocrine Society guidelines. ### How is Free testosterone calculated vs measured? Direct measurement uses equilibrium dialysis (gold standard, expensive). Most labs calculate Free T from Total testosterone + SHBG + albumin using the Vermeulen equation — accurate and far cheaper. Both methods are accepted clinically; calculated Free T is what most TRT clinics use. ## How to order 1.
