This panel measures both total testosterone and free testosterone (the portion not bound to proteins and available for your body to use). Free testosterone is often a more meaningful marker because it represents the biologically active hormone. Total testosterone can appear normal while free testosterone is low, especially in older men or those with high SHBG levels. Total testosterone is measured by LC-MS/MS at both labs (Quest test 36170, Labcorp 070195) — the CDC-certified reference method, not an immunoassay. Free testosterone is by equilibrium dialysis at Quest (the method guidelines prefer) and by Labcorp's direct assay at Labcorp; Quest reports total testosterone from 1 to 10,000 ng/dL.
Pairs Total Testosterone with calculated Free Testosterone — the bioavailable fraction that drives symptoms. The single best lab workup for suspected low T.
Men investigating low T symptoms (low libido, ED, fatigue, mood, recovery), monitoring TRT, or with normal total T but persistent symptoms (often due to high SHBG binding active hormone).

What can throw off this result
Physician-reviewed “Before your test” pages — what each factor does, for how long, and what to do about it.
A Free & Total Testosterone test costs $54.99 at TestWell — $60.99 all-in when ordered alone, because the $6 lab processing fee is charged once per order, with no draw fee or physician fee added. Hospital outpatient labs typically bill around $250.00 self-pay for the same test, and often more. With insurance, what you pay depends on your deductible and your plan's negotiated rate; TestWell's price is fixed before the draw and is HSA/FSA-eligible.
| Where you order | Price | One test, all-in | Notes |
|---|---|---|---|
| TestWell (drawn at Quest) | $54.99 | $60.99 | Includes the one $6 lab processing fee, charged once per order |
| TestWell (drawn at Labcorp) | $74.99 | $80.99 | Labcorp's own cost for this test is higher; same order, same portal, same physician review |
| TestWell (drawn at BioReference — New York & New Jersey) | $46.99 | $52.99 | New York and New Jersey orders route to BioReference; Quest Health and Labcorp OnDemand don't take self-ordered draws in those states |
| Hospital outpatient lab, self-pay (typical) | $250.00 | $250.00 | Reference figure; hospital charges vary widely by facility and are often higher |

About 98% of total testosterone is bound to proteins (mostly SHBG) and inactive. Free testosterone is the small fraction available to tissues — and the better predictor of symptoms. Total T can be normal while Free T is low.
Free & Total is the better single test for symptom investigation. Order Total T alone only when monitoring established TRT at a known SHBG baseline.
TestWell charges $54.99 — vs $89 at Quest Direct and $150-$300 at hospital outpatient labs. Quest or Labcorp lab.
Yes — morning fasting draw between 7-10 AM is standard. Testosterone follows a strong diurnal rhythm; afternoon draws can underestimate by 20-30%.
Reference range: 47-244 pg/mL (men, varies by lab). Symptoms often appear when Free T drops below 70 pg/mL even if Total T is in range.
Yes if Free T is low but Total T is normal — high SHBG (often from low thyroid, hyperthyroidism, or aging) explains the discrepancy. Order SHBG alongside, or use our Men's Hormone Panel which bundles it.
Yes — total testosterone is measured by LC-MS/MS at both labs (Quest test 36170, Labcorp 070195), the CDC-certified reference method rather than the basic immunoassay. Free testosterone differs by lab: Quest measures it by equilibrium dialysis, the method endocrinology guidelines prefer; Labcorp uses its direct free-testosterone assay. If you are on testosterone therapy and expect high values, Quest reports total testosterone up to 10,000 ng/dL.
Free & Total Testosterone test results are typically ready in 3–5 business days after your draw at Quest or Labcorp. TestWell emails you the moment they post, and your results dashboard shows each marker against its reference range with a plain-English explanation.
Biotin supplements, exercise, time of day and common medications can change a Free & Total Testosterone test result without anything being wrong. Biotin supplements can shift Total Testosterone — stop biotin ≥72 hours; tell the lab if you can't. Exercise can raise Total Testosterone — draw in the morning before training. Time of day can shift Total Testosterone — draw 7–10 a.m.; confirm a low result with a second morning draw. Common medications can lower Total Testosterone — note the medication on hormone results. Each factor is covered on our physician-reviewed "Before your test" pages; when one applies, the fix is usually to remove it and retest.
