Measures Free T3, the most biologically active thyroid hormone, to detect T4-to-T3 conversion issues TSH and T4 alone miss.
The Free T3 Test is for anyone who wants a clear, reliable picture of their health — whether you're staying ahead of a known risk, tracking how things change over time, or simply want answers to questions everyday life can't explain.
It's especially worth doing if symptoms run in your family, you're managing your weight or energy, or you want a baseline you can build on. No doctor's referral is needed to book this test, and a licensed clinician reviews every result.
Every biomarker in this panel, and exactly what it tells you.
