What This Test Measures

Comprehensive panel covering TSH, Free T4, Free T3, Reverse T3, TPO Ab, and TgAb.

Preparation

No fasting required
If taking T3 medication (liothyronine/Cytomel), draw at least 12–24 hours after your last dose for an accurate TSH. If splitting T3 doses, draw at your natural trough. Biotin supplements — even in multivitamins — can falsely skew thyroid results: discontinue at least 2 days before testing. No fasting required unless combined with other tests.

General guidelines only. Requirements vary by lab and individual. Confirm with your provider before adjusting any medications.
