The Complete Thyroid Panel combines every major thyroid marker into a single comprehensive order. It includes TSH, Free T4, Free T3, Reverse T3, and TPO Antibodies. This is the panel functional medicine practitioners often recommend because it evaluates not just whether the thyroid is working, but how well it's converting T4 to active T3, whether reverse T3 is blocking thyroid function, and whether autoimmune thyroid disease is present.
5 thyroid tests: TSH, Free T4, Free T3, Reverse T3, TPO Antibodies. The most thorough single-draw thyroid evaluation — distinguishes primary vs central, conversion issues, and autoimmune causes.
Anyone with classic thyroid symptoms (fatigue, weight changes, cold intolerance, hair thinning, brain fog) whose TSH alone hasn't given clear answers, anyone managing known thyroid disease, anyone with autoimmune disease (T1 diabetes, celiac, RA) checking for thyroid involvement.
