If you’ve ever been told your thyroid labs are “normal” while you’re still gaining weight, losing hair, freezing in 75-degree weather, and dragging through your afternoons — you are not imagining things.
Most standard panels test TSH alone. A complete picture requires Free T3, Free T4, Reverse T3, TPO antibodies, and TgAb — because subclinical hypothyroidism, Hashimoto’s, and conversion issues all hide behind a “normal” TSH.
Reference ranges are also wider than what most people would call optimal. “In range” is not the same as “where your body actually thrives.”
What we look for at iRevive:
✅ Free T3 in the upper third of range — the active thyroid hormone your cells use
✅ Reverse T3 not blocking conversion
✅ No autoimmune antibodies driving silent inflammation
✅ A pattern that matches how you actually feel
When the picture is complete, the protocol can be precise. And when the protocol is precise, you finally feel the difference.
