What do your Total T3 levels mean?
The short answer
Nobody we follow has said what your Total T3 should be. It comes up on the shows, but never with a number.
Your lab prints 80–200 ng/dL. That range exists to catch disease, not to describe your best.
What Total T3 measures
All the active thyroid hormone in your blood, both bound and unbound.
Proteins hold most of it inactive, so it goes alongside the free form.
Checked against MedlinePlus — Triiodothyronine (T3) Tests.
