About Free T3 Levels Test | Thyroid Testing (FT3) in St. Louis Park
Free T3 reflects the fraction of triiodothyronine circulating unbound to carrier proteins.
Most triiodothyronine in the bloodstream is attached to proteins such as thyroxine-binding globulin and albumin. Only the unbound, or free, portion is biologically available to tissues.
Because Free T3 is measured independently of binding-protein concentrations, it can offer a clearer view of thyroid hormone activity than total T3 in situations where protein levels vary.
Clinicians may order Free T3 alongside other thyroid markers to evaluate how the thyroid axis is functioning and to interpret patterns across related tests.
