About Free T3 Levels Test | Thyroid Testing (FT3) in Berkeley
Free T3 reflects the biologically active share of triiodothyronine circulating in the blood.
Most triiodothyronine in the bloodstream is attached to carrier proteins such as thyroxine-binding globulin, albumin, and transthyretin. Only the unbound remainder, called free T3, can enter cells and exert metabolic effects.
Measuring free T3 rather than total T3 reduces the influence of shifts in binding-protein concentrations, which can change for reasons unrelated to thyroid function. This makes the free fraction a more consistent indicator of thyroid hormone activity.
Free T3 is typically interpreted alongside other thyroid markers, including thyroid-stimulating hormone and free T4, because no single value describes the full picture of thyroid regulation.
