About Free T3 Levels Test | Thyroid Testing (FT3) in Fallbrook
Free T3 reflects the biologically available thyroid hormone.
Triiodothyronine, commonly called T3, is a thyroid hormone that acts on nearly every cell in the body. Most T3 in the bloodstream is bound to transport proteins such as thyroxine-binding globulin and albumin, leaving only a small fraction free to enter tissues and exert effects.
Measuring free T3 rather than total T3 avoids distortions that can occur when binding-protein levels change. Pregnancy, liver conditions, and certain medications may alter protein concentrations, so the free hormone measurement can provide a more stable picture of the active hormone available to tissues.
Free T3 is typically interpreted alongside other thyroid markers, including thyroid-stimulating hormone (TSH) and free T4. Clinicians use these results together to evaluate thyroid function and to distinguish between different patterns of thyroid dysfunction.
