Order Free T3 Levels Test | Thyroid Testing (FT3)The Free T3 Levels Test measures the unbound portion of triiodothyronine, the active thyroid hormone that influences metabolism, energy use, and temperature regulation. Because this fraction circulates unattached to carrier proteins, it offers a direct view of hormone available to tissues rather than a total that can be skewed by binding-protein concentrations.
About Free T3 Levels Test | Thyroid Testing (FT3) in Bend
Triiodothyronine, commonly abbreviated T3, is one of the two principal hormones produced by the thyroid gland, with the other being thyroxine, or T4.
Most T3 in the bloodstream is created when T4 is converted in peripheral tissues such as the liver and kidneys, a step that allows the body to fine-tune hormone activity at the cellular level.
Once released, T3 travels largely bound to proteins like thyroxine-binding globulin and albumin; only a small percentage remains free and biologically active.
Because protein levels can shift with factors such as liver function, pregnancy, or medication, measuring free T3 rather than total T3 can give a clearer picture of the hormone actually available to cells.
