Triiodothyronine – Free (FT3) is a blood test that measures the unbound, biologically active form of triiodothyronine (T3) hormone circulating in the bloodstream. FT3 plays a critical role in regulating metabolism, heart rate, body temperature, and energy levels. This test is commonly used in the evaluation of hyperthyroidism, hypothyroidism, and other thyroid disorders. FT3 is often interpreted alongside TSH and Free T4 (FT4) as part of a thyroid function panel.
