The Free Triiodothyronine (Free T3) test measures the level of free T3 hormone in the blood, which is the active form of the thyroid hormone. T3 is responsible for regulating important body functions like metabolism, energy levels, heart rate, weight, and mood. Unlike the total T3 test, which includes both bound and free T3, the Free T3 test measures only the active form that your body can use. This test is crucial for diagnosing thyroid conditions, including hyperthyroidism (overactive thyroid), and evaluating overall thyroid health. Abnormal levels of free T3 may point to thyroid issues or other related disorders.
