    What Is a Free T4 (FT4) Test?

    The Free T4 (FT4) test measures the level of unbound thyroxine (T4) hormone in the blood. T4 is produced by the thyroid gland and plays a vital role in regulating metabolism and growth.

    This test specifically evaluates the free (biologically active) form of thyroxine, which is not bound to proteins and can directly affect body cells. It helps in diagnosing thyroid disorders such as hypothyroidism and hyperthyroidism, and in monitoring treatment effectiveness in patients with known thyroid conditions.

    Orange Health Labs provides convenient at-home sample collection for Free T4 tests across multiple cities, with rapid report delivery.

    Free T4 (FT4) Test Price
