The Free Triiodothyronine (Free T3) Test by AeHealth measures the level of unbound T3 hormone in the bloodstream, which represents the biologically active form of thyroid hormone. Unlike total T3, the Free T3 test evaluates the hormone available to tissues, providing a more accurate reflection of thyroid function.
This test plays a crucial role in the diagnosis and monitoring of thyroid disorders, especially hyperthyroidism, hypothyroidism, and thyroid hormone conversion issues.
