Order Triiodothyronine Hormone T3 TestThe Triiodothyronine Hormone T3 Test measures the amount of triiodothyronine in the bloodstream, a hormone produced primarily by the thyroid gland. Because T3 is the biologically active form of thyroid hormone, its concentration offers a direct view of how effectively the thyroid is driving metabolism in peripheral tissues. This test is typically used alongside other thyroid markers to characterize overall thyroid function and to identify situations in which T3 levels fall outside the expected range.
About Triiodothyronine Hormone T3 Test in Hampton
Triiodothyronine, commonly abbreviated T3, is one of the two principal hormones secreted by the thyroid gland, the other being thyroxine, or T4.
Most circulating T3 is not made directly by the thyroid; roughly eighty percent is generated when T4 is converted to T3 in tissues such as the liver and kidneys. This conversion step means that T3 measurements can reveal information that T4 alone does not capture.
In the blood, the great majority of T3 is bound to carrier proteins, while a small fraction circulates unbound, or free. The free portion is the metabolically active form, and laboratory methods may report total T3, free T3, or both depending on the panel ordered.
Because thyroid hormones influence heart rate, body temperature, weight, and energy use, abnormal T3 concentrations can accompany a range of clinical presentations. Results are interpreted in context with thyroid-stimulating hormone, T4, and the patient's overall clinical picture rather than in isolation.
