Order Triiodothyronine Hormone T3 TestThe Triiodothyronine Hormone T3 Screen measures the amount of triiodothyronine in the bloodstream, a hormone produced largely through the conversion of thyroxine (T4) in peripheral tissues. Because T3 is the biologically active form of thyroid hormone, its concentration offers a direct view of how much hormone is available to act on cells throughout the body.
About Triiodothyronine Hormone T3 Test in Orem
Thyroid function depends on a feedback loop involving the hypothalamus, pituitary gland, and thyroid gland, and T3 sits at the effector end of that loop.
Most circulating T3 is not made by the thyroid gland itself. The thyroid secretes a smaller proportion directly, while the majority is generated when T4 is deiodinated in the liver, kidneys, and other tissues. This conversion step means T3 levels can shift independently of how much T4 is being produced.
In the blood, the great majority of T3 is bound to carrier proteins such as thyroxine-binding globulin, albumin, and transthyretin. Only a small fraction circulates unbound, or free, and that free portion is the metabolically active component. Assays may report total T3, which includes bound and free hormone, or free T3 specifically.
Clinicians order T3 testing to investigate suspected hyperthyroidism, to distinguish among forms of thyroid disease, and to assess whether tissues are receiving adequate active hormone. Results are typically interpreted alongside TSH and T4, since any single value in isolation can be misleading.
