Order Triiodothyronine Hormone T3 TestThe Triiodothyronine Hormone T3 Screen measures triiodothyronine, one of the two principal hormones produced by the thyroid gland. While T4 receives much of the attention in thyroid discussions, T3 is the more biologically active form and exerts a direct influence on cellular metabolism. This test helps characterize thyroid function by quantifying T3 in the bloodstream.
About Triiodothyronine Hormone T3 Test in Orem
Triiodothyronine, commonly abbreviated T3, is a hormone that regulates the rate at which cells convert nutrients into energy.
The thyroid gland secretes T3 alongside thyroxine, or T4. Most circulating T3 is not produced directly by the thyroid; instead, it is created when T4 is converted in peripheral tissues such as the liver and kidneys. This conversion step means T3 levels can diverge from T4 levels, which is one reason clinicians may order a T3 measurement rather than relying on T4 alone.
In the bloodstream, T3 travels in two forms. The majority is bound to transport proteins, while a smaller fraction circulates unbound, or free. Bound T3 serves as a reservoir, whereas free T3 is the portion available to enter cells and act on them. A T3 test may report total T3, which includes both fractions, or free T3 specifically, depending on the panel and the clinical question.
Because T3 drives metabolic activity across nearly every organ system, its measurement can be useful when thyroid dysfunction is suspected but T4 results are ambiguous. Results are interpreted alongside other thyroid markers and the broader clinical picture; a single value rarely stands alone. Turnaround for this test is typically one to three business days, and preparation follows the lab's instructions.
