Order Triiodothyronine Hormone T3 TestThe Triiodothyronine Hormone T3 Test measures the amount of triiodothyronine, commonly called T3, in the blood. T3 is one of the two primary hormones produced by the thyroid gland, and it plays a central role in regulating metabolism, heart rate, body temperature, and energy use. Because T3 circulates in both free and protein-bound forms, this test helps evaluate overall thyroid function and can reveal whether a T3 deficiency is present.
About Triiodothyronine Hormone T3 Test in Bothell
Understanding T3 and what the test measures
Triiodothyronine is the more biologically active of the thyroid hormones. While the thyroid gland secretes a smaller amount of T3 directly, most T3 is created when the body converts thyroxine (T4) into T3 in peripheral tissues such as the liver and kidneys. Only a small fraction of circulating T3 is unbound, or "free," and this free portion is the form that can enter cells and exert its effects.
The T3 test is typically ordered when a person has symptoms that suggest abnormal thyroid function, such as unexplained weight changes, fatigue, sensitivity to temperature, or changes in heart rate. It is often interpreted alongside other thyroid markers, including thyroid-stimulating hormone (TSH) and T4, to build a more complete picture of how the thyroid axis is working.
Results from a T3 test are not read in isolation. Clinicians consider the pattern across multiple thyroid tests, along with a person's medical history and current medications, because several factors can influence T3 levels. The test itself involves a standard blood draw, and the lab follows its own instructions regarding any preparation.
