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, body temperature, heart rate, and protein synthesis. Because T3 circulates in both free and protein-bound forms, this test helps evaluate thyroid function and can reveal whether a T3 deficiency is present.
About Triiodothyronine Hormone T3 Test in Holladay
Triiodothyronine, or T3, is the biologically active thyroid hormone that influences nearly every cell in the body.
The thyroid gland produces T3 in smaller amounts than thyroxine, or T4, but T3 is several times more potent. Most T3 in the bloodstream is created when T4 is converted into T3 in tissues such as the liver and kidneys. The hormone travels attached to carrier proteins, and only the unbound, or free, portion is available to enter cells and exert its effects.
A T3 test is typically ordered when a person shows signs of an overactive or underactive thyroid, or when a T4 result is abnormal. It can help distinguish between different forms of thyroid dysfunction and assess whether the body is converting T4 into T3 effectively. Results are usually interpreted alongside other thyroid markers, including TSH and T4.
Abnormal T3 levels can occur in conditions such as hyperthyroidism, hypothyroidism, and certain illnesses that affect hormone conversion. Some medications and acute stress can also influence results. Because thyroid hormones interact with many body systems, a single measurement is best understood in the context of a person's overall clinical picture and additional laboratory findings.
