Quick answer
The T3 test measures triiodothyronine, one of the hormones produced by the thyroid gland. T3 is the more active form of thyroid hormone and influences metabolism, heart rate, and body temperature. The test may measure total T3, which includes bound and free hormone, or free T3, which reflects the unbound, active portion. It is interpreted with TSH and T4 by a healthcare provider.
What this test measures
The thyroid gland produces two main hormones: thyroxine, called T4, and triiodothyronine, called T3. Most T3 in the blood is created when T4 is converted in tissues, and T3 is the form that acts most strongly on cells. Because T3 is largely bound to carrier proteins, free T3 is the fraction available to affect the body.
A blood sample is drawn from a vein, usually at the arm, and analyzed in a laboratory. Clinicians often order T3 with TSH and free T4 so the hormones can be read as a group. Total T3 measures both bound and free hormone, while free T3 estimates the active portion; the choice depends on the clinical question.
T3 results are not interpreted alone. Conditions such as illness, pregnancy, and some medications can shift thyroid hormone levels, and total and free values can move differently. A qualified healthcare provider reviews the result with symptoms and the rest of the thyroid panel before drawing conclusions.
