About the Triiodothyronine Hormone T3 Test
This blood test evaluates triiodothyronine (T3), one of the two main hormones made by the thyroid gland. T3 is the more biologically active hormone and acts on cells to regulate metabolism, heart rate, energy use, and body temperature. T3 travels in the blood both bound to proteins and free; measuring total T3 captures both fractions, while free T3 captures the active portion. The test is used to help determine abnormal thyroid function and to look for T3-related abnormalities, often alongside TSH and T4. Results are interpreted by a healthcare provider using the pattern across the thyroid panel and the clinical picture.

Understanding your results
T3 is compared against a reference range and interpreted with TSH and T4. A high T3 can accompany an overactive thyroid, while a low level may occur with illness or reduced conversion from T4. Because total and free T3 can tell slightly different stories, the ordering provider chooses which is most useful. A healthcare provider should interpret the result with your symptoms and any additional testing.
