What Is a Free T3 Test?

The Free T3 Test is a blood test that measures the level of free, unbound triiodothyronine (T3) in your bloodstream. T3 is one of the main thyroid hormones that helps regulate your metabolism, energy levels, and body temperature. Most of the T3 in your body is attached to proteins, but a small portion remains free and biologically active.

This test measures that free portion to give a clear picture of your thyroid’s active hormone levels.

Doctors often order the Free T3 Test along with the TSH (Thyroid Stimulating Hormone) and Free T4 tests to evaluate thyroid function, diagnose thyroid disorders such as hyperthyroidism, or monitor ongoing thyroid treatments.
