Product Details
Free T3 is the biologically active form of thyroid hormone, responsible for regulating metabolism, temperature, and energy. Measuring free (unbound) T3 offers a more precise assessment of thyroid activity than total T3 alone.
This test helps evaluate thyroid dysfunction, especially when symptoms persist despite normal TSH or T4 levels, by giving insight into how your body converts T4 to the active T3 hormone.
