Free-T3 (Tri-iodothyronine)
Overview
A T3 (Triiodothyronine) test is utilized to identify issues with the thyroid gland. Triiodothyronine (T3) travels throughout the body while attached to thyroxine-binding globulin and albumin in circulation. Only a small percentage, less than 0.3%, of the entire T3 is in the free form known as FT3, which is the form that is active. T3 is one of the two key thyroid hormones that are vital. A blood sample will be taken by a healthcare provider to analyze T3 levels.
Triiodothyronine is typically found in two forms: free T3 and bound T3. A T3 test that is free helps to assess if thyroid replacement treatment is functioning properly. It can also assist in identifying irregularities associated with proteins that attach to various thyroid hormones. Free T3 is a thyroid function test that is either second or third-level in terms of importance. It is utilized to confirm hyperthyroidism.
