What does FT3 & FT4 (Free T3 & Free T4) measure?
Contains 2 testsAn FT3 & FT4 (Free T3 & Free T4) test measures the free form of triiodothyronine (FT3) and thyroxine (FT4) hormones made by the thyroid gland. These hormones exist in the blood in two forms: bound (attached to proteins) and free (not attached to proteins). Most of the T3 and T4 hormones circulating in the blood are bound to proteins and only a small part circulates freely and constitutes the physiologically active form. The body maintains a delicate balance of bound and free T3 as well as T4 to ensure proper functioning. Measuring free forms of thyroid hormones (FT3 and FT4) gives a better understanding of thyroid function than the bound forms as they are independent of changes in the concentration and the binding properties of the thyroid hormone binding proteins.

Triiodothyronine Free
The Triiodothyronine Free test measures the levels of free triiodothyronine (T3), a hormone produced by the thyroid gland. T3 hormone plays a vital role in regulating the body's metabolism, energy levels, and growth & development. It exists in the blood in two forms: free T3 and bound T3. Only a small portion of T3 is free (not bound to proteins) and can be utilized by the body’s tissues. In contrast, more than 99% of T3 is bound to proteins, such as albumin and thyroid-binding globulin (TBG), preventing it from entering the tissues. The body balances bound and free T3 to ensure proper functioning.
