What does Triiodothyronine Free measure?
A Triiodothyronine Free test measures the levels of free triiodothyronine (T3), a hormone that is produced by the thyroid gland. T3 hormone plays an important 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 in the free form (not bound to proteins) and can be utilized by the body’s tissues, whereas more than 99% T3 is bound to proteins, such as albumin and thyroid-binding globulin (TBG), which prevent it from entering into the tissues. The body maintains a balance between bound and free T3 to ensure proper functioning.
