Understanding Triiodothyronine Free in Navi Mumbai

What is Triiodothyronine Free in Navi Mumbai?

A Triiodothyronine Free test measures the level of free triiodothyronine (FT3) hormone in the blood. This test helps assess overall thyroid function and detect possible thyroid disorders. It is also performed in combination with free T4 and TSH tests as part of a thyroid profile free test.

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.
