Understanding Triiodothyronine Total in Mohali
What is Triiodothyronine Total in Mohali?
A Triiodothyronine Total measures the level of total triiodothyronine hormone in the blood. This test helps assess overall thyroid function and detect possible thyroid disorders. It is also performed in combination with total T4 and TSH tests as part of a thyroid profile total test.
What does Triiodothyronine Total measure?
A Triiodothyronine Total measures triiodothyronine, also known as T3, 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. Free T3 is not bound to proteins in the blood and is the active form of T3. Whereas, bound T3 is bound to proteins, such as albumin and thyroid hormone binding globulin (THBG), which prevent it from entering the body tissues.
