Total T4 (Thyroxine)


The total thyroxine test is employed to identify thyroid conditions. The test determines your blood's level of the thyroid hormone thyroxine (T4). Both too little and too much T4 have been linked to various thyroid disorders. A blood test denoted as thyroxine test aids in the diagnosis of thyroid disorders. The thyroid is a little butterfly-shaped gland located at the base of your neck. The hormones your thyroid generates, regulate how your body consumes energy. These hormones affect your mood, muscular mass, weight, heart rate, and body temperature. In children, thyroid hormones affect growth, too. This test is also known as a thyroxine screen, total T4 concentration, and total T4 test.
