Total T4 Test
About the Total T4 Test
The Total T4 Test is a primary blood test that measures the total amount of thyroxine (T4) in your bloodstream. Thyroxine is the main hormone produced by the thyroid gland and is essential for regulating your body’s metabolism, energy levels, and growth. This test measures both the T4 that is bonded to proteins and the “free” T4 that is available for your tissues to use. Doctors frequently recommend this test to screen for thyroid disorders, monitor the effectiveness of thyroid-related medications, and evaluate the function of the pituitary gland. Identifying abnormal T4 levels is crucial for diagnosing both hyperthyroidism and hypothyroidism.
