Total T4 (Thyroxine) Test

Thyroid Tests




A Total T4 test is a blood test that measures the total amount of thyroxine, a hormone produced by the thyroid gland, in the bloodstream. Thyroxine plays a role in controlling the body's metabolism and energy levels. Abnormal levels of total T4 can indicate thyroid disorders such as hyperthyroidism or hypothyroidism. This test is often ordered along with other thyroid function tests to help diagnose and monitor thyroid conditions.
