The Total T3 test measures the total amount of triiodothyronine (T3) in the blood, including both protein-bound and free hormone. T3 is an active thyroid hormone that plays a central role in regulating metabolism, energy levels, and body temperature.
This test is commonly used to help evaluate thyroid function, particularly in cases of suspected hyperthyroidism or abnormal thyroid hormone production. Total T3 results are often interpreted alongside TSH, Free T4, and Free T3 to provide a complete assessment of thyroid health.
