The Total T4 test measures the total amount of thyroxine (T4) in the blood, including both protein-bound and free hormone. T4 is the main hormone produced by the thyroid gland and plays a key role in regulating metabolism and energy balance.
This test is commonly used to evaluate thyroid function and help identify thyroid disorders such as hypothyroidism or hyperthyroidism. Total T4 results are often interpreted alongside TSH, Free T4, and thyroid-binding proteins to provide a more complete assessment of thyroid health.
