TOTAL TRIIODOTHYRONINE (T3)

The total triiodothyronine (T3) test measures the level of T3, a thyroid hormone, in the blood. T3 is involved in regulating metabolism, growth, and development. This test is used to evaluate thyroid function, diagnose thyroid disorders, and monitor hormone replacement therapy. Elevated total T3 levels can indicate hyperthyroidism, while low levels suggest hypothyroidism. The total T3 test provides valuable information for assessing thyroid health, diagnosing underlying conditions, and guiding treatment decisions to manage thyroid hormone levels effectively.
