TOTAL THYROXINE (T4)

The total thyroxine (T4) test measures the level of T4, a thyroid hormone, in the blood. T4 plays a crucial role in regulating metabolism, growth, and development. This test is used to evaluate thyroid function, diagnose thyroid disorders, and monitor hormone replacement therapy. Elevated total T4 levels can indicate hyperthyroidism, while low levels suggest hypothyroidism. The total T4 test provides valuable information for assessing thyroid health, diagnosing underlying conditions, and guiding treatment decisions to manage thyroid hormone levels effectively.
