FREE THYROXINE (FT4)

The free thyroxine (FT4) test measures the level of free thyroxine, a thyroid hormone, in the blood. FT4 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 FT4 levels can indicate hyperthyroidism, while low levels suggest hypothyroidism. The FT4 test is valuable for assessing thyroid health, diagnosing underlying conditions, and guiding treatment decisions to manage thyroid hormone levels effectively. It provides important information for maintaining overall health and preventing complications associated with thyroid dysfunction.
