FREE TRIIODOTHYRONINE (FT3)

The free triiodothyronine (FT3) test measures the level of free triiodothyronine, a thyroid hormone, in the blood. FT3 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 FT3 levels can indicate hyperthyroidism, while low levels suggest hypothyroidism. The FT3 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.
