Thyroid Profile

This test measures the level of thyroxine (T4) in your blood and calculates how much of this hormone is active and available for your body to use. It helps show whether your thyroid gland is working properly to control your metabolism, which affects your energy and weight. This profile helps rule out conditions where the thyroid is either overactive or underactive. However, it does not identify the specific underlying cause of the thyroid issue, such as an autoimmune disease, without additional testing.
