Test Details: Free Thyroid profile helps to diagnose and monitor thyroid gland disorders. This test measures the free active component of T3 and T4 hormones along with TSH, and hence reflects its accurate function in the body. As use of TSH alone may be misleading in case of thyroid disorders, this test proves highly beneficial when suspected with thyroid disorder related symptoms such as fatigue, weight gain or loss, tremors, hair loss, menstrual irregularities, etc.
