# Thyroid-stimulating Hormone (TSH) and Free T4

> This test measures levels of thyroid-stimulating hormone (TSH) and free T4 to evaluate how well your thyroid gland is functioning. It helps show whether your body has the right amount of hormone to regulate energy and metabolism, which is important if you have symptoms like fatigue or unexplained weight changes. These results help doctors distinguish between an underactive thyroid (hypothyroidism) and an overactive thyroid (hyperthyroidism). However, this test alone does not identify the specific underlying cause of the thyroid issue, such as an autoimmune disorder.
