The Thyroid Stimulating Hormone (TSH) test is a blood test that measures the levels of TSH in the body. TSH is a hormone produced by the pituitary gland that stimulates the thyroid gland to produce and release thyroid hormones. The TSH test is used to diagnose and monitor thyroid conditions, such as hypothyroidism and hyperthyroidism. In general, a high TSH level indicates an underactive thyroid, while a low TSH level indicates an overactive thyroid. However, the interpretation of TSH test results is complex, and it’s important to consult with a healthcare provider to determine the appropriate course of action.
