A TSH test measures the amount of thyroid stimulating hormone (TSH) in your blood. TSH is produced by the pituitary gland and tells the thyroid gland to make and release the hormones thyroxine (T4) and triiodothyronine (T3). See also: T3 test.
TSH (Thyroid Stimulating Hormone) is a hormone produced by the pituitary gland, and not by the thyroid as it may seem. The purpose of TSH is to stimulate the thyroid to produce more thyroid hormone. High TSH levels typically indicates that the body is not receiving enough thyroid hormone. A low TSH level is indicative of the body receiving too much thyroid hormone.
