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.
What is TSH? TSH (Thyroid Stimulating Hormone) is a hormone that is produced by the pituitary gland; it is the job of the TSH to stimulate the thyroid and trigger the production of thyroid hormone. High TSH signifies that your thyroid is not producing enough hormone; a low TSH denotes an overproduction of thyroid hormone.
