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.
Thyroid Stimulating Hormone (TSH) TSH (also known as thyrotropin) is a glycoprotein consisting of: a beta chain of 118 amino acids and. an alpha chain of 92 amino acids. The alpha chain is identical to that found in two other pituitary hormones, FSH and LH as well as in the hormone chorionic gonadotropin.
