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 Range. The function of thyroid stimulating hormone (or TSH) is to regulate the normal levels of thyroid hormones in the body. It is a peptide hormone secreted by the thyrotrope cells of anterior pituitary gland. The TSH activates the thyroid gland to produce both Triiodothyronine(T3) and thyroxine (T4) hormones. It is suggestive of the development of resistance to thyroid hormone. 2  Above normal TSH range is also evident in veterinary doctors or laboratory workers, who are exposed to mice. 3  High TSH range is a warning sign of Cretinism.
