thy·ro·tro·pin (thr-trpn, th-rtr-) or thy·ro·tro·phin (-fn)

n.

A glycoprotein hormone secreted by the anterior lobe of the pituitary gland that stimulates and regulates activity of the thyroid gland. Also called thyroid-stimulating hormone, thyrotropic hormone.

thyrotropin

a hormone secreted by the anterior lobe of the pituitary gland that has an affinity for and specifically stimulates the thyroid gland. Called also thyroid-stimulating hormone (TSH).

---

thyrotropin releasing hormone (TRH)

a tripeptide produced in the hypothalamus and released into the hypothalamohypophyseal portal circulation to reach the adenohypophysis where it triggers the release of thyroid-stimulating hormone. Called also TSH releasing factor, TSH releasing hormone.

thyrotropin releasing hormone stimulation test, response test

measures serum levels of thyrotropin-stimulating hormone (TSH) before and after administration of TRH.

thyrotropin-stimulating hormone (TSH) stimulation test, response test

measurement of serum levels of thyroid hormone(s) (T₃ and/or T₄) before and after the administration of TSH is a more reliable indicator of the functional capacity of the thyroid glands than single determinations and may distinguish between primary and secondary hypothyroidism.
