| thyroid releasing hormone | <endocrinology> Thyroid releasing hormone (TRH) is a byproduct of the hypothalamus and serves to stimulate the pituitary gland to produce thyroid stimulating hormone (TSH). TRH is produced by the hypothalamus when thyroid hormone (T3 and T4) blood levels are low. (27 Sep 1997) |

| thyrotropin-releasing hormone stimulation test | TRH stimulation test, a test of pituitary response to injection of thyrotropin-releasing hormone, which normally stimulates pituitary secretion of thyroid-stimulating hormone (TSH, thyrotropin), used primarily to distinguish pituitary from hypothalamic causes of thyroid disorders; TSH does not rise in cases of pituitary dysfunction, but does rise in cases of hypothalamic disorders.
