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.
