促甲状腺激素释放激素(TRH)由下丘脑分泌,调节着垂体前叶释放TSH,也影响催乳激素和生长激素的分泌。静脉注射TRH随后测定TSH水平,可用来协助诊断和估价越来越多的内分泌疾病。这项试验的副作用一般都很轻微和短暂,如恶心、发热感、尿意频、头痛等,偶有血压升高,但不伴有危重表现。 Thyrotropin releasing hormone (TRH) is secreted by the hypothalamus and regulates the release of TSH from the anterior pituitary. It also affects the secretion of prolactin and growth hormone. Intravenous TRH followed by determination of TSH levels can be used to assist in the diagnosis and evaluation of an increasing number of endocrine disorders. The side effects of this test are generally mild and transient, such as nausea, fever, urinary frequency, headache, occasional blood pressure, but not associated with critical performance.
