本文仅介绍一些临床上实用的肾功能检查及其临床意义,至于具体的操作方法,请参考有关检验学书籍。每一个肾单位由肾小球和肾小管2个部分组成,故肾功能检查亦相应地分为二类。一、肾小球功能检查法肾小球的主要功能是滤过,故肾小球滤过率(GFR)是肾小球功能的代表。目前认为,内生肌酐清除率(Ccr)是肾小球滤过率的临床最佳指标,菊粉清除率虽然比较准确,但由于测定技术上比较困难,而且菊粉价格昂贵,故临床上实用价值不大。目前仍有一些单位在使用尿素清除率,此种检查并不比肌酐清除率
This article describes only some of the clinical and practical renal function tests and clinical significance, as for the specific method of operation, please refer to the books on the test. Each nephron by the glomerular and tubular 2 parts, so renal function tests are also divided into two categories. First, the glomerular function test The main function of glomerular filtration, glomerular filtration rate (GFR) is a representative of glomerular function. At present that endocrine creatinine clearance rate (Ccr) is the best clinical indicators of glomerular filtration rate, although the inulin clearance rate more accurate, but because of the determination of the technical difficulties, and inulin expensive, it is clinically useful Little value. There are still some units in the use of urea clearance rate, this test is not less than creatinine clearance
