__项目介绍 :__\\
  本试验同时测定血液和尿液中的肌酐含量以评估肾小球滤过功能。肌酐是肌酸分解代谢的产物,肌酸是肌肉用来储存和转换能量的含氮有机化合物。机体内肌酐量的多少取决于肌肉量,体内肌酐量产生恒定。当血液通过肾脏时,肌酐通过肾脏滤过单位肾小球滤出血液,血液滤出的肌酐量取决于肾小球滤过功能和肾血流量。如果肾小球损伤或血流量减少,将导致血液中的肌酐滤出减少,进而导致尿液肌酐减少。\\

  矫正肌肉量(用体重)的影响后,反映肾小球滤过率,是评价肾小球功能的有用指标。
  肌酐清除率是用来评估肾脏滤过率和滤过功能的实验,也可用于检查肾功失调和/或肾脏血流减少。对于患有慢性肾脏疾病或充血性心力衰竭的患者,肌酐清除率有助于病情进展的监测和严重程度评估。\\
__何时检测:__\\ 
 当需要了解肾脏滤过功能时应选用本实验。对于已明确诊断或怀疑肾功失调的血肌酐水平升高患者,以及肾脏血流量减少(如充血性心力衰竭)的情况时,应考虑选用本实验。
