Disclosed is a method for the determination of creatinine in urine which involves contacting a urine test sample with a reagent system containing Cu+2, a hydroperoxide and an oxidizible dye which provides a detectable response when oxidized in the presence of a pseudoperoxide. The reagent system also includes a buffer to maintain the urine's pH within the range of 6.6 to 8.0 and a chelating agent for the cupric ions to prevent oxidation of the dye in the absence of creatinine.
本发明公开了一种测定尿液中
肌酐的方法,该方法是将尿液检测样本与含有 Cu+2、
过氧化氢和可氧化
染料的试剂系统接触,当
染料在假过氧化物存在下被氧化时,会产生可检测的反应。试剂系统还包括一种缓冲剂,用于将尿液的 pH 值保持在 6.6 至 8.0 的范围内,以及一种
