Detecting red blood cells in a patient's urine by placing an aliquot of the urine in an automated analyzer sampling cup. The urine is transferred to a cuvette mounted within the automated analyzer and one or more reagent compositions in an aqueous medium is injected into the cuvette. The reagent contains a buffer to adjust pH, chemicals to remove substances in the urine that interfere with colorimetric photometry, a compound to lyse the red blood cells in the urine, a substrate to react with the hemoglobin, a color indicator and a surfactant to improve fluid mechanics. The sample is read against a standard using a pre-programmed monochromatically specified wavelength to determine the presence or absence of blood cells in the patient's urine.
将等量尿液放入自动分析仪采样杯中,检测病人尿液中的红细胞。将尿液转移到安装在自动分析仪内的比色皿中,然后将水介质中的一种或多种试剂成分注入比色皿。试剂中含有调节 pH 值的缓冲液、去除尿液中干扰比色光度法的物质的化学物质、溶解尿液中红细胞的化合物、与血红蛋白反应的底物、颜色指示剂和改善流体力学的表面活性剂。使用预先设定的单色指定波长,对照标准读取样本,以确定患者尿液中是否存在血细胞。
