3种方法对尿液红、白细胞检出率的比较

Comparation of Three Examination Methods for Urine RBC and WBC

目的采用EH-2060A尿沉渣分析仪、Uritest-500B型尿干化学分析仪和尿沉渣镜检来检测尿液中的红细胞、白细胞并将其结果进行比较分析,探讨每种方法的检出率。方法收集1 000例尿液标本,分别用尿沉渣分析仪法、尿干化学分析法及尿沉渣镜检3种方法测出尿液红细胞、白细胞检出率,为临床检验工作提供参考。结果尿液采用Uritest-500B型尿干化学分析仪)进行检测,其红细胞检出率明显高于其他两种检测方法。而采用尿沉渣镜检和EH-2060A尿沉渣分析仪进行检测,其白细胞检出率却高于Uritest-500B型尿干化学分析仪,差异有统计学意义(P<0.05)。结论尿沉渣分析仪法、尿干化学分析法及尿沉渣镜检3种方法交叉互检,可排除假阳性和假阴性结果.可使尿液检验结果更准确,为临床提供可靠的诊断信息。

Objective To comparative analysis of three examination methods of urinary analyzer,dry chemical-method and urinary microscopic examination,to investigate merit,demerit and influential factors of each examination.Methods Collected 1 000 urinary examples.analyzed blood cells and leucocytes of urinary with EH-2060A urinary analyzer,Uritest-500B dry chemical method analyzer and microscopic examination respectively,in order to refer to clinical laboratory work.Results Compared to urinary sediment analyzer and microscopic examination.positive rate of dry chemical method was lower in leucocytes and higher in red blood cells.Conclusion Across examination with EH-2060A urinary sediment analyzer,dry chemical method and microscopic examination,can rule out false positive and negative examination results,Can supply more reliable diagnosis information for clinics.
