尿液潜血检验中尿液分析仪、显微镜红细胞计数的应用效果探究

Research on the practical effect of urine analyzer and microscope red blood cell count in urine occult blood test

目的分析尿液潜血检验中尿液分析仪、显微镜红细胞计数的应用效果。方法90份进行尿液检验分析患者的尿液标本,分别进行显微镜红细胞计数检验与尿液分析仪检验,观察两种方法的检验结果,以显微镜红细胞计数检验结果为金标准,分析尿液分析仪检验的敏感度、特异度、误诊率、漏诊率。结果显微镜红细胞计数检验阳性20例,阴性70例,阳性率为28.57%(20/70)。尿液分析仪检验阳性23例,阴性67例,阳性率为25.56%(23/90)。以显微镜红细胞计数检验结果为金标准,尿液分析仪检验的敏感度为85.00%(17/20),特异度为91.43%(64/70),误诊率为8.57%(6/70),漏诊率为15.00%(3/20)。结论尿液分析仪检验及显微镜红细胞计数检验方法各有优点与不足,临床检验期间应以患者实际状况为依据,选择相应的检验方法,若条件允许,可联合两种检验方法,从而提高临床检验结果的准确率,值得临床进一步采纳与推广。

Objective To analyze the practical effect of urine analyzer and microscope red blood cell count in urine occult blood test.Methods 90 urine samples were tested by microscope red blood cell count and urine analyzer respectively.The sensitivity,specificity,misdiagnosis rate and missed diagnosis rate of urine analyzer were analyzed with the results of microscopic red blood cell count as the gold standard.Results Microscopic red blood cell count tested positive in 20 cases and negative in 70 cases,the positive rate was 28.57%(20/70).Urine analyzer tested positive in 23 cases and negative in 67 cases,the positive rate was 25.56%(23/90).Taking the microscope red blood cell count test result as the gold standard,the sensitivity of the urine analyzer was 85.00%(17/20),the specificity was 91.43%(64/70),the misdiagnosis rate was 8.57%(6/70),and the missed diagnosis rate was 15.00%(3/20).Conclusion Both the urine analyzer test and the microscope red blood cell count test method have their own advantages and disadvantages.During the clinical test,the corresponding test method should be selected based on the actual condition of the patient.If conditions permit,the two test methods can be combined to improve the accuracy of clinical test results,which is worthy of further clinical adoption and promotion.
