摘　　要：目的:探讨显微镜红细胞计数与尿液分析仪在尿液潜血检验中的价值。方法:选取2021年2月~2022年12月收治的102例接受尿液潜血检验的患者作为研究对象,依据《尿液检测的临床解读》为金标准,各患者均接受显微镜红细胞计数、尿液分析仪检验,对比检验结果。结果:102份标本依据《尿液检测的临床解读》作为金标准确诊85份阳性(83.33%)、17份阴性(16.67%)。显微镜红细胞计数确诊率80.39%、敏感度92.94%、特异度17.65%、阳性预测值89.77%、阴性预测值33.33%与尿液分析仪确诊率79.41%、敏感度90.59%、特异度23.53%、阳性预测值89.53%、阴性预测值36.36%比较,差异无统计学意义(P>0.05)。结论:任意方式进行尿液潜血检验均无法确保检验结果准确率达百分之百,此次分析显微镜红细胞计数、尿液分析仪两种方式检验准确性基本相当,但前者准确性略高,为降低漏诊、误诊率,临床需结合显微镜红细胞计数、尿液分析仪两种方式进行检验,确保检验结果有权威性和指导性。Objective:To explore the value of microscope red blood cell count and urine analyzer in urine occult blood test.Methods:102 patients who received urine occult blood test from February 2021 to December 2022 were selected as the research objects.According to the“Clinical Interpretation of Urine Test”as the gold standard,all patients were tested by microscope red blood cell count and urine analyzer,and the test results were compared.Results:According to the“Clinical Interpretation of Urine Testing”as the gold standard,85 specimens were confirmed as positive(83.33%)and 17 specimens were negative(16.67%).The diagnostic rate of microscope red blood cell count was 80.39%,sensitivity was 92.94%,specificity was 17.65%,positive predictive value was 89.77%,negative predictive value was 33.33%,and the diagnostic rate of urine analyzer was 79.41%,sensitivity was 90.59%,specificity was 23.53%,positive predictive value was 89.53%,negative predictive value was 36.36%,and the difference was not statistically significant(P>0.05).Conclusion:Urine occult blood test in any way can not ensure the accuracy of the test results to reach 100%.This time,the accuracy of the analysis microscope red blood cell count and urine analyzer is basically the same,but the accuracy of the former is slightly higher.In order to reduce the rate of missed diagnosis and misdiagnosis,the clinical needs to combine the microscope red blood cell count and urine analyzer to test,so as to ensure that the test results have authority and guidance.
