摘要: 目的分析生化分析仪与尿液分析仪检测尿液中直接胆红素(DBIL)、清蛋白(ALB)、葡萄糖(GLU)的一致性。方法收集2020年6月至12月住院患者的300份新鲜尿液标本，以DBIL、ALB、GLU为检测项目，分析生化分析仪(迈瑞BS-230/BS-240)与尿液分析仪(迈瑞OPM-1560A)的检测准确度及符合率，并进行Kappa一致性分析检验。结果2种分析仪检测尿液中DBIL、ALB、GLU的准确度均合格，符合率分别为97.8%、96.0%、99.3%，Kappa值分别为0.790、0.753、0.861。结论生化分析仪与尿液分析仪检测尿液中DBIL、ALB、GLU的一致性均较高，对于没有标准液的检测项目，生化分析仪可以替代尿液分析仪。Abstract: ObjectiveTo analyze the consistency of direct bilirubin(DBIL), albumin(ALB) and glucose(GLU) in urine by biochemical analyzer and urine analyzer.MethodsA total of 300 fresh urine specimens from inpatients in our hospital from June to December 2020 were collected, DBIL, ALB and GLU as the test items were analyzed by the automatic biochemical analyzer(Mindray BS-230/BS-240) and urine analyzer(Mindray OPM-1560A), and test accuracy and coincidence rate was analyzed using Kappa consistency analysis test.ResultsThe accuracy of the two analyzers for detecting DBIL, ALB and GLU in urine were all qualified. The coincidence rates were 97.8%, 96.0% and 99.3%, respectively, and the Kappa values were 0.790, 0.753 and 0.861, respectively.ConclusionThe consistency of DBIL, ALB and GLU in urine detected by biochemical analyzer and urine analyzer was relatively high. For testing items without standard solution, biochemical analyzer could replace urine analyzer.
