Abstract：Objective To establish a re-examination rule for the automatic urine analysis workstation consisting of Derry H-800 urine dry chemical analyzer and IRIS IQ-200 urine forming analyzer,and to verify the application of this rule in the clinic.Methods A total of 1715 specimens were tested by using this workstation.At the same time,each specimen was examined by urine sediments microscopic examination.Through the analysis of the test results of two methods,re-examination rules of the laboratory′s urine analysis workstation were developed and validated with 300 specimens.Results The results of the microscopic examination were taken as standards based on the examination of 1715 specimens.The false negative rate of the test results of urine analysis workstation was 1.22%,the false positive rate was 2.97%,and the re-examination rate was 33.41%.The results of the clinical specimen validation by the application of the re-examination rules were as follows:the false negative rate was 1.33%,the false positive rate was 1.66%and the re-examination rate was 35.33%.Conclusion The laboratory has developed and validated the re-examination rules for automated urine analysis workstation.The false negative rate,false positive rate and re-examination rate all can meet the requirements.This re-examination rule can be applied in clinical practice.
