Objective:To analyze the application effect of urine dry chemical analyzer combined with urine sediment analyzer in urine red blood cell examination.Methods:A total of 200 patients who underwent routine urine examination in our hospital from May 2022 to May 2023 were selected as study samples,and their mid-stream urine samples from morning were taken as test specimens.Urine dry chemical analyzer(test group 1),urine sediment analyzer(test group 2),and urine dry chemical analyzer combined with urine sediment analyzer(test group 3)were respectively tested.Urinary sediment microscopy was the gold standard for diagnosis.The results of the three methods were compared.Results:①In this examination,180 cases were positive and 20 cases were negative,accounting for 90.00%and 10.00%respectively;160 cases were positive and 40 cases were negative by urine dry chemical analyzer,accounting for 80.00%and 20.00%respectively.There were 172 cases positive and 28 cases negative by urine sediment analyzer,accounting for 86.00%and 14.00%respectively.175 cases were positive and 25 cases were negative,accounting for 87.50%and 12.50%respectively.②After comparison,the specificity and accuracy of test group 3 were higher than those of test group 1,and the rate of missed diagnosis was lower than that of test group 1,P<0.05.The sensitivity and specificity of test group 2 were higher than those of test group 1,and the rate of missed diagnosis was lower than that of test group 1(P<0.05).There was no significant difference between test group 2 and test group 3.Conclusion:The combination of urine dry chemical analyzer and urine sediment analyzer can improve the specificity,sensitivity and accuracy of urine red blood cell test to a certain extent,and reduce the rate of missed diagnosis.
