Effect of Urine Dry Chemical Analyzer Combined with Urine Sediment Analyzer in Urine Red Blood Cell Test
Objective:To study the clinical application value of urine dry chemical analyzer combined with urine sediment analyzer in urine red blood cell examination.Methods:100 patients who received urine red blood cell examination in our hospital from May 2021 to May 2023 were selected as the main subjects.All patients were examined by microscope,urine dry chemical analyzer and urine sediment analyzer.The results of microscope examination were taken as the gold standard.The diagnostic results of urine dry chemical analyzer alone,urine sediment analyzer alone,urine dry chemical analyzer combined with urine sediment analyzer were calculated.Results:The diagnostic accuracy of urine dry chemical analyzer combined with urine sediment analyzer was significantly higher than that of urine dry chemical analyzer and urine sediment analyzer alone,which had statistical significance(P<0.05).The missed diagnosis rate of dry chemical analyzer combined with urine sediment analyzer was significantly lower than that of urine dry chemical analyzer and urine sediment analyzer alone,which had statistical significance.The diagnostic specificity,sensitivity and accuracy of urine dry chemical analyzer were 94.00%,92.00%and 93.00%respectively.The diagnostic specificity,sensitivity and accuracy of urine sediment analyzer were 93.00%,91.00%and 92.50%respectively.The diagnostic specificity,sensitivity and accuracy of urine dry chemical analyzer combined with urine sediment analyzer were 99.00%,98.00%and 98.50%respectively.Conclusion:In the urine red blood cell test,urine dry chemical analyzer combined with urine sediment analyzer has obvious advantages,ensuring the accuracy and reliability of test results,reducing the risk of misdiagnosis and missed diagnosis.
