Abstract Objective To explore the value of urinary sediment microscopic examination and urine routine dry chemical method in routine urine examination.Methods A total of 340 urine samples admitted to Shenyang Fifth People′s Hospital from January 2018 to January 2020 were selected as the research subjects, microscopic examination of urinary sediment, routine dry chemistry and the combination of the two methods were performed.The positive rates of white blood cell, urine protein and red blood cell of the three detection methods were compared.Results There were no significant differences in the sensitivity, specificity and accuracy between microscopic examination of urinary sediment and routine dry chemical method (P>0.05).The sensitivity, specificity and accuracy of the combined detection of the two methods were higher than those of the single method, and the differences were statistically significant (P<0.05).The positive rate of quantitative leukocyte in urine dry chemistry test was lower than that in urine sediment microscopic examination, and the positive rate of quantitative erythrocyte in urine sediment microscopic examination was higher than that in urine sediment microscopic examination, and the differences were statistically significant (P<0.05).Quantitative leukocyte positive rate and quantitative erythrocyte positive rate of combined detection were higher than those of urine routine dry chemical method and urinary sediment microscopic examination, the differences were statistically significant(P<0.05).Conclusion Both urine sediment test and routine dry chemical urine test have clinical testing value, and the combined application of the two detection methods is more effective in reducing the probability of missed diagnosis and misdiagnosis, and improving the level of clinical testing.
