Clinical value of quantitative bacterial count combined with urinary sediment white blood cell test in the diagnosis of urinary tract infection
Objective To explore the clinical value of quantitative bacterial count combined with urinary sediment white blood cell test in the diagnosis of urinary tract infection.Methods A total of 85 patients with suspected urinary tract infections were selected as research samples.The results of urine bacterial culture test were taken as the gold standard.Quantitative bacterial count,urinary sediment white blood cell test and combined test were carried out on the patients to compare the test results.Results Urine bacterial culture test results of 85 suspected urinary tract infection patients were taken as the gold standard,with 83 positive cases and 2 negative cases.Quantitative bacterial count test was positive in 76 cases and negative in 9 cases;urinary sediment white blood cell test was positive in 75 cases and negative in 10 cases.There were 83 positive cases and 2 negative cases in the combined diagnosis.The diagnostic compliance rate of the combined test was 97.65%and the sensitivity was 98.80%,which were higher than that of quantitative bacterial count(89.41%,90.36%)and urinary sediment white blood cell test(88.24%,89.16%),and there was a difference(P<0.05).There was no difference in the comparison of diagnostic compliance rate and sensitivity of quantitative bacterial count and urinary sediment white blood cell test(P>0.05).No difference was seen in the comparison of the specificity of quantitative bacterial count,urine sediment leukocyte test and the combined test(P>0.05).Conclusion Quantitative bacterial count combined with urinary sediment white blood cell test has a high accuracy for urinary tract infection,which can reduce the interference of various factors on diagnosis,provide a good basis for the diagnosis and treatment of patients,and help patients to diagnose the diseases in time,with significant clinical application value.
