摘要
目的:分析在尿路感染患者的筛查中应用多指标联合检测的临床意义。方法:2018年8月-2020年8月收治疑似尿路感染患者78例,采集患者尿液标本,对标本中的亚硝酸盐、白细胞酯酶以及细菌计数进行检测,分析检测结果;以细菌培养结果作为金标准,分析不同指标诊断尿路感染患者的特异度、灵敏度、阴性预测值及阳性预测值。结果:78例疑似尿路感染患者经细菌培养法确诊为阳性30例,三种指标联合检测的灵敏度最高;三种指标联合检测结果高于单独检测及两项联合检测结果,差异有统计学意义(P<0.05)。结论:亚硝酸盐、白细胞酯酶以及细菌计数联合检测的诊断准确率较高,可为临床诊断尿路感染患者提供参考。
Objective:To analyze the clinical significance of multi-index combined detection in the screening of patients with urinary tract infection.Methods:From August 2018 to August 2020,78 patients with suspected urinary tract infection were selected to our hospital.Urine samples were collected,and nitrite,leukocyte esterase and bacterial count in the samples were detected,and the detection results were analyzed.With the results of bacterial culture as the gold standard,the specificity,sensitivity,negative predictive value and positive predictive value of different indicators in the diagnosis of urinary tract infection were analyzed.Results:Among 78 suspected patients with urinary tract infection,30 cases were confirmed positive by bacterial culture method,and the sensitivity of the combined detection of the three indicators was the highest.The results of the combined detection of the three indicators were significantly higher than the single detection and the combined detection of the two indicators,the differences were statistically significant(P<0.05).Conclusion:The combined detection of nitrite,leucocyte esterase and bacterial count has a high diagnostic accuracy,which can provide reference for clinical diagnosis of urinary tract infection.
