不同检测方法在细菌性阴道炎临床诊断中的效能

Efficacies of different detection methods in clinical diagnosis of bacterial vaginitis

目的:观察pH值检测、胺试验、线索细胞检测和细菌性阴道炎(BV)快速检测在BV临床诊断中的效能。方法:选取196例疑似BV患者作为研究对象,均进行pH值检测、胺试验、线索细胞检测、BV快速检测和细菌培养试验,以细菌培养试验结果为金标准,比较pH值检测、胺试验、线索细胞检测和BV快速检测诊断BV的灵敏度和特异度。结果:细菌培养试验结果显示,196例疑似患者中,阳性135例,阴性61例;线索细胞检测和BV快速检测诊断BV的灵敏度均高于pH值检测、胺试验,差异有统计学意义(P<0.05);pH值检测、胺试验、线索细胞检测和BV快速检测诊断BV的特异度比较,差异无统计学意义(P>0.05)。结论:线索细胞检测和BV快速检测诊断BV的灵敏度高于pH值检测、胺试验。

Objective:To observe efficacies of pH detection,amine test,clue cell test,and rapid bacterial vaginosis(BV)test in clinical diagnosis of bacterial vaginitis.Methods:196196 patients with suspected BV were selected as the research objects,and pH test,amine test,clue cell test,rapid BV test,and bacterial culture test were performed.Using the results of bacterial culture test as the gold standard,the sensitivities and specificities of pH test,amine test,clue cell test and BV rapid test were compared.Results:The bacterial culture test results showed that among the 196 suspected patients,135 were positive and 61 were negative.The sensitivities of clue cell detection and rapid BV detection in the diagnosis of BV were higher than those of pH detection and amine test,and the differences were statistically significant(P<0.05).However,there were no statistically significant differences in the specificity of pH detection,amine test,clue cell detection,and rapid BV detection in the diagnosis of BV(P>0.05).Conclusions:The sensitivities of clue cell detection and rapid BV detection in the diagnosis BV are higher than pH detection and amine test.
