Comparison of Gram Stain and Pap Smear Procedures in theDiagnosis of Bacterial Vaginosis

[摘要] Objective:The purpose of this study was to examine the characteristics of Gram stain versus Pap smear indiagnosis of bacterial vaginosis (BV).Methods:One-thousand and sixty women were enrolled in this study. All cases with symptoms of BV weredetermined by Amsel's criteria, which were accepted as the gold standard for diagnosis of BV. Pap smear andGram stain evaluations were compared according to Amsel's criteria, without viewing the clinical results of thepatients. Gram stain and Pap smear results were determined as negative or positive according to Amsel’s criteria.Sensitivity, specifity and positive predictive values were calculated.Results:After accepting the cases that were diagnosed as BV according to Amsel's criteria as reference cases, thesensitivity of the Gram stain method was calculated as 97% and the sensitivity of the Pap smear method as 93%.Similar specificity rates were obtained with both methods in diagnosis of BV related to the clinical results. Therewere no statistically significant differences in diagnosis of BV between these two groups.Conclusion:If Amsel's criteria are accepted as the gold standard for diagnosis of BV, Gram stain and Pap smearmethods will give similar results in diagnosis.
