Objective: To evaluate the accuracy of liquid-based cytology (SurePathTM) for diagnosing bacterial vaginosis. Methods: A cross-sectional study was realized in 413 women with liquid- based cytology (SurePathTM) and Gram bacterioscopy of vaginal sample and Nugent score. The results of cytology in liquid medium and the result of bacterioscopy were compared using bacterioscopy as the gold standard for the study of sensitivity, specificity, predictive values, and accuracy, and the Kappa index was applied for a 95% confidence interval. Results: The women studied were, on average, 35.9 years old (+10.3), and with an average number of pregnancies of 1.5 (+1.4). Cite the number of cases of normality, intermediate flora, and BV (absolute and percentage). Liquid-based cytology showed sensitivity for the diagnosis of normality and bacterial vaginosis of 66% and 92.2%, respectively, the specificity of 99.6% and 97%, respectively. The accuracy for normality and BV was 85.5% and 95.3%, respectively. The Kappa index, the agreement index, between the methods was 0.935 for bacterial vaginosis (almost perfect agreement). Conclusion: Liquid-based cytology of the SurePathTM type has high accuracy and agreement with the Gram-stained vaginal bacterioscopic examination with the Nugent score for the diagnosis of bacterial vaginosis.
