Abstract
To compare the performance of the Amsel criteria, culture of Gardnerella spp., and wet mount microscopy (WMM) in the diagnosis of bacterial vaginosis.
Results
The sensitivity and specificity for the different approaches were: Amsel criteria 41.3% (95% confidence interval [CI] 33.76–49.18) and 97.8% (95% CI 96.21–98.81); cultures 59.9% (95% CI 51.47–67.85) and 99.0% (95% CI 97.76–99.69); WMM 82.6% (95% CI 76.02–88.05) and 92.4% (95% CI 89.98–94.45), respectively. WMM performed equally well in symptomatic and asymptomatic women. Amsel criteria in scenarios where there is no use of a microscope had very poor sensitivity (22.8% [CI 16.63–29.87%]).
