To evaluate the accuracy of Amsel's criteria individually or in combinations of two for the clinical diagnosis of bacterial vaginosis.
This cross-sectional study enrolled 135 women at UNICAMP, and evaluated Amsel's four clinical criteria. Sensitivity, specificity, positive and negative predictive values were calculated for each criterion individually, in combinations of two, and for the classic test with at least three criteria present. The Nugent method was used as gold standard.
The most sensitive individual criteria were pH and vaginal discharge (97%), the latter having lowest specificity (26%). The criterion with highest specificity was the presence of clue cells (86%). The combination of two criteria showed sensitivity of 83% to 93%, and specificity of 82% to 94%.
The accuracy of Amsel's clinical criteria individually or in combinations of two was as accurate as the presence of at least three criteria for the diagnosis of bacterial vaginosis.
评估单独使用或两两组合使用阿姆斯勒标准对细菌性阴道病进行临床诊断的准确性。
这项横断面研究纳入了坎皮纳斯大学的135名女性，并对阿姆斯勒的四项临床标准进行了评估。分别计算了每项标准、两项标准组合以及存在至少三项标准的经典检测的敏感性、特异性、阳性预测值和阴性预测值。纽金特方法被用作金标准。
最敏感的单项标准是pH值和阴道分泌物（97%），后者特异性最低（26%）。特异性最高的标准是线索细胞的存在（86%）。两项标准组合的敏感性为83%至93%，特异性为82%至94%。
单独使用或两两组合使用阿姆斯勒临床标准对细菌性阴道病进行诊断的准确性与存在至少三项标准时相同。
