Abstract

This present study was conducted to validate diagnostic tests of BV in 290 women in National Hospital of Dermatology and Venereology, Amsel’s criteria and Nugent scoring system were used to diagnose BV. Nugent scoring system was considered the gold standard and sensitivity, specificity, positive predictive value and negative predictive value of Amsel’s criteria were compared with those of Nugent scoring system. Results: Kappa coefficient was used to assess the diagnostic value of Nugent scoring system and Amsel’s criteria. Kappa coefficient was found 0.81, which confirms the reliability of both diagnostic methods. As compared to Nugent scoring system, Asmel’s criteria enjoy sensitivity of 85.5%, specificity of 96.1%, positive predictive value of 85.5%, negative predictive value of 96.1%. Conclusion: Amsel’s criteria shows good agreement with the gold standard method of Nugent et al. and can be used as an alternative to Nugent’s criteria for diagnosis of BV.
