Three vaginal infections are frequent causes of vaginal discharge: (1) bacterial vaginosis, (2) vulvovaginal candidiasis, and (3) Trichomoniasis. Simple tool like pH and Whiff test can be carried out without any expertise. This study was carried out to evaluate sensitivity and specificity of pH test and Whiff test individually and in combination in diagnosis of abnormal vaginal discharge, considering microscopy as gold standard. Material and methods: This prospective observational cross sectional study includes 189 women of reproductive age group with vaginal discharge attending OBGY clinic from September 2010 to May 2012. Both pregnant and non-pregnant women were included in the study with chief complaint of vaginal discharge. Vaginal discharge were collected for determining pH, to perform Whiff test and for Gram staining and microscopy. Results: Of 189 women 86 (45.5%) were diagnosed to have bacterial vaginosis by applying Nugent__ampersandsignrsquo;s criteria as a gold standard. Vulvovaginal candidiasis and Trichomoniasis was found in 61(32.27%) and 24(12.69%) respectively. The pH ? 4.5 was recorded in 136 (71.95%) and Whiff test positive in 120 (63.49%) of women with abnormal vaginal discharge. Conclusion: Simple tools like pH test and Whiff test can be used as a reliable test for determining abnormal vaginal discharge.
