Abstract:
The signs and symptoms of trichomonasis vaginalis are not adequately sensitive or specific for diagnosis as up to 50% being asymptomatic. Parasitologic diagnosis was usually a must. Diagnosis of trichomonasis was traditionally based on demonstration of the parasite in the normal saline wet mounts of vaginal swaps. In this study, 15/167 married women had T. vaginalis. Wet mount preparation showed 38.5% sensitivity, 98.7% specificity, 71.4% positive predictive value and 95% negative predictive value. InPouch TV culture showed 86.7% sensitivity, 100% specificity, 100% positive predictive value and 98.7% negative predictive value. The results were discussed.
