1. Evaluation of the vagina begins with close inspection of the external genitalia for excoriations, ulcerations, blisters, papillary structures, erythema, edema, mucosal thinning, or mucosal pallor.
2. The color, texture, and odor of vaginal or cervical discharge should be noted.
D. Vaginal fluid pH. The pH level can be determined by placing pH paper on the lateral vaginal wall or immersing the pH paper in the vaginal discharge. A pH level greater than 4.5 often indicates the presence of bacterial vaginosis. It may also indicate the presence of Trichomonas vaginalis.
