She also complains of itching and soreness. The medical history is unremarkable. She is not diabetic. She has been sexually active with a single partner for the last 3 years. A vaginal swab is sent to the lab for microscopic evaluation, the results of which are shown in the exhibit, and the culture yields heavy growth of protozoa. A pregnancy test was negative.
