KOH prep is performed for the rapid evaluation of Candida. Spread a sample of the cervical or vaginal pool specimen onto a microscope slide, add one drop of potassium hydroxide (KOH), and apply a cover slip. Note any odor. Examine under the microscope. The presence of yeast and pseudohyphae forms (chains of budding yeast) indicates an overgrowth of Candida. Normal saline is used to count WBCs, indicative of an inflammatory response (bacterial, protozoan, Chlamydia trachomatis). Sterile water is not used; a 5% acetic acid (vinegar) is utilized to identify to presence of human papillomavirus.
