To diagnose yeast infection, your health care provider may review your history of vaginal infections as well as conduct a pelvic examination to look for inflammation of the skin of the vaginal area and on the cervix, and may look for dry, white plaques on the vaginal wall.
During the pelvic exam, your health care provider may conduct a vaginitis test called a wet mount. Taking a wet mount consists of inserting a sterile, moist cotton swab into the vagina to take a sample of the discharge. The sample will be put under a microscope to look for an overgrowth of Candida albicans, which would confirm a yeast infection. Once the presence of a yeast infection is confirmed, your health care provider may recommend over-the-counter or prescription treatment to clear up the infection.
