A positive test for hydrogen peroxide and a weak positive test for leukocyte esterase during a routine leukorrhea test suggests the presence of vaginal inflammation due to an imbalance in the vaginal flora environment. When the pH value changes, it can also cause hydrogen peroxide positive and leukocyte esterase weak positive. If there is no discomfort, it can be treated with a gynecological cleansing disinfectant and antiseptic lotion, and can usually be improved with 7 days of medication. If accompanied by vulvar itching, including odor, this is the time can be carried out vaginal plugs, metronidazole suppositories or bisacodyl cream, one capsule every night, with the drug 7 days can be resolved to improve. At the same time, when there is hydrogen peroxide positive, as far as possible, should also be carried out TCT and HPV cancer screening to rule out. Because persistent hydrogen peroxide positivity can predispose to complications of HPV infection, cytology is also needed if possible.
