It is not necessary to fast for the routine leucorrhea test, because the results of the routine leucorrhea test are not related to not eating. It is recommended to pay attention to the following items: 1) Do not have intercourse, as intercourse can affect the results of the routine leucorrhea test. 2) Do not use vaginal pills, as vaginal pills can mask symptoms and reduce the likelihood of positive results. 3) Do not use vaginal douching. The results of the routine leucorrhea test will show the cleanliness of the vagina and the presence of pathogenic bacteria in the vagina, and the results will determine whether treatment should be given. In addition, women should strengthen the local care of the vulva in their daily life, especially during ovulation, when the leucorrhea will increase before menstruation, and wash the vulva 1-2 times a day to avoid pathogenic bacterial infections.
