After choosing vaginal medication for vaginal or cervical inflammatory disease, patients need to stop using the medication for three days to check their leukorrhea. Patients should not use vaginal medications or douche their vagina before the leuko check to ensure the accuracy of the test results. Patients should also not have intercourse after stopping the medication. If the patient’s inflammation is not completely treated, the patient can easily cross-infect the male by intercourse, or the female vaginitis has been cured, but the male can cross-infect the female if he carries the bacteria. If the patient has menstruation or vaginal bleeding after three days of medication, it is also not advisable to perform a leucorrhoea test because the blood flushing the vagina will easily flush out the leucorrhoea and pathogenic bacteria. The results of the test are also affected by the fact that the amount of leukorrhea obtained is very small or not enough, and that the secretions obtained are mixed with a large amount of blood.
