Taking the leukorrhea for a routine leukorrhea test is a very simple operation and does not necessarily require the use of a dilator. The choice is based on whether the patient is married or unmarried, and whether she is a virgin. The routine white belt test is mostly used for vaginal inflammation and can determine if it is trichomoniasis, mycotic vaginitis, mycoplasma infection, chlamydia, bacterial vaginitis, etc. Before the test, we must ask the patient if she has a history of sexual life. Women who do not have a sexual life should not use a dildo, but can use a cotton swab to dip the vaginal opening in the discharge to do the test. Married women or women who are already sexually active can use a dilator during the examination because not only can they get the leukorrhea, but they can also observe the vaginal wall and the cervix. Then, 48-72 hours before the examination of the leukorrhea, you must not wash the vulva or douche the vagina, nor use medication or have sexual intercourse, nor apply lubricant to the dilator, which can affect the examination results.
