A healthy woman’s leukorrhea should be white, or clear and odorless. If a woman finds an abnormality, she should go to the hospital for a routine white belt test as soon as possible. In general, a routine leuko test usually includes tests for pH, vaginal cleanliness, mold and trichomonas, and clue cells. For women who have had sex, the vagina should be dilated with a vaginal dilator to check the condition of the vagina, cervix and leukorrhea, and then a cotton swab should be dipped into the leukorrhea and sent to the laboratory for examination. You should avoid bathing, vaginal douching and sexual intercourse for 24 hours before the test, and avoid vaginal medication for 72 hours. It is important to pay attention to personal hygiene, showering and changing clothes regularly. Please note that the vulva should be washed with warm water daily. You need to go to a regular hospital to perform the routine white belt examination. If you have not had sex, you must inform the doctor before that you cannot do the vaginal examination, don’t be too nervous during the examination and just be prepared.
