Leukorrhea examination can be done by using a cotton swab to take secretions from the vaginal opening for unmarried people, while married people need to be assisted by a speculum to take vaginal secretions for smear examination. Leukorrhea examination is a commonly used gynecological examination. Leukorrhea examination can be used for the diagnosis of inflammation and tumor in the female reproductive system, as well as for the determination of estrogen level. For unmarried women who are not sexually active, it is usually sufficient to use a cotton swab to take secretions from the vaginal opening; for married women who are sexually active, it is necessary to open the vagina with a speculum, take secretions from the deep part of the vagina, or the posterior fornix, or the opening of the cervical canal, etc., with a cotton swab, and then prepare thin smears or place the specimen in a test tube containing saline and send it to the hospital for examination. If there is any discomfort, it is recommended to consult a medical professional for standardized diagnosis and treatment.
