Vaginal Wet Mount
How To Prepare
Do not douche, use tampons, or use vaginal medicines for 24 hours before the test.
A vaginal wet mount is not done during your menstrual period. Menstrual blood on the slide can change the results.
If you are or might be pregnant, tell your doctor before the vaginal wet mount is done.
How It Is Done
You will take off your clothes below the waist and drape a gown around your waist. You will then lie on your back on an examination table with your feet raised and supported by stirrups. This allows your doctor to look at the genital area.
Your doctor will put a smooth, curved speculum into your vagina. The speculum gently spreads apart the vaginal walls, allowing your doctor to see the inside of the vagina and the cervix.
Samples of fluid inside the vagina are taken with a swab or spatula. The sample is put on a slide for testing.
How It Feels
You may feel some discomfort when the speculum is inserted, especially if your vagina is irritated and tender. There may be a small amount of bleeding after this test.
Risks
There are no problems from collecting a sample of vaginal secretions.
Results
A vaginal wet mount (sometimes called a vaginal smear) is a test to find the cause of vaginitis, or inflammation of the vagina and the area around the vagina (vulva). Your doctor may talk to you about the results after the test. If the sample needs to be looked at by a lab, the results may be ready in 1 to 2 days.
