Vaginal Wet Mount

Wet Mount, Vaginal

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.

Vaginal discharge

Normal:	No abnormal vaginal discharge is present. A small amount of discharge is normal.
Abnormal:	A white, lumpy discharge that looks like cottage cheese may mean a vaginal yeast infection is present. A yellow-green, foamy discharge that has a bad odor may mean trichomoniasis is present. A thin, gray-white vaginal discharge with a strong fishy odor may mean bacterial vaginosis is present.

 

Wet mount

Normal:	No yeast, bacteria, trichomoniasis, or clue cells are found on the slide. White blood cells are not present or very low in number.
Abnormal:	High numbers of white blood cells often mean a vaginal infection. Yeast cells found on the wet mount mean a vaginal yeast infection is present. Trichomonads on the wet mount mean trichomoniasis is present. Clue cells means bacterial vaginosis is present. If many Gardnerella vaginalis bacteria are present, this also may mean bacterial vaginosis is present.

 

KOH slide

Abnormal:	Yeast cells means a yeast infection is present.

 

Vaginal pH
