Vaginitis test - wet mount

Wet prep - vaginitis; Vaginosis - wet mount; Trichomoniasis - wet mount; Vaginal candida - wet mount

The vaginitis wet mount test is a test to detect an infection of the vagina.

How the Test is Performed

This test is done in your health care provider's office.

  • You lie on your back on the exam table. Your feet are supported by footrests.
  • The provider gently inserts an instrument (speculum) into the vagina to hold it open and view inside.
  • A sterile, moist cotton swab is gently inserted into the vagina to take a sample of discharge.
  • The swab and speculum are removed.

The discharge is sent to a lab. There, it is placed onto a slide. It is then viewed under a microscope and checked for signs of infection.

How to Prepare for the Test

Follow any instructions from your provider on preparing for the test. This may include:

  • In the 2 days before the test, DO NOT use creams or other medicines in the vagina.
  • DO NOT douche. (You should never douche. Douching can cause infection of the vagina or uterus.)

How the Test will Feel

There may be slight discomfort when the speculum is inserted into the vagina.

Why the Test is Performed

The test looks for the cause of vaginal irritation and discharge.

Normal Results

A normal test result means there are no signs of an infection.

Normal value ranges may vary slightly among different laboratories. Some labs use different measurements or test different samples. Talk to your provider about the meaning of your specific test results.

What Abnormal Results Mean

Abnormal results mean there is an infection. The most common infections are due to one or a combination of the following:

  • Bacterial vaginosis. Bacteria that normally live in the vagina overgrow, causing a heavy, white, fishy-smelling discharge and possibly a rash, painful intercourse, or odor after intercourse.
  • Trichomoniasis, a sexually transmitted disease.
  • Vaginal yeast infection.

Risks

There are no risks with this test.

  • Uterus

    Uterus - illustration

    The uterus is a hollow muscular organ located in the female pelvis between the bladder and rectum. The ovaries produce the eggs that travel through the fallopian tubes. Once the egg has left the ovary it can be fertilized and implant itself in the lining of the uterus. The main function of the uterus is to nourish the developing fetus prior to birth.

    During a Pap smear, cells from the outside and the canal of the cervix are retrieved by gently scraping the outside of the cervix. The Pap smear is performed to detect cancerous or precancerous conditions of the cervix.
