Definition

This is a test for vaginitis (an infection of the vagina that does not include the urinary tract). The symptoms may include itching, pain, vaginal odor, and a vaginal discharge.

Alternative Names

Wet prep

How the test is performed

You will be asked to lie on your back with your feet in the stirrups. A pelvic examination will be done, and a speculum (an instrument used to keep the vagina open in order to examine the interior) will be inserted into your vagina and opened slightly.

A sterile, moist cotton swab is inserted, and a sample of the discharge is taken. The swab, and then the speculum, are removed . Slides from the discharge are prepared, then viewed under a microscope.

How to prepare for the test

Do not douche for 24-hours before the test.

For infants and children:

The preparation you can provide for this test depends on your child's age, previous experiences, and level of trust. For general information regarding how you can prepare your child, see the following:

How the test will feel

There may be a slight discomfort with the pelvic examination.

Why the test is performed

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

Normal Values

A normal value occurs when there is no indication of an infection.

What abnormal results mean

Abnormal results indicate infection, and the most common infections are caused by one of these sources, or a combination:

  • A vaginal yeast infection (caused by Candida albicans) -- resulting in a white, cheesy discharge; severe itching; painful intercourse; and a rash or vaginal inflammation.
  • Trichomoniasis, an infection caused by a protozoan parasite -- produces a yellowish, frothy, foul-smelling discharge. Sores can develop on the cervix. There may be pain on urination or intercourse.
  • A bacterial infection (gardnerella vaginalis or haemophilus vaginalis) -- producing bacterial vaginosis. The symptoms are a heavy, white, fishy-smelling discharge. There may be a rash or painful intercourse, or odor after intercourse.

Different treatments are necessary for each type of infection. Of the above infections, only Trichimoniasis is a sexually transmitted infection.

Additional conditions under which the test may be performed:

What the risks are

There are no risks.

Special considerations

If the infection is caused by trichomoniasis or a bacterium, the sexual partner should be treated also. This prevents the partners from being re-infected after the treatment.

It is possible to have an inflammation of the vagina from chemical irritation (such as from bubble bath or vaginal spray), mechanical abrasion (a scraping away at the surface), or a lack of estrogen.
