Wet Mount/KOH Procedure

Definition/Purpose

A sample of vaginal discharge is mixed with a salt solution on a microscope slide. The slide is checked for bacteria, white blood cells, and unusual cells called clue cells. If clue cells are present, it means bacterial vaginitis is present. KOH (potassium hydroxide) medium is used to enhance the recovery of fungi. Body fluid pH is calculated with the use of pH paper.

The direct examination of a clinical specimen is the most rapid, cost-effective diagnostic aid in the laboratory. Microscopic examination of a sample is used to identify the motility and morphology of microorganisms, fungal elements, protozoan trophozoites and helminthes eggs and larvae. The visual examination assists the laboratory and the clinician in quickly identifying the causative agent of infection so treatment may begin. Proper sample collection is important in diagnosing infection. Samples may be treated with potassium hydroxide (KOH) to enhance the recovery of fungi or stained with iodine to enhance the recovery of trophozoite nuclei and vacuoles. Wet mount samples may be obtained from various clinical sites and sources.

Equipment:

Exam gloves

Cotton tipped swabs (2) and Kova Tubes (2)

Specimen (obtained during speculum examination for vaginal secretions or by clinician for other sources)

Normal Saline, KOH, Sedi Stain (KOH Protect from light)

2 clean microscope slides with cover slips

Microscope

pH paper

Scalpel, tongue blade, skin curette, or other blunt object (Skin Scrapings)

Red Hazardous Waste Container

Procedure:

Vaginal Wet Mount

1. Put on gloves.

2. Obtain the specimen with cotton tipped applicator. See Pelvic Exam Procedure.

Specimens should be examined within two hours of collection. The sample should remain at room temperature. Proper specimen collection and handling of vaginal samples is crucial for accurate results. The vaginal vault and walls should be swabbed using one or two swabs. If any fluid has pooled in other areas, these areas should be swabbed as well. Use of vaginal lubricants, douches, tampons, contraceptive jelly, and medications may interfere with the examination. Patients should avoid using these items before sample collection. In some cases, the gram stain may be used to aid in the diagnosis of these patients.

3. Do one/or more of the following:

a. Put one drop of normal saline in Kova tube; insert cotton-tipped applicator with specimen. Vigorously mix the swab (s) in and out of the saline making sure to collect all the material adhering to the side of the tube. Remove the swab from the saline and depress onto a clean, dry microscope slide expressing a small amount of fluid.

b. Insert cotton-tipped applicator with specimen into dry Kova tube. Put one drop of potassium hydroxide (KOH) on the right third of the slide. Mix the sample of vaginal discharge on the wooden end of the cotton-tipped applicator with the drop of KOH on the slide. Use both a rolling and a stirring motion to mix the vaginal discharge with the drop of solution.

c. Place cotton-tipped applicator with specimen in Kova tube. Use two clean microscope slides and put one drop of normal saline on the middle of one slide and one drop of potassium hydroxide on the middle of the second slide. Roll the plain wooden end of a cotton-tipped applicator in the specimen of vaginal discharge. Mix the sample of vaginal discharge on the wooden end of the cotton-tipped applicator with drop of normal saline on the slide. Repeat and mix the sample with the drop of potassium hydroxide if both solutions are being used. Use a rolling and a stirring motion to mix the vaginal discharge with the drop of solution.

4. The pH and the amine (whiff) test often are performed before the microscopic examination. The clinician test the pH at the time of sample collection a pH greater than 4.5 may indicate bacterial vaginitis (BV) or trichomoniasis. The amine test is performed prior to cover slipping the saline preparation. The fishy or amine odor is characteristic in the presence of Trichomonas vaginalis and Gardnerella vaginalis.

5. Cover the mixture of specimen sample and solution with a cover glass (coverslip) by sliding the coverslip onto and over the specimen. This is accomplished by putting the edge of one side on the coverslip into the mixed specimen/solution and drawing it to the longitudinal edge of the slide. When the specimen/solution is under the entire edge of the side of the coverslip, slide the coverslip over the rest of the mixed specimen/solution on the slide.

6. The wet smear slide of vaginal secretions is now ready for microscopic evaluation.

7. Examine secretions. The saline slide should be examined first to allow the KOH to properly digest other cellular elements in the sample such as epithelial and blood cells.

8. 8. Begin the microscopic review of the slide by examining the saline preparation. The examination should begin using the 10x objective noting cellular distribution and obvious cellular and fungal elements. The 40x objective is used to identify the cells, motile Trichomonas, yeasts, and fungal hyphae. The KOH slide should be examined with the 10x objective for any yeast and hyphae.

9. Discard slides in Red Hazardous Waste Containers and maintain universal precautions in glove disposal and hand washing.

Skin Scrapings

Skin scraping examinations are used to identify fungal infections of the skin, mouth and nails. Fungus lives in the stratum corneum layer of the skin. KOH is used to digest this layer of skin so that the fungal growth with its visible hyphae and spores is exposed. Skin scraping examinations are indicted in areas of broken hair or baldness, presence of scaly lesions on the skin, crumbling or scaly nails or nail beds, and white plaque in the mouth.

The proper collection of a skin scraping sample is crucial to the recovery of the fungus. In obtaining and preparing the sample:

10. Clean the infected area with 70% alcohol. Scrape the infected area using a scalpel, skin curette, tongue blade, or other blunt object. Infected nails may require a portion of the infected nail to be clipped.

11. Place the sample on a microscopic slide and coverslip.

12. Apply gently heat (if practitioner desires) to enhance the digestive capabilities of the KOH. If 40% dimethyl sulfoxide (DMSO-KOH) is used, heating the sample is unnecessary.

13. Let the slide sit for 10 minutes to allow for KOH digestion.

14. Examine the slide using teh10x objective. All suspicious areas should be examined using the 40x objective.

15. Keep the light intensity of the microscope low. I the light intensity is too high, the fungal elements may not be seen.

16. Discard slides in Red Hazardous Waste Containers and maintain universal precautions in glove disposal and hand washing.

Documentation

Order for vaginal wet mount (vaginal wet prep) and results are documented in the patient electronic health record. Documentation includes the patient name, date, time, specimen source, and findings. The comment section of the result includes the initials of the examining clinician.

Preparation and Storage of solutions (KOH and Sedi Stain) and pH paper is per manufacturers recommendation. See package inserts. MSDS on file.

No calibration is required.

No alert values.

Specimens may be referred to a reference lab for testing as ordered.

Quality Control

Every 6 months clinicians will compare results from two patient specimens and document findings for peer review. Discrepancies will be discussed, comments will be documented. Laboratory Directory will review and sign Peer Review for Vaginal Smear Wet Mounts. (See attached copy.)
