Skin Scrapping for Fungus Stain/Fungal Smear (KOH)

Specimen Required

SKIN SCRAPPING

Fasting Required

Purpose of the Test

A skin scraping test for fungal stain using KOH preparation is used to diagnose fungal infections of the skin, hair, and nails. The test is used to detect the presence of fungal organisms in a sample and is useful in identifying the type of fungus causing the infection.

When this test is required

A healthcare provider may request a skin scraping test for fungal stain using KOH preparation if a person has symptoms of a fungal infection, such as itching, redness, scaling, or blistering of the skin, or if they have a history of exposure to fungi. The test may also be ordered if other diagnostic tests, such as a skin culture, are inconclusive or if there is a suspicion of fungal infection.

What the Test Detects

A skin scraping test for fungal stain using KOH preparation is used to diagnose fungal infections of the skin, hair, and nails. The test involves examining a sample of skin, hair, or nail under a microscope for the presence of fungal organisms. The potassium hydroxide (KOH) solution is used to dissolve any non-fungal material, making it easier to see the fungal organisms under the microscope.

Preparation for the Test

Test preparation for a skin scraping test for fungal stain using KOH preparation is relatively simple. The healthcare provider will clean the area to be sampled and then use a sterile scalpel or scraper to collect the sample. The sample is then placed on a slide and treated with potassium hydroxide (KOH) solution to dissolve any non-fungal material and make it easier to see the fungal organisms under a microscope. No special preparation is required for the person undergoing the test.

Sample Requirements

The sample required for a skin scraping test for fungal stain using KOH preparation is a small sample of skin, hair, or nail collected using a sterile scalpel or a skin scraper. The healthcare provider will determine the appropriate method for collecting the sample based on the location and type of infection suspected.

Additional Notes

In addition to the skin scraping test for fungal stain using KOH preparation, the healthcare provider may order additional tests, such as a fungal culture or a biopsy, to confirm the diagnosis of a fungal infection. Treatment for fungal infections may involve the use of antifungal medications, topical creams, or oral medications, depending on the severity and location of the infection. It is important to follow the healthcare provider’s instructions for treatment and infection control to prevent further complications.
