Purpose of the Test

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

When this test is required

A healthcare provider may request a hair test for fungus stain using KOH preparation if a person has symptoms of a fungal infection of the scalp, hair, or beard, such as itching, scaling, redness, or hair loss. The test may also be ordered if other diagnostic tests, such as a fungal culture or biopsy, are inconclusive or if there is a suspicion of fungal infection.

What the Test Detects

A hair test for fungus stain using KOH preparation is used to detect the presence of fungal organisms in a hair sample. The test is used to diagnose fungal infections of the scalp, hair, and beard and to identify the type of fungus causing the infection.

Preparation for the Test

Test preparation for a hair test for fungus stain using KOH preparation is relatively simple. The healthcare provider will clean the area around the hair or hair shaft and then use a pair of forceps or tweezers to collect the hair or hair shaft. The hair or hair shaft 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 hair test for fungus stain using KOH preparation is a hair or hair shaft collected from the scalp, hair, or beard using a pair of forceps or tweezers. The healthcare provider will determine the appropriate method for collecting the sample based on the location and type of infection suspected.

Additional Notes

The hair test for fungus stain using KOH preparation is a simple and non-invasive test that can be performed in a healthcare provider’s office. The test is generally well-tolerated, and there is no significant risk associated with the procedure. However, it is important to follow the healthcare provider’s instructions regarding the collection of the hair sample to ensure that a valid result is obtained. If a fungal infection is identified, the healthcare provider may prescribe antifungal medications to treat the infection.
