Purpose of the Test

The Hairs for Fungal Culture and Fungal Stain (KOH) test is used to diagnose fungal infections of the hair and scalp. The test helps identify the specific type of fungus causing the infection and determine the appropriate treatment.

When this test is required

Your healthcare provider may request this test if you have symptoms of a fungal infection of the hair and scalp, such as hair loss, scaling, itching, or other signs of infection. The test is also ordered if you have a suspected fungal infection that is not responding to treatment.

What the Test Detects

The Hairs for Fungal Culture and Fungal Stain (KOH) test is a medical test that helps diagnose fungal infections of the hair and scalp. The test involves two parts: a fungal culture and a fungal stain. In the fungal culture, the collected hair sample is placed in a special medium that promotes the growth of fungi. If fungi grow, they can be identified using various laboratory techniques. In the fungal stain, the sample is treated with potassium hydroxide (KOH), which helps dissolve any non-fungal material, leaving behind any fungi present. The fungi are then stained and examined under a microscope.

Preparation for the Test

There is no specific test preparation required for the Hairs for Fungal Culture and Fungal Stain (KOH) test. However, your healthcare provider may provide specific instructions on how to prepare for the test, such as washing your hair or avoiding certain hair care products before the test. It is important to follow your healthcare provider’s instructions carefully to ensure an accurate test result.

Sample Requirements

To perform the Hairs for Fungal Culture and Fungal Stain (KOH) test, a sample of hair from the affected area is collected. The hair should be gently pulled out by the roots with forceps or scissors. In some cases, a skin scraping or biopsy may also be taken. It is important to ensure that the hair is not contaminated with bacteria or other microorganisms during collection.

Additional Notes

The Hairs for Fungal Culture and Fungal Stain (KOH) test is a relatively safe and simple test. However, like all medical tests, it may have some risks or limitations. For example, the test may produce false-positive or false-negative results. Additionally, some fungal infections may be difficult to diagnose, and the test may need to be repeated or supplemented with other tests. Your healthcare provider will discuss the risks and benefits of the test with you and explain the results. It is important to follow your healthcare provider’s instructions for collecting the sample and to report any unusual symptoms or complications after the test.
