A skin lesion KOH exam is a diagnostic test used to determine whether an infection of the skin is caused by a fungus. Athlete’s foot is one of the most common fungal infections of the feet, and the KOH exam can be used to test for it. When a doctor performs this test, they will scrape a small piece of skin off of the affected area and then mix this sample with potassium hydroxide (KOH). The KOH destroys healthy skin cells in the sample, leaving behind only the cells of the fungus, if one is present. The KOH exam is simple, straightforward, and relatively painless. If positive results are obtained, treatment of the fungal infection can begin. If you suspect that you may have athlete’s foot, it is recommended that you visit a podiatrist for diagnosis and treatment.

Athlete’s foot is an inconvenient condition that can be easily reduced with the proper treatment. If you have any concerns about your feet and ankles, contact Dr. Steven Sheridan from Ankle & Foot Specialty Clinics.  Our doctor will treat your foot and ankle needs.
