About Koh Examination

A KOH (Potassium Hydroxide) examination is a quick, in-office diagnostic test performed by a dermatologist to identify fungal infections of the skin, hair, or nails. During the procedure, a small sample of skin scales, nail clippings, or hair is collected and treated with a KOH solution on a microscope slide. This chemical dissolves keratin, the protein in skin cells, leaving behind any fungal elements like hyphae (branching filaments) or spores, which become clearly visible under a microscope. This simple, non-invasive test provides rapid results, often within minutes, allowing for immediate and accurate diagnosis of conditions like ringworm (tinea), athlete's foot, or nail fungus, enabling the dermatologist to prescribe the most effective antifungal treatment promptly.

PATIENT REVIEW

Reyansh Verma, a 28-year-old software engineer,...

Reyansh Verma, a 28-year-old software engineer, had been dealing with a persistent, itchy rash on his scalp and beard for over two months. Initially, he thought it was just dandruff or a reaction to a new shampoo, but the itching became intense, and he noticed flaky, red patches. As someone who prided himself on his appearance, he felt self-conscious and avoided social gatherings. His dermatologist, Dr. Sharma, recommended a KOH examination to check for a fungal infection. During the procedure, Reyansh felt a slight scraping sensation as the doctor collected a small sample from his scalp. The quick, in-office test confirmed tinea capitis and barbae. With a diagnosis in hand, Reyansh started a course of oral antifungal medication and medicated shampoo. Within two weeks, the itching subsided significantly, and the patches began to clear. Emotionally, he moved from frustration and embarrassment to immense relief, feeling back in control of his health and confident again.
