label_lc: positive skin fungus test
description: "A test for fungus, e.g., fungal hyphae, in a skin specimen (usually a skin scraping), demonstrates the presence of fungi. Most commonly, a skin scraping is obtained using a small scalpel blade, the specimen is placed on a clean glass slide, a drop of potassium hydroxide (KOH) is added, and the specimen is examined microscopically for fungal structures such as hyphae or yeast."
