How is jock itch diagnosed?

Jock itch can be diagnosed by the following tests: 1) Potassium hydroxide exam - a scraping of your skin from the affected area is added to potassium hydroxide (KOH) and examined under a microscope. KOH destroys non-fungal cells, making it easier to see if any fungal cells are present. 2) Fungal culture - if fungus is present on the skin, it can be cultured using a special gel plate that selectively grows it. 3) A skin biopsy, in which a sample of skin is removed and tested for abnormalities such as an infection. It is performed only when other skin infections need to be ruled out.
