    Signs and tests

    Your health care provider can usually diagnose jock itch based on how your skin looks.

    Tests are usually not necessary. If tests are needed to confirm the diagnosis, either a culture or a skin lesion biopsy (for example, a scraping of the skin) may be done. A KOH (potassium hydroxide) test may be done in the office for quick diagnosis.
