Tests and diagnosis

By Mayo Clinic Staff

In many cases, your doctor can diagnose jock itch simply by looking at the rash. If the diagnosis isn't clear-cut, your doctor may take skin scrapings or samples from the infected area and view them under a microscope. To rule out other conditions, your doctor might send a sample of the rash to a lab. This test is known as a culture.
