Tests and diagnosis

By Mayo Clinic Staff

In some cases, your doctor may be able to diagnose athlete's foot simply by looking at it. To help confirm the diagnosis and rule out other conditions, your doctor might:

  • Take skin scrapings or samples from the infected area and view them under a microscope
  • View your feet under black light from a Wood's light
  • Send a small sample of your skin to a lab to be tested
