In most cases, your doctor can diagnose a plantar wart with one or more of these techniques:

  • Examining the lesion
  • Paring the lesion with a scalpel and checking for signs of dark, pinpoint dots — tiny clotted blood vessels
  • Removing a small section of the lesion (shave biopsy) and sending it to a laboratory for analysis
