Diagnosis

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

• Examining the wart
• Scraping off the top layer of the wart to check for signs of dark, pinpoint dots — clotted blood vessels — which are common with warts
• Removing a small section of the wart (shave biopsy) and sending it to a laboratory for analysis to rule out other types of skin growths
