Tests and diagnosis

By Mayo Clinic Staff

Your doctor can usually diagnose a wart just by looking at it. Sometimes, your doctor may scrape off the top layer of the wart to look for the clotted blood vessels that are common with warts. If the diagnosis is still in doubt, your doctor may take a small sample to be analyzed in order to rule out other types of skin growths.
