Diagnosis of Shingles

The more you know about your health, the better prepared you are to make informed healthcare decisions. Our health library gives you the information you need to take charge of your health.

Generally, shingles is easily diagnosed by its characteristic discomfort/pain and its distinctive rash. To confirm that you have shingles, your doctor may scrape some skin from a blister or collect some of its fluid. These samples can then be sent to a laboratory for testing. The tests can detect the presence of the varicella-zoster virus.

These tests include:

  • Microscopic examination
  • Viral culture
  • Immunofluorescence
  • Polymerase chain reaction techniques

It may take as long as three weeks or several weeks to obtain the results of some of these tests.
