Shingles is diagnosed by its pain and its specific rash. To confirm that you have shingles, your doctor may scrape some skin from a blister or collect some of its fluid for testing. The tests can detect the presence of the varicella-zoster virus.
These tests include:
- Microscopic examination
- Viral culture
- Polymerase chain reaction techniques
It may take three to several weeks to obtain the results of some of these tests.
