What are tests to diagnose or screen for genital herpes?

ANSWER

Tests used to diagnose or screen for genital herpes include:

  • PCR blood test: The PCR blood test can tell if you have genital herpes even if you don't have symptoms. The PCR test looks for pieces of the virus's DNA. This is the most common test used to diagnose genital herpes and is very accurate.
  • Cell culture: During the exam, your health care provider can take a sample of cells from a sore and look for the herpes simplex virus (HSV) under a microscope.
