Tests and diagnosis

By Mayo Clinic Staff

our doctor usually can diagnose genital herpes based on a physical exam and the results of certain laboratory tests:

  • DNA test. A sample of your blood, sore tissue or spinal fluid can be tested to establish the presence of HSV and determine which type of HSV you have.
  • Blood test. This test analyzes a sample of your blood for the presence of HSV antibodies to detect a past herpes infection.
  • Viral culture. This test involves taking a tissue sample or scraping of the sores for examination in the laboratory.
