Can a test tell the difference between HSV-1 and 2?
PCR finds the genetic material ( DNA ) of the HSV virus. This test can tell the difference between HSV-1 and HSV-2. Using the PCR test on skin sores isn’t common. PCR is used mainly for testing spinal fluid in rare cases when herpes may have caused an infection in or around the brain.
Is type 1 herpes the same as Type 2?
