In brief: Genital herpes HSV1

Up to 30% of people with HSV1 don't get positive blood tests, after 6 months or forever. If the swab test was positve, you have HSV1, no need for further blood tests.
Herpes zoster does not interfere with HSV blood test or PCR. Acne pad makes no difference. The good news is that most people with genital herpes from HSV1 have few or no recurrences and don't transmit to partners. No big deal!
