What happens during a polymerase chain reaction (PCR) test for herpes?

ANSWER

For this test for genital herpes, your doctor swabs or scrapes a sample from one of your sores. A lab gets the sample and looks for genes from the herpes virus. PCR test results usually come back to you within 24 hours.

You’re more likely to get this test if you have symptoms but it’s been longer than 48 hours since they showed up.
