1. Herpes is rarely serious. Herpes is an extremely common and widely feared infection, but in most cases it's not very serious. "Most genital herpes infections are asymptomatic and the fear of herpes is more psychological than it is physical," says H. Hunter Handsfield, MD, a clinical professor of medicine at the University of Washington in Seattle and a nationally recognized STD expert. "It's basically just a skin disease."
2. Some tests are unreliable. If you do get a herpes blood test, Dr. Handsfield says to make sure it’s a “type-specific” test, which he finds much more reliable than other types.
A note about suppressive therapy
If you test positive, taking an anti-viral drug may help you avoid outbreaks and reduce viral shedding, which means you’re less likely to infect sex partners. The drugs are fairly benign, Dr. Marrazzo says, but she questions whether it's really worth treating a relatively harmless, incurable infection if it was causing you no symptoms. "The main side effect is you're taking a drug every day and you're paying for it. Do you really want to go on a drug every day?"
