I dont know much about the testing side to be honest. It lies latent in neurons. Not sure whether its a blood test or a culture of the sore to determine virus type.
Don't get too down about it. May be something, may be nothing. There are vast amounts of people in the US and around the world who live with it daily and the new drug treatments are huge leaps forward from not long ago. You'll be fine. Dont worry.
