that I was familiar with and as far as I know, doesn't have Herpes. I didn't wear a condon and it was a one time encounter. After I told my wife she went and got tested about a week ago and received the results back yesterday. She said that the HSV 2 results were positive. The test used was a blod test. My question is two part. 1.) Is there any hope that the blood test yeilded a false positive and 2.) How soon would HSV 2 show up in a test like this?
