Doc. told me test came back 20% out of 80% positive for herpes 1 . but i haven't ever had a cold sore , how am i positive ?

More info needed: These numbers don't make sense. Clarify with your doctor; or perhaps ask for a copy of the test report and return with a new question reporting exactly what it says. But if positive, no big deal. Almost half of all adults have positive HSV1 blood tests, and most have never had known oral herpes. It's still usually an oral infection acquired in childhood. It's normal.
