Thank you for your response,
This is conclusive that you have an HSV1 infection.
There is no way you were infected a few days before this blood test. You have most probably had this infection since your youth. Some people have a reading like this, many labs cut off at 5, 7 or similar.
If you're worried about HSV2, you need to test from 16 weeks after exposure.
Forgot to mention. I've never, that I can remember, have had an outbreak.
