We recommend that people wait 12 weeks for a final result – 50% of people who are going to be positive are positive by 3 weeks out and at 6 weeks, 70%. So it might be early for you. But if you’ve had no symptoms at all, you may well not be infected at all. The other issue here is that the IgG test for HSV 1 misses 30% of infections – not terribly sensitive. On the other hand, with no symptoms, a single encounter and no known herpes in your partner, I think the chances of you being infected is quite low.
