Were both tests done at the same lab? That is a huge difference – could you recently have become infected with HSV 1?
I think it is very likely that your HSV 2 is a false positive. But then the test for HSV 1 is so poor, I’m not completely surprised.
The western will tell you if you are infected with HSV 1, HSV 2, neither or both, correct. If you have antibody to these viruses by western blot, then you are infected and potentially infectious to others, correct.
