OMG, forget the IgM! It has many false positives and the CDC says never to do it.
It is possible that the 2nd test is reflecting new infection,yes, but it could also be a false positive.
We can set up a western blot together but it is way too early for that. I wouldn’t even get started on that for several weeks. You could do another IgG test at 6 weeks and see if the index value is going up or staying around the same.
Do you have symptoms of herpes? Is that why you tested?
