While it is possible that this is a false positive, I would say that given the higher level index values, it is likely to confirm as positive if you did the western blot, but if you aren’t sure, that is the test that I would recommend. We have seen false positives as high as 17 on the HSV 2 IgG test so if you have any question, do the blot.
