First, thank you, I try.
Second, I would be quite surprised if an HSV 2 ELISA at 8.39 came back negative on western blot. Do you know if you had both tests done at the same lab? If different brands are used, there can be some variation in the index values, though this is a very big difference.
If the western blot is negative, I would believe it, yes.
I have not personally seen a false positive this high, but then, I don’t western blot people who have a value this high. I have seen false positives above 4.5, just in the past year.
