I often see people with this kind of situation be negative by western blot for HSV 2. As I said aboe, I would guess there is about a 40% chance that your HSV 2 is a false positive. That means that out of 100 times when I see someone who has an HSV 1 positive that is high and an HSV 2 that is in the range, 60 people confirm their HSV 2 index value as a true positive and 40 people turn out to be negative for HSV 2 by western bot.
It doesn’t matter at all that you only tested for HSV 2. There likely is some cross reactivity between the two antibody tests.
