Many people get a positive IgG the first time around, then Quest does the inhibition assay, but it can’t be done because they do another IgG first and it is negative. I would bet a lot of money that you are actually negative for HSV 2. There is good agreement between people who get the negative inhibition assay (it can’t be done because the second IgG is negative) and people who subsequently get a negative western blot
