I don’t think you can gather much from this. There is, as you already know, variation from test to test and this is certainly within the range of normal variation.
It is my opinion that probably most false positives are due to a cellular protein of a person’s own body that trips the test artificially. Chicken pox would not trip the test artificially. I’m working with a scientist who is developing a new test for herpes to try to sort out some of these low positives and that is what he believes, and I think that is a common response among the herpes testing experts, also.
When are you taking the western blot antibody test? Let me know the results – I will be very interested.
