Yes, I believe that the first test was a false positive. I don’t love the inhibition assay as a confirmatory test because I have seen it confirm tests that are completely negative by western blot considered the gold standard in herpes testing. But this time the inhibition assay was negative, which makes me happy. I don’t think that there is anything else that you need to do. I know that this false positives can be scary and disconcerting but that’s all they are – FALSE POSITIVES.
After saying all of that, I am assuming that you waited an adequate amount of time (4 months) from your last sexual encounter to getting testing done, or accuracy. Antibody takes time to develop, and if you test too soon, it will not be accurate and the low positive could be due to antibody developing but not yet fully there.
