All of the readily available tests are run on the machine that is automated. Each western blot is done by hand and read by three different people to assure consistency. It will never be mechanized. I have seen 10 false negatives on the western blot in my career and some of them were from people who had taken antiviral therapy before we knew it could influence the blot. Some also did not wait 12 weeks. The western blot picks up 99% of HSV-2 and 96% of HSV one.
Once you test falsely positive on an IgG test, in my experience, you will continue to do so. Some people dip into the negative range from time to time as well.
