I’ve had false positives as high as 14, but not often.
The IgG test just looks for antibody to the herpes virus and generally speaking, the higher the value,the longer the infection but that isn’t true every time. I suppose it is possible that you could have gotten infected a month before this value but I would say unlikely.
If you take daily antiviral medicine and your partners use condoms regularly, the risk of transmission is quite low.
