I have had people with false positives as high as 17. I recently had someone with a 12 not confirm. If you have no symptoms and want to be certain about your HSV 2 status, you should do the western blot. The thing is, most people who have higher positives, like yours, don’t do western blots and so we really don’t know much about exactly how many people with high positives don’t confirm.
It is very likely that an ELISA IgG would be the same. It really shouldn’t be used as confirmation.
This is a life long STI and you should be certain you are actually infected before living the rest of life either taking meds or disclosing to future partners. Your call though. If money is a big consideration, that’s real and a factor for sure.
