Hello to all. I am new to this wonderful site, but not new to the CFS/other??/diagnose-me merry-go-round! I'm wondering if someone could comment regarding EBV IGG titers, specifically, what is considered high? I know that something like 90 percent of the population will test positive for this, but I can't remember (imagine that!) what is considered *high* by general standards. I was told that the number really doesn't mean anything, but I'd still like some input. My test awhile back was 1:5120. Any thoughts?
