your IgG isnt that bad mines was in the thousands and my igA was 200+ and my igm was nonexistant. the good news is that this isnt a chronic case because if you had this issue as long as some of us on this site the igM wouldnt show. IgM hows up on fresh cases.
when you start treating candida it gets worse and the immunity will go up because candida gets more aggressive. plus the immune system goes into a different gear when you start treating candida. I got sicker once i started actually fighting candida when i started. so all i can say is prepare for the ups and downs with this issue.
