<<Disclaimer: Verify this information before applying it to your situation.>> Hello Can someone please help me. I took the anti-giadin assay IgG and I tested at 34. My nerologist said that is a moderate to high positive, my GI doc said it is totally normal and based on my negative biopsy, said he feels sure gluten is not my issue, when I think it is. HELP PLEASE. Does anyone know the range, I can't find it anywhere? RED *Support summarization of posts, reply to the SENDER not the CELIAC List*
