<<Disclaimer: Verify this information before applying it to your situation.>> Dear members, Thank you for all of your thoughtful responses. As a refresher, I am a non-diagnosed celiac living great gf for 11/2 years. My five year old daughter has had intermittent diarrhea and abdominal pain without illness for two months. Blood work was done, with only IGG positive of 69. Replies received: From a prominent medical lab: IGG is a marker for gluten sensitivity and the need for a gluten free diet. Implied that there was no other reason for the high IGG My child's Pediatric GI which she saw for the first time, said that a friend of hers does research on celiac and that with only high IGG, she has been using a marker of anything over 40, should have endoscopy. (So 69 is very high) From a mother with celiac, who has several children, IGG only high, both were negative to endoscopy. Said that many things cause high IGG, including allergies, illness, nothing at all, even. Another mother said she regretted not having her child biopsies when it might have shown positive results. Now, it is so hard to go back and change the diet etc. A couple of members suggested that both my daughter and myself need to find out if we have IGA deficiency. I don't believe that she was tested for that. And finally,several of you have similar situations and asked for any information that I may find out , I will email again when I have more information. Thank you Maria
