<<Disclaimer: Verify this information before applying it to your situation.>> Hi everyone, I'm a mom with a celiac 5 yr old boy. My son has been gluten free for 11 months. I do everything that I know to do to strictly adhere to the diet. I either make it myself from scratch, find it on a list, call the companies, and check labels or my son doesn't have it. He is very, very good about his diet too. I'm very certain he isn't "sneaking" or anything. His teachers and other family members have all said how good he is about asking before he eats things, and I have very good cooperation from him. (I'm blessed with that, I know.) I also have separate butter dishes, jam, peanut butter, toasters, etc., anything that could be cross-contaminated, we're careful with. Now, having said all that, here's my question. We had a follow-up visit with the pediatrician to see how he was doing, and she did the gliadin blood test to see if we were doing good enough with the diet. He was initially diagnosed with the endomysial antibody test, so I have no way to compare what he was from diagnosis. But I'm at a loss as to why his IgG antibodies were still "weakly positive". This is what the results say: GLIADIN Ab IgG 1.2 Unit: GIV GLIADIN Ab IgA 0.2 Unit: GIV Reference range: Less than 0.9 GIV . . . . None Detected 0.9 - 1.1 GIV . . . . . . . . Indeterminant 1.2 - 1.6 GIV . . . . . . . . Weakly = Positive 1.7 - 3.0 GIV . . . . . . . . Positive Greater than 3.0 GIV . . Strongly Positive The doctor is telling us that she thinks he's still getting gluten from somewhere for the IgG to still be "weakly positive" after 11 months. However, I've visited with another mom of a celiac who said that the IgG antibodies can stay in the system for up to 2 years, and she wouldn't be concerned with a weakly positive result, especially if the IgA was basically zero. So, for all you parents out there who feel as responsible for your kids health as I do, tell me what you know about this. Did you have followup blood tests after diagnosis, and what about these antibodies? I feel like I need to get to the bottom of it. Either these antibodies are "residual" antibodies, or my son is getting gluten from somewhere, and I've got a lot of detective work to do. The thought of that has brought me to tears. What have your doctors told you? Thanks for your help, Jan in Idaho
