<<Disclaimer: Verify this information before applying it to your situation.>> Thank you to all that responded. I should have been more specific to ask about tests to determine accidental gluten ingestion in follow up appointments. No consensus, but several recommendations to use the tTG and/or the test that was the highest indicators of gluten ingestion prior to diagnosis. Lindsay Specific comments: · Blood test will be positive if not consuming gluten · We were just at the U of MD Center for Celiac Research and Dr. Fasano is running the the whole tTG and the EMA on my son as follow up. · The best test for follow up is individualized. Whatever test was highest when you had the celiac panel when you were diagnosed, is the one you should have done for followup · I truly don't believe there are any accurate tests for low levels of gluten in the diet. I got really sick for several months a few years ago. I couldn't figure out why, so thought I'd do a blood test to see if I was accidentally getting some gluten from some hidden source. The antigliadin tests came out negative. That supposedly meant I wasn't ingesting any gluten. However soon after I got the results, I finally discovered the source of the gluten. It was in a seasoned salt I put on my chicken two or three times a week. The company changed their recipe w/o changing their labeling. When I stopped using the seasoned salt. I got well. So I knew I had been exposed to low levels of gluten for five months, but the blood works said I hadn't. From that experience, I don't trust blood work to screen for compliance to the GF diet. They are simply not sensitive enough to detect low level gluten exposure. * Visit the Celiac Web Page at www.enabling.org/ia/celiac/index.html *
