"GEMINI raises an important point about elevated levels, even with dietary compliance. The diabetes may be why the levels are still reading high and in time, they will come down ---as both she and Peter suggest. I find it interesting that the information from the CDC website concludes with--and \"in many healthy people, too.\"  We often say \"there are no false positives\" on here, but it would seem that isn't entirely true. YES, it is 100% specific for celiac disease--yet, OTHER conditions apparently cause this to occur--which means the doctor would have to be pretty AI disease- savvy to figure it out.   \n\n \n\nfrom Celiac Disease Center at Columbia University \n\n \n\n\"Causes of false positive celiac serologic tests \n\n \n\nThe endomysial antibody test is virtually 100% specific for celiac disease. However anti-tTG has been reported to be positive in the presence of liver disease, especially cirrhosis [33], diabetes [34, 35] and severe heart failure [36], as well as arthritis [37] and various autoimmune disorders [38]. The use of human tTG as the antigen in the test kit adds some greater specificity. Antigliadin antibodies may be present in inflammatory bowel disease [39], collagen vascular disease [40], and in many healthy people as well [41].\" \n"
