Celiac.com 04/16/2019 (originally published 04/24/2008) - Genetic tests for celiac disease and gluten sensitivity are readily available. Testing can be performed on either blood and mouth swab samples. Tests can be done at home and mailed to the lab for analysis.
A good testing laboratory will provide an accurate prediction of celiac disease risk, and will also provide information about the statistical risk to your children, your likelihood of developing more severe celiac disease, whether one or both of your parents had the risk gene, and for some laboratories, you may determine your risk of gluten sensitivity without celiac disease.
DQ2 & DQ8 Not the Whole Story
About 95% of celiacs carry HLA-DQ2; while about 25% carry HLA-DQ8. If any part of the high risk gene ...

Celiac.com 08/22/2016 - The issue of cross-contamination keeps coming up in articles, conferences, blogs and every other venue in which celiacs discuss ways of living with our disease. For all the talk there has been precious little, if any, thoughtful analysis, so I felt it was time for one. Some will appreciate this analysis—others will not. For reference, I don't work for the food industry in any way, shape or form, so I'm not presenting arguments to help anyone make money. I just think that the way gluten permeates our food culture, we celiacs have become overly cautious and worried about where the next molecule of gluten may be hiding, ready to attack us, and as a result walk around in constant fear, significantly degrading our overall quality of our life and doing more harm to our h...

Celiac.com 06/07/2019 (originally published 07/12/2010) - Most of the gluten-free community is thrilled by the rapidly increasing public and professional awareness of our diet and the increasingly wide range of gluten-free choices available to us in supermarkets, health food stores, and even in restaurants. These are exciting times for those of us who avoid gluten. However, there are a few problems associated with the increasing public profile enjoyed by our diet. Members of the Press, and some health care professionals who have not kept up with the research, continue to voice false and faulty perceptions of our diet. The net result of these misinformed, often authoritative, statements, cautions, and prohibitions is that many individuals who might benefit from the diet are dissuaded from...

Celiac.com 04/01/2020 - Some people with celiac disease have symptoms even when they follow a gluten-free diet. Even though the most likely culprit in these cases is cross-contamination, or some other type of food sensitivity, some people have suggested that the problem may have to do with certain foods that trigger a celiac-like gut reaction. But, is that really true? 
A few years back, a team of researchers set out to figure out if such symptoms might come from either cross-contamination with gluten-containing foods, or cross-reactivity between α-gliadin and non-gluten foods eaten as part of an otherwise gluten-free diet. 
Researcher Aristo Vojdani, and colleagues with the Immunosciences Lab used ELISA and dot-blot to gauge the reactivity of affinity-purified polyclonal an...
