Best Genetic Tests?

I would love to hear some opinions as to what are the best genetic test kits on the market for testing for the celiac/gluten genes? Which ones are the most extensive? Thank you!

i had mine done through enterolab (which on the results said testing was done through american red cross). got the "best deal" package or something like that but they offer genetic only testing.

Promethus is testing both alpha and beta chains, so you find out if you have the high-risk DQ2.5. I'm not sure Enterolab does that.

This is a pretty important factor. Anyone who has done the Enterolab test know if they test both parts?

no, just one ... its in their FAQ area of their website i believe and i think i remember it *may* tell why they only do one portion. :)

Yes, genetic testing is only a percentile of probability, nothing more. And it's certainly not diagnostic. It CAN be used as a piece of a puzzle, but not solely independent.

I have never been a fan of Enterolabs, but I do understand that it can offer a piece to that puzzle...AFTER, other avenues have been exhausted.

Each have their own advantages.

Enterolab (Red Cross) tests by serology, and only beta chains, to keep costs down.

This is very accurate (someone here had DQ8 which a reputable lab missed, but Enterolab found it) , and you get to know all your DQ types. The other labs only look for DQ2 or DQ8.

Enterolab does test for DQ2,5, which is 0201. They can discriminate between DQ2,2 and DQ2,5. DQ2,2 is 0202.

Hi all- I just got my results back and it was done (or reported by) Quest. I don't have the official report yet- just the doctor's lab report, but mine said the following:

HLA-DQ2

(DQA1*05/DQB1*02) Positive

HLA-DQ8

(DQA1*03/DQB1*0302) Negative

HLA-DQA1* 02

HLA-DQA1* 05

HLA-DQB1* 0201

HLA-DQB1* 0202

------------------------------------------

Question-and help!: Which type of testing was this (serological?) - and could other labs do more "typing" or present more information? It looks like they tested for just the DQ2/DQ8- or did they do more (what are the 4 sets underneath the positive/negative lines)? Do I need to know more (like if they only look for HLA-DQ2 and HLA-DQ8, and one is negative, could there be one of the others - or is this all I need to know?) Does anyone know where we can learn more about interpreting these test results? For instance, people with homozygous vs. hetrozygous sets of these "phenotypes" may put some at higher risks for refractory celiac disease and for lymphoma. Thanks so much for your insight to this!

      This is a very common question, and the most important thing to know is that no, Guinness is not considered safe for individuals with coeliac disease.

      Gluten Issues and Vitamin D

      Interestingly, this thought occurred to me last night. I did find that there are studies investigating whether vitamin D deficiency can actually trigger celiac disease. Source: National Institutes of Health https://pmc.ncbi.nlm.nih.gov/articles/PMC7231074/

      Guinness, can you drink it?

      Before being diagnosed coeliac I used to love Guinness. Being made from barley it should be something a coeliac shouldn’t drink. But taking to another coeliac and they can drink it with no ill effects and have heard of others who can drink it too. is this everyone’s experience? Can I drink it? I get dermatitis herpetiformis and don’t get instant react...

      Taking Probiotics but Still Getting Sick After Gluten – Advice?

      NCGS does not cause damage to the small bowel villi so, if indeed you were not skimping on gluten when you had the antibody blood testing done, it is likely you have celiac disease.

      Guinness, can you drink it?

      By Scott Adams · Posted

      This is a very common question, and the most important thing to know is that no, Guinness is not considered safe for individuals with coeliac disease. While it's fascinating to hear anecdotes from other coeliacs who can drink it without immediate issues, this is a risky exception rather than the rule. The core issue is that Guinness is brewed from barley, which contains gluten, and the standard brewing process does not remove the gluten protein to a level safe for coeliacs (below 20ppm). For someone like you who experiences dermatitis herpetiformis, the reaction is particularly significant. DH is triggered by gluten ingestion, even without immediate gastrointestinal symptoms. So, while you may not feel an instant stomach upset, drinking a gluten-containing beer like Guinness could very well provoke a flare-up of your skin condition days later. It would be a gamble with a potentially uncomfortable and long-lasting consequence. Fortunately, there are excellent, certified gluten-free stouts available now that can provide a safe and satisfying alternative without the risk.

      I will assume you did the gluten challenge properly and were eating a lot of gluten daily for 6-8 weeks before your test, but if not, that could be the issue. You can still have celiac disease with negative blood test results, although it's not as common:  Clinical and genetic profile of patients with seronegative coeliac disease: the natural history and response to gluten-free diet: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5606118/  Seronegative Celiac Disease - A Challenging Case: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9441776/  Enteropathies with villous atrophy but negative coeliac serology in adults: current issues: https://pubmed.ncbi.nlm.nih.gov/34764141/  Approximately 10x more people have non-celiac gluten sensitivity than have celiac disease, but there isn’t yet a test for NCGS. If your symptoms go away on a gluten-free diet it would likely signal NCGS.
