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!

      @Jmartes71, Sorry you've been feeling so poorly. Are you taking any medication to treat the SIBO? Are you taking any Benfotiamine? Benfotiamine will help get control of the SIBO. Thiamine deficiency has symptoms in common with MS. Have you had your gas appliances checked for gas leaks and exhaust fume leaks? Carbon Monoxide poisoning...

      Blood Test for Celiac wheat type matters?

      European wheat is often a "soft wheat" variety which contains less gluten than "hard wheat" varieties found in the States. In European countries, different cooking methods and longer fermentation (rising or proofing) times allow for further breakdown of gluten peptides. Wheat in the States is a blend of hard and soft wheat. Gluten content can...

      Severe severe mouth pain

      From my own experience and that of others who have tried to discontinue PPI use, I think your taper down plan is much too aggressive. It took me months of very incremental tapering to get to the point where I felt I was succeeding and even then I had to rely some days on TUMS to squelch flareups. After about a year I felt I had finally won the battle. Rebound...

      Severe severe mouth pain

      Talk to your doctor about switching to an antihistamine, and supplementing essential vitamins and minerals. Dietary changes (low carb/paleo) may be beneficial for you. Have you talked to a dietician or nutritionist about a nutrient dense gluten free diet? It's harder to get all the vitamins needed from a gluten free diet. Gluten containing products are...

      Severe severe mouth pain

      I’m pretty sure they do. I have been on myfortic, tacrolimus since 2021 for my liver transplant and added prednisone after kidney transplant. I’m going to try to cut back omeprazole to 20 mg a day and then after a week try to stop altogether. Thank you for your help.

      @Jmartes71, Sorry you've been feeling so poorly.   Are you taking any medication to treat the SIBO?   Are you taking any Benfotiamine?  Benfotiamine will help get control of the SIBO.  Thiamine deficiency has symptoms in common with MS. Have you had your gas appliances checked for gas leaks and exhaust fume leaks?  Carbon Monoxide poisoning can cause the same symptoms as the flu and glutening.  Doctors have to check venous blood (not arterial) for carbon monoxide.  Are other inhabitants sick, or just you?  Do they leave the house and get fresh air which relieves their symptoms?

      European wheat is often a "soft wheat" variety which contains less gluten than "hard wheat" varieties found in the States.   In European countries, different cooking methods and longer  fermentation (rising or proofing) times allow for further breakdown of gluten peptides. Wheat in the States is a blend of hard and soft wheat.  Gluten content can vary according to where the wheat was grown, growing conditions, when harvested, and local preference, so a blend of both hard and soft wheat is used to make a uniform product.   I moved around quite a bit as a child in a military family.  I had different reactions to gluten in different areas of the country every time we moved.  I believe some wheat breeds and blends are able to provoke a worse immune response than others.   Since European soft wheat doesn't contain as much gluten as American wheat, you may try increasing your intake of your soft wheat products.  A minimum of ten grams of gluten is required to get a sufficient immunological response so that the anti-gluten antibodies leave the intestines and enter the bloodstream where they can be measured by the tTg IgA test.  Your whole wheat bread may only have a gram of gluten per slice, so be prepared...

It took me months of very incremental tapering to get to the point where I felt I was succeeding and even then I had to rely some days on TUMS to squelch flareups. After about a year I felt I had finally won the battle. Rebound is real. If I were you I would aim at cutting back in weekly increments for two weeks at a time rather than daily increments. So, for instance, if you have been taking 2x20mg per day, the first week cut that down to 2x20mg for six days and 1x20 mg for the other day. Do that for two weeks and then cut down to 2x20mg for five days and 1x20 for two days. On the third week, go 20x2 for four days and 20x1 for 3 days. Give yourself a week to adjust for the reduced dosage rather than reducing it more each week. I hope this makes sense.
