Gene Test

I'm thinking I might go for the gene testing since I am allergic to wheat and can't do the eating gluten thing. I really would like to know if I have the genes.

I certainly have a suspicious family history for celiac----I've had abd. cramps, bloating, and "gurgling" intestines since I was 18. My son has had recurrent mouth ulcers since childhood- (celiac symptom). My sister is anemic with gut problems too. My father (of Irish decent )had same problems as well as most of his siblings did. His own father (my grandfather ) had issues too and referred to it as the "Carr Belly " :D So apparently these bellyaches go way back ! :)

Is the test expensive--- I have insurance--- but not sure if I will ask my MD for the test or just do it myself.

Thanks !

I've been thinking about doing this, too. My parents are both Norwegian, so wondering if I have two of the genes or just one.

There are articles about genetic testing and labs on the homepage on this site. Very informative.Good luck!

My doctor uses Prometheus. I believe that there are only 3 labs int the US that are capable of doing this test:

Enterolab (which is still controversial), Prometheus and Kimball. (If I'm wrong on that, I apologize and please correct me)

The next question is how much will my insurance pay??? :huh::lol:

Many other labs do it as well - including

Quest Open Original Shared Link

Labcorp Open Original Shared Link

And most labs that your doctors office uses. Go to your doctor and ask to him to test you for HLA DQ2 and DQ8. :)

Otherwise, use Kimball Genetics - they are recommended by the Celiac Center at the University of Chicago. Open Original Shared Link

I had my testing done through AML labs which has since converted to Quest Diagnostics. It is the lab our hospital uses, my insurance covered the entire panel.

i used Prometheus. my GI doc ordered the tests and i went to a local hospital to have the blood drawn. Supposedly the doctors office and the hospital have some kind of agreement where they don't give Prometheus any patient info and all the billing is through the doctor and the hospital. i was confused as far as what that meant for me and what i'd have to pay but i bit the bullet and went ahead with the testing. i just got the initial EOB from my insurance company and sure enough, $788 was billed from the hospital. no mention of Prometheus. insurance hasn't paid yet so i don't know what is my portion. i'm hoping it's not more than a $10 or $25 co-pay.

I go to Dr. Green in NY, and he orders the tests through Kimball Genetics. I didnt end up having to pay anything at all, b/c I went through my insurance and they covered it. When you receive the tests, you can get codes for the test, so that you can contact your insurance co. and find out if they will cover it. I called before I sent in the test just to make sure. I'm not sure about the other genetic testing labs, but i've heard Enterolab is also pretty well known and respected.

https://www.celiac.com/articles/21628/1/Cel...tics/Page1.html is an article that had been in a newsletter but now it has been published on the website.

Some labs only test for DQ2 and 8, and some only for the beta chain, and those with the half gene are missed, and those with the gluten sensitive genes will just get an answer that they are negative for celiac gennes without further expnanation. Some labs have changed their testing and reporting now (those that calculate your risk now. The old way of reporting or not reporting results was ovten very confusing)

I am thinking about ordering a gene test from enterolab as I am in europe and only got the test for DQ2 and 8, and now my doctors think they excluded celiac and it is all in my head, and have referred me to the shrinks. The article comments on negative resutls, that they still cannot be used to exclude celiac like my doctors think. ( they say it si absolutely impossible for me to be celiac. My daughter is diagnosed celiac, and I have DH but without diagnosis so I disagree)

I thought I'd share my experience on gene testing again since this topic pops up from time to time. I know Kimball Labs is very respected, but they misdiagnosed me the first time they did my testing. I was a biopsy and blood test proven Celiac, and they told me that I was non DQ2 and 8. When I told them that I'd already been diagnosed, they reran the test and found DQ8. They said that it was "acting like another gene" that I had and they needed to do a more sophisticated test.

I tested my kids and myself through Enterolab, and the test results showed that Enterolab uses the American Red Cross for the gene testing. If you can't trust the American Red Cross, who can you trust? :)

jbuckeye, I have been wondering for several months now what the enterolab test said about you (assuming you did some gene tests through them)

and what genes Kimball thought you had initially.

I remember thye sent the sample on to a bigger lab and they found DQ8.

I guess Kimball used a rapid test, a commercial test kit, I found it when googling.

I guess the bigger lab actually carried out a proper test.

There is an article where it is mentioned which lab Enterolab uses, https://www.celiac.com/articles/21628/1/Cel...tics/Page1.html , Bonfils does testing for Enterolab

and see the next article Ten facts

https://www.celiac.com/authors/45/Dr.-Scot-Lewey

I was negative on a test that seems identical to kimball's test, so the question is a bit relevant to me.

Daughter is a diagnosed celiac.

Just a note, I was tested in August through Enterolab and both of my girls are being tested this month and Enterolab is currently using the American Red Cross. It is also listed on the bottom of my lab results. American Red Cross is not associated with Bonfils is it?

Hi--Kimball originally sent a letter saying I was DQ2 and 8 negative--nothing else. When they reran the test, a new letter came saying I was DQ8 positive.

Enterolab said I was DQ8 and DQ7.

My daughter is also DQ8 and DQ7.

I'm thinking that maybe DQ8 and 7 look similar/have similar actions, but genetics is WAY over my head.

Thank you, I was wondering wether I should order a gene test from enterolab. Shipping is very expensive from europe.

As far as I know, DQ7 and DQ8 are not similar, but I can look at the Wiki for DR. Looks like there are several DQ8 types, so maybe this rapid test kit is not so good for all of the DQ8 types, just the more common ones. Maybe. Just a theory.

The DR wiki page is Open Original Shared Link

I even have a link that says that DQ7 is very very similar to DQ8:

Open Original Shared Link

"Eight of the 122 celiac disease patients lacked both the heterodimer and the DRB104 alleles; therefore, we further screened the DQB1 locus to investigate if other alleles were present in association to celiac disease (2)(14). Two of these eight celiac disease patients showed the DQ2 molecule (DQB10201 allele in heterozygosis); but one of them carried also the DQB10501 allele, also found in Sardinian patients to be associated to celiac disease (15); four showed the DQ7 molecule (DQB10304 or DQB10301 alleles). Another patient carried the DQ8 molecule encoded by the DQB10302 allele, and the remaining patient had the haplotype DQB10501 in homozygosis (15). The DQ8 molecule seems to be an alternative to DQ2 in influencing susceptibility towards celiac disease, being present in up to 20% of celiac patients not bearing of DQ2 in the Mediterranean area (2)(14)(16). Our data do not support an earlier finding that HLA-DQ7 is a nonsusceptible molecule (2). In fact, DQ7 was present in 50% of our celiac disease patients in the absence of the heterodimer and of the DRB104 alleles. Because the DQ7 molecule is very similar to the DQ8 molecule, it could alternatively present similar gluten-derived peptides to restricted T cells (17). DQ7 has been detected in a few celiac disease cases in the absence of DQ2 but in association with the DRB104 alleles (18). "

I also have a link that DQ9 is very similar to DQ8

Open Original Shared Link and they say right out that both DQ7 and DQ9 are very similar to DQ8.

"The DQ8 molecule is highly homologous to two other naturally occurring alleles, DQ7 (DQA1*0301/B1*0301) and DQ9 (DQA1*0301/B1*0303). These three alleles share an identical chain (DQA1*0301) and have nearly identical

      Gluten free nuts

      By Clear2me · Posted

      Thanks for the info. I recently moved to CA from Wyoming and in that western region the Costco and Sam's /Walmart Brands have many nuts and more products that are labeled gluten free. I was told it's because those products are packaged and processed  in different  plants. Some plants can be labeled  gluten free because the plant does not also package gluten products and they know that for example the trucks, containers equipment are not used to handle wheat, barely or Rye. The Walmart butter in the western region says gluten free but not here. Most of The Kirkland and Members Mark brands in CA say they are from Vietnam. That's not the case in Wyoming and Colorado. I've spoken to customer service at the stores here in California. They were not helpful. I check labels every time I go to the store. The stores where I am are a Sh*tshow. The Magalopoly grocery chain Vons/Safeway/Albertsons, etc. are the same. Fishers and Planters brands no longer say gluten free. It could be regional. There are nuts with sugar coatings and fruit and nut mixes at the big chains that are labeled gluten free but I don't want the fruit or sugar.  It's so difficult I am considering moving again. I thought it would be easier to find safe food in a more populated area. It's actually worse.  I was undiagnosed for most of my life but not because I didn't try to figure it out. So I have had all the complications possible. I don't have any spare organs left.  No a little gluten will hurt you. The autoimmune process continues to destroy your organs though you may not feel it. If you are getting a little all the time and as much as we try we probably all are and so the damage is happening. Now the FDA has pretty much abandoned celiacs. There are no requirements for labeling for common allergens on medications. All the generic drugs made outside the US are not regulated for common allergens and the FDA is taking the last gluten free porcine Thyroid med, NP Thyroid, off the market in 2026. I was being glutened by a generic levothyroxin. The insurance wouldn't pay for the gluten free brand any longer because the FDA took them all off their approved formulary. So now I am paying $147 out of pocket for NP Thyroid but shortly I will have no safe choice. Other people with allergies should be aware that these foreign generic pharmaceutical producers are using ground shellfish shell as pill coatings and anti-desicants. The FDA knows this but  now just waits for consumers to complain or die. The take over of Wholefoods by Amazon destroyed a very reliable source of good high quality food for people with allergies and for people who wanted good reliably organic food. Bezos thought  he could make a fortune off people who were paying alot for organic and allergen free food by substituting cheap brands from Thailand. He didn't understand who the customers were who were willing to pay more for that food and why. I went from spending hundreds to nothing because Bezo removed every single trusted brand that I was buying. Now they are closing Whole foods stores across the country. In CA, Mill Valley store (closed July 2025) and the National Blvd. store in West Los Angeles (closed October 2025). The Cupertino store will close.  In recent years I have learned to be careful and trust no one. I have been deleberately glutened in a restaurant that was my favorite (a new employee). The Chef owner was not in the kitchen that night. I've had  a metal scouring pad cut up over my food.The chain offered gluten free dishes but it only takes one crazy who thinks you're a problem as a food fadist. Good thing I always look. Good thing they didn't do that to food going to a child with a busy mom.  I give big tips and apologize for having to ask in restaurants but mental illness seem to be rampant. I've learn the hard way.          I don't buy any processed food that doesn't say gluten free.  I am a life long Catholic. I worked for the Church while at college. I don't go to Church anymore because the men at the top decided Jesus is gluten. The special hosts are gluten less not gluten free. No I can't drink wine after people with gluten in their mouth and a variety of deadly germs. I have been abandoned and excluded by my Church/Family.  Having nearly died several times, safe food is paramount. If your immune system collapses as mine did, you get sepsis. It can kill you very quickly. I spent 5 days unconscious and had to have my appendix and gall bladder removed because they were necrotic. I was 25. They didn't figure out I had celiac till I was 53. No one will take the time to tell you what can happen when your immune system gets overwhelmed from its constant fighting the gluten and just stops. It is miserable that our food is processed so carelessly. Our food in many aspects is not safe. And the merging of all the grocery chains has made it far worse. Its a disaster. Krogers also recently purchased Vitacost where I was getting the products I could no longer get at Whole Foods. Kroger is eliminating those products from Vitacost just a Bezos did from WF. I am looking for reliable and certified sources for nuts. I have lived the worst consequences of the disease and being exposed unknowingly and maliciously. Once I was diagnosed I learned way more than anyone should have to about the food industry.  I don't do gray areas. And now I dont eat out except very rarely.  I have not eaten fast food for 30 years before the celiac diagnosis. Gluten aside..... It's not food and it's not safe.  No one has got our backs. Sharing safe food sources is one thing we can do to try to be safe.

      Gluten free nuts

      I wanted to respond to your post as much for other people who read this later on (I'm not trying to contradict your experience or decisions) > Kirkland Signature Super Extra-Large Peanuts, 2.5 lbs, are labeled "gluten free" in the Calif Costcos I've been in. If they are selling non-gluten-free in your store, I suggest talking to customer service to see if they can get you the gluten-free version (they are tasty) > This past week I bought "Sliced Raw Almonds, Baking Nuts, 5 lbs Item 1495072 Best if used by Jun-10-26 W-261-6-L1A 12:47" at Costco. The package has the standard warning that it was made on machinery that <may> have processed wheat. Based on that alone, I would not eat these. However, I contacted customer service and asked them "are Costco's Sliced Almonds gluten free?" Within a day I got this response:  "This is [xyz] with the Costco Member Service Resolutions Team. I am happy to let you know we got a reply back from our Kirkland Signature team. Here is their response:  This item does not have a risk of cross contamination with gluten, barley or rye." Based on this, I will eat them. Based on experience, I believe they will be fine. Sometimes, for other products, the answer has been "they really do have cross-contamination risk" (eg, Kirkland Signature Dry Roasted Macadamia Nuts, Salted, 1.5 lbs Item 1195303). When they give me that answer I return them for cash. You might reasonably ask, "Why would Costco use that label if they actually are safe?" I can't speak for Costco but I've worked in Corporate America and I've seen this kind of thing first hand and up close. (1) This kind of regulatory label represents risk/cost to the company. What if they are mistaken? In one direction, the cost is loss of maybe 1% of sales (if celiacs don't buy when they would have). In the other direction, the risk is reputational damage and open-ended litigation (bad reviews and celiacs suing them). Expect them to play it safe. (2) There is a team tasked with getting each product out to market quickly and cheaply, and there is also a committee tasked with reviewing the packaging before it is released. If the team chooses the simplest, safest, pre-approved label, this becomes a quick check box. On the other hand, if they choose something else, it has to be carefully scrutinized through a long process. It's more efficient for the team to say there <could> be risk. (3) There is probably some plug and play in production. Some lots of the very same product could be made in a safe facility while others are made in an unsafe facility. Uniform packaging (saying there is risk) for all packages regardless of gluten risk is easier, cheaper, and safer (for Costco). Everything I wrote here is about my Costco experience, but the principles will be true at other vendors, particularly if they have extensive quality control infrastructure. The first hurdle of gluten-free diet is to remove/replace all the labeled gluten ingredients. The second, more difficult hurdle is to remove/replace all the hidden gluten. Each of us have to assess gray zones and make judgement calls knowing there is a penalty for being wrong. One penalty would be getting glutened but the other penalty could be eating an unnecessarily boring or malnourishing diet.

      Has anyone had terrible TMJ/ Jaw Pain from undiagnosed Celiac?

      By trents · Posted

      Thanks for the thoughtful reply and links, Wheatwacked. Definitely some food for thought. However, I would point out that your linked articles refer to gliadin in human breast milk, not cow's milk. And although it might seem reasonable to conclude it would work the same way in cows, that is not necessarily the case. Studies seem to indicate otherwise. Studies also indicate the amount of gliadin in human breast milk is miniscule and unlikely to cause reactions:  https://www.glutenfreewatchdog.org/news/gluten-peptides-in-human-breast-milk-implications-for-cows-milk/ I would also point out that Dr. Peter Osborne's doctorate is in chiropractic medicine, though he also has studied and, I believe, holds some sort of certifications in nutritional science. To put it plainly, he is considered by many qualified medical and nutritional professionals to be on the fringe of quackery. But he has a dedicated and rabid following, nonetheless.
