Dna Testing For Celiac?

I kind of just want to know for my own benefit I guess. Also b/c we have kids. Could someone also explain the gene thing to me (the DQ stuff?). I googled DNA testing for celiac and a couple companies came up but am not sure if they are reputable. Thanks!

Your doctor can run the tests through the national lab companies....so you don't necessarily need to do it yourself. Quest and Labcorp are two of the most commonly used lab companies by doctors (not for Celiac, just for all bloodwork). Prometheus also offers genetic testing....all of which can be done through your dr, and potentially paid for by insurance.

The two identified genes are HLA DQ2 and HLA DQ8. The current research is the vast majority of Celiacs have one/both of the genes (95-98%)...but, of course, not all. Of those with a gene, the majority (92% or so) have DQ2. The rest have DQ8. There is research on other genes, but this is the best that we know now.

In general, the gene test will be able to give you an idea if your child is genetically predisposed to potentially having Celiac. About 1 in 133 Americans have Celiac, but 30-40% of the general population have these genes. Just having the gene does NOT mean you have Celiac. However, testing negative for the gene greatly decreases your chances of having it.

One of the benefits for children of parents who have Celiac is that then the parents know if it is more of a major worry or not. i.e., if they don't have the gene, parents might not be as worried, and won't be doing blood testing every year to check for celiac.

For those who have inconclusive blood tests/biopsies, testing for the gene can be one way to rule out Celiac.

However, testing negative for the gene doesn't mean that someone won't have non-Celiac problems with gluten.

I was genetically tested (DQ8) and our one-day kids will be tested right away.

I had myself tested through Enterolab. I was already diagnosed, but was curious about my genes and also wanted to know for my sons.

It was $169 total out of pocket. My results are in my signature :)

I also recommend Enterolab.com because they also test for the gluten intolerant genes. I think in the coming years it is going to be important to know which one of those genes that you have...

Other labs only test for DQ2 & DQ8 - a total shame...

Ditto for Enterolab. I just attended a lecture by Dr. Fine, who started Enterolab. He was 1000% credible, and I was hugely impressed by his story. He's an incredibly knowledgeable individual who is quite passionate about this topic. Enterolab is a non-profit, by the way. Dr. Fine wanted to make testing available and affordable to people who were not getting answers from their doctors. People like ME, for example!!

Any nagging doubts I may have had about Enterolab were dispelled after I attended this lecture.

      Clearly from what you've said the info on Dailymed is much more up to date than the other site, which hasn't been updated since 2017. The fact that some companies might be repackaging drugs does not mean the info on the ingredients is not correct.

      To evaluate the TTG antibody result we’d need to know the normal range for that lab.  Labs don’t all use the same units.  However, based on any normal ranges that I’ve seen and the listed result being greater than a number rather than a specific number, I’d say yes, that is high! Higher than the range where the test can give a quantitative result. You got good advice not to change your diet yet.  If you went gluten free your intestines would start to heal, confusing any further testing,

      Scott is correct….Thank you for catching that!      Direct link for info  of fillers.    http://www.glutenfreedrugs.com/Excipients.htm Link is on 2nd page  of www.glutenfreedrugs.com   Site was started by a pharmacist (or 2) maybe 15-20 yrs ago with LAST updated in  2017.  This makes it’s Drug List so old that it’s no longer relevant. Companies & contacts, along with suppliers &  sources would need to be referenced, same amount effort  as starting with current data on DailyMed      That being said, Excipient List is still be relevant since major changes to product labeling occurred prior ’17.           List is the dictionary that sources the ‘foreign-to-us’ terms used on pharmaceutical labels, terms we need to rule out gluten.    Note on DailyMed INFO— When you look for a specific drug on DailyMed, notice that nearly all of companies (brands/labels) are flagged as a ‘Repackager’… This would seem to suggest the actual ‘pills’ are being mass produced by a limited number of wholesaler suppliers (esp for older meds out of  patent protection.).      If so, multiple repackager-get  bulk shipments  from same supplier will all  be selling identical meds —same formula/fillers. Others repackager-could be switching suppliers  frequently based on cost, or runs both gluten-free & non- items on same lines.  No way to know  without contacting company.     While some I know have  searched pharmacies chasing a specific brand, long-term  solution is to find (or teach) pharmacy staff who’s willing help.    When I got 1st Rx ~8 years ago, I went to Walgreens & said I needed gluten-free.  Walked  out when pharmacist said  ‘How am I supposed  to know…’  (ar least he as honest… ). Walmart pharmacists down the block were ‘No problem!’—Once, they wouldn’t release my Rx, still waiting on gluten-free status from a new supplier. Re: Timeliness of DailyMed info?   A serendipitous conversation with cousin in Mi was unexpectedly reassuring.  She works in office of Perrigo, major products of OTC meds (was 1st to add gluten-free labels).  I TOTALLY lucked out when I asked about her job: “TODAY I trained a new full-time employee to make entries to Daily Med.’  Task had grown to hours a day, time she needed for tasks that couldn’t be delegated….We can only hope majorities of companies are as  conscientious!   For the Newbies…. SOLE  purpose of  fillers (possible gluten) in meds is to  hold the active ingredients together in a doseable form.  Drugs  given by injection or as IV are always gluten-free!  (Sometimes drs can do antibiotics w/ one-time injection rather than 7-10 days of  pills .) Liquid meds (typically for kids)—still read labels, but  could be an a simpler option for some products…

      So I recently had allergy testing for IGE antibodies in response to foods. My test results came back positive to corn, white potatoes, egg whites. Tomatoes, almonds and peanuts to name a few.  I have had obvious reactions to a few of these - particularly tomatoes and corn- both GI issues. I don’t really understand all this allergy versus celiac stuff. If the food allergies are mild do I have to avoid these foods entirely? I don’t know what I will eat if I can’t  have corn based gluten free products

      We have four children (7-14 yo), and our 7 year old was diagnosed with NCGS (though all Celiac labs were positive, her scope at 4 years old was negative so docs in the US won't call it celiac). We have started her on a Gluten Free diet after 3 years of major digestive issues and ruling out just about everything under the sun. Our home and kitchen and myself are all gluten-free. But I have not asked my husband/her dad or her other siblings to go completely gluten-free with us. They are at home, but not out of the home. This has led to situations when we are eating out where she has to consistently see others eating things she can't have and she has begun to say "Well, I can't have <fill in the blank>...stupid gluten."  How have you supported your gluten-free kiddos in the mental health space of this journey, especially young ones like her. I know it's hard for me as an adult sometimes to miss out, so I can't imagine being 7 and dealing with it! Any tips or ideas to help with this?
