Dna Testing... What's This?

I've been wheat-free for about a year and off and on before for years and now completely gluten-free for two months and feeling MUCH better.

Several years ago I had a negative biopsy (I'd been avoiding wheat, though) and more recently I had a negative blood test after not consuming wheat for at least six months. Ds was just diagnosed and his gastroentologist recommended that I get DNA testing.

Anyone know what this is about? I'm having a blood sample taken for this next week.

Thanks!

You'll get a variety of responses to this, but I suspect it's because the ge is curious.

It doesn't really tell you that much.

The vast majority of confirmed Celiacs (95%+) have one or both genes: HLA DQ2 or HLA DQ8.

Just having the gene doesn't mean you have Celiac. 1 in 133 Americans have Celiac, but about 30% of the population has the gene. Gene doesn't equal Celiac, but if you don't have the gene, you have a much, much, much lower risk (statistically) of having Celiac.

Since your son has Celiac, your doctor is doing the gene test on you to see if Celiac is a possibility.

Sounds like doctor curiosity. Your negative tests didn't mean anything because you were off gluten. It was silly for them to even test you under those circumstances.

I think you already know you have to avoid gluten. You feel better without it. What genes you have doesn't make any difference. If you don't have either celiac gene, it just means (probably) that you have nonceliac gluten sensitivity. I say probably because there are some diagnosed celiacs without a celiac gene.

But the "treatment" for celiac and NCGS are the same, don't eat gluten. Whatever your genes are you aren't going to eat gluten.

      Celiac and allergic to common subs and adds in prepared foods

      By DAR girl · Posted

      Looking for help sourcing gluten-free products that do not contain potato or corn derived ingredients. I have other autoimmune conditions (Psoriatic Arthritis and Sjogrens) so I’m looking for prepared foods as I have fatigue and cannot devote a lot of time to baking my own treats.

      Disregarded

      By Scott Adams · Posted

      I am so sorry you're going through this. It's completely understandable to feel frustrated, stressed, and disregarded after such a long and difficult health journey. It's exhausting to constantly advocate for yourself, especially when you're dealing with so many symptoms and positive diagnoses like SIBO, while still feeling unwell. The fact that you have been diligently following the diet without relief is a clear sign that something else is going on, and your doctors should be investigating other causes or complications, not dismissing your very real suffering.

      Paying for my own Celiac screening at WalkInLab so a positive result doesn’t become part of my medical history

      By Oldturdle · Posted

      It is just so sad that health care in the United States has come to this.  Health insurance should be available to everyone, not just the healthy or the rich.  My heart goes out to you.  I would not hesitate to have the test and pay for it myself.  My big concern would be how you could keep the results truly private.  I am sure that ultimately, you could not.  A.I. is getting more and more pervasive, and all data is available somewhere.  I don't know if you could give a fake name, or pay for your test with cash.  I certainly would not disclose any positive results on a private insurance application.  As I understand it, for an official diagnosis, an MD needs to review your labs and make the call.  If you end up in the ER, or some other situation, just request a gluten free diet, and say it is because you feel better when you don't eat gluten.      Hang in there, though.  Medicare is not that far away for you, and it will remove a lot of stress from your health care concerns.  You will even be able to "come out of the closet" about being Celiac!

      Yes, I've posted a few times about two companies: Request a Test and Ulta Labs. Also, pretty much we can all request any test we want (with the possible exception of the N protein Covid test and I'm sure a couple of others) with Lab Corp (or Pixel by Lab Corp) and Quest. I much prefer Lab Corp for their professionalism, ease of service and having it together administratively, at least in DC. And just so you know, Request a Test uses Lab Corp and Quest anyway, while Ulta Labs uses only Quest. Ulta Labs is cheaper than Request a Test, but I am tired of dealing with Quest, so I don't use them so much.

      Does Dailymed.nlm.nih.gov site have filters for gluten?

      By Scott Adams · Posted

      PS - I think you meant this site, but I don't believe it has been updated in years: http://glutenfreedrugs.com/ so it is best to use: You can search this site for prescriptions medications, but will need to know the manufacturer/maker if there is more than one, especially if you use a generic version of the medication: To see the ingredients you will need to click on the correct version of the medication and maker in the results, then scroll down to "Ingredients and Appearance" and click it, and then look at "Inactive Ingredients," as any gluten ingredients would likely appear there, rather than in the Active Ingredients area. https://dailymed.nlm.nih.gov/dailymed/
