Gluten Free Before Blood Tests

I am going to go through the blood tests for celiac. I have been mostly off gluten for 8 weeks with almost weekly inadvertent exposure in that time frame. Will my blood tests be impacted by this? Do I need to resume daily consumption of gluten and for how long? How much is enough daily? Thanks!

Yes, return to gluten to be tested. The blood testing and biopsies are not as accurate as we would like and certainly not eating gluten could further add to that inaccuracy.

A gluten diet for a couple of months would help reek havoc to show positive antibodies. If you are unable to do that, a positive dietary response is also considered a diagnosis, although it would be difficult to classify as Celiac, gluten intolerance or allergy. But you might feel better and that's the bottom line.

When you test, make sure that this is what is ordered:

Anti-gliadin antibodies (AGA) both IgA and IgG

Anti-endomysial antibodies (EMA) - IgA

Anti-tissue transglutaminase antibodies (tTG) - IgA

Total IgA level.

Thanks for asking that question. I had been wondering the same thing, as I've only been back on gluten for a couple months and I am getting tested soon.

      It is more likely code for “we think there really was a good response to the treatment, but it was small or in a small percent of subjects so it would take a large clinical trial to try to prove it.”

      Celiac symptoms

      Thank you so much for your replies. Luckily the rash went away when I completely swore off gluten. It took several months but I have not had a flare in months. So a biopsy is no longer possible. The itch was terrible and apart from bleaching my skin the steroid lotions and potions did nothing. The Gliadin is for accidents and shall be a part of my travel kit from now on. This past exposure has made a me a little leery about eating anything that was not cooked in my kitchen or a dedicated gluten-free restaurant. As much as I used to love baked goods, I am cured and have become quite the gluten free baker to the point that friends and family forget that my cakes/cookies/and bread are not "real". I guess I will have to wait for the new blood test to come out to get confirmation but I have a suspicion that the rash was dermatitis herpetiformis.

      Hello, I just wanted to share with the frustration of skin issues and seeing dermatologist and medications not working for years, I did my own healing experiment. As of last week I have been taking a drop internally under the tongue of Vetiver and putting on topically on sores Yellow/Pom.I am seeing a extreme difference at a rapid time.Im also noticing my nails a little harder. Ive always been into natural properties because I feel its safer for the body.I know short time, but really seeing a difference. I also feel the the trapped gases that causes bloating helps break down as well.Curious if any body else can benefit from and has tried. Products is made by Doterra by Dr Hill

      Celiac symptoms

      By Scott Adams · Posted

      I agree with @trents, and the rash you described, especially its location and resistance to steroids, sounds highly characteristic of dermatitis herpetiformis, which is the skin manifestation of celiac disease. The severe and prolonged reaction you're describing five days after a small exposure is, while extreme, not unheard of for those with a high sensitivity; the systemic inflammatory response can absolutely last for several days or even weeks, explaining why you still don't feel right. Your plan to avoid a formal gluten challenge is completely understandable given the severity of your reactions, and many choose the same path for their well-being. While experiences with GliadinX (they are a sponsor here) are mixed, some people do report a reduction in the severity of their symptoms when taken with accidental gluten, though it is crucial to remember it is not a cure or a license to eat gluten and its effectiveness can vary from person to person. For now, the absolute best advice is to continue being hyper-vigilant about cross-contamination—buffets are notoriously high-risk, even with good intentions. Connecting with a gastroenterologist and a dermatologist who specialize in celiac disease is essential for navigating diagnosis and management moving forward. Wishing you a swift recovery from this last exposure. If you have DH you will likely also want to avoid iodine, which is common in seafoods and dairy products, as it can exacerbate symptoms in some people. This article may also be helpful as it offers various ways to relieve the itch:
