Testing for Celiacs

Hi all

I was wondering if anyone diagnosed celiacs disease has experience a similar situation to mine.

I do not eat gluten free (yet) and have symptoms of celiacs or IBS. The usual type of symptoms - bloating, cramps etc.

I had two tests performed:

1.) duodenal biopsy (via endonoscopy) which showed some signs of celiacs as there was villous atrophy

2.) celiac serology (blood test) which was negative for celiacs disease 

Has anyone else found themselves in a similar situation and if so how did they manage it? 

My Gastro was not clear on whether I have celiacs and instead suggested an elimination diet to see if that will help so I plan to go gluten free, however, I am wondering how common this scenario is and how likely it is I actually have celiac given the biopsy results.

Thanks

Welcome to the forum, Alikat77!

Yes, we have numerous reports on the forum of people who test positive for villous atrophy and but are negative for blood antibody testing. Often this happens when only one antibody test is run from the several that can be run. Typically, physicians will run only the tissue Transglutaminase  IGA (aka,, tTG-IGA). It is the most popular blood test, combining relatively good sensitivity with relatively good specificity. And it is relatively inexpensive. But it can miss about 20% of people from white European extraction and about 80% of those from black African descent who actually do have celiac disease as confirmed by biopsy.  We wish physicians would run a "full celiac panel" to cover these antibody testing anomalies. Here is a primer: https://celiac.org/about-celiac-disease/screening-and-diagnosis/screening/.

The biopsy of the villous lining is considered to be the gold standard of celiac diagnostic testing. The gastro doc's suggestion of trying a gluten free diet is a good one but keep in mind if you go gluten free now you would need to go back on gluten for 6-8 weeks to ensure that any future antibody testing would be valid. And typically, once you go off of gluten and try to go back on you will have more dramatic reactions to it.

I agree with @trents and if I were in your shoes I would follow your doctor's advice and try a gluten-free diet for a few months and if your symptoms go away I would consider myself as having celiac disease. Here is some info that may be helpful:

      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:
