Question About Dh Testing...

Ok, I'm not exactly sure the right way to ask my question. Me and my girls all get an itchy rash when we're accidentally glutened but it doesn't typically seem to last all that long. Is there a way to test for DH if there isn't an active lesion? Also, if we did get tested when there's an active rash would it be accurate since we're on a strict gluten free diet?

You can get false negatives with the DH rash biopsy if you are gluten free. And sometimes it is a false negative even if you are consuming gluten.

I don't they can biopsy unless you have a rash...and the biopsy would be taken from the clear skin next to the lesion.

Hmmm wonder if IgA antibodies could be detected in the clear skin where a rash used to be?

But I doubt any physician would order or perform that biopsy.

Long ago Dr.'s would diagnose DH by placing a Iodine soaked bandage over the area for 24 hrs. and if a rash developed it was diagnostic of DH. I don't know if it works though.

I suppose the value of a test would to eliminate some 'other' skin condition or allergy.

Many of us are happy to know that if there is a 1:1 corelation between gluten and rash, then we've got DH.

Thanks for the replies. I'm pretty positive DD2's rash is DH. Last week we got some cross contamination and I got hives and a couple rashy bumps on my face and DD1 was itching her stomach and back and got a little bit of a rash on her bottom, but DD2's was the worst! She got this awful rash all over her but that she was clawing at and the other morning she woke up and was crying pointing to her diaper, I took it off and saw several blisters. I think I'm going to hold off on any testing for now since she's only 21 months but it is confirmation for sure that this gluten intolerance she has is serious. Thanks again!

      Increased intraepithelial lymphocytes after 10 yrs gluten-free

      Hi @Atl222 As @trents points out, there could be many reasons for this biopsy result. I am interested to know, is your gastroenterologist concerned? Also, are your blood tests showing steady improvement over the years? I remember when I had my last biopsy, several years after diagnosis, mine came back with with raised lymphocytes but no villous...

      Increased intraepithelial lymphocytes after 10 yrs gluten-free

      Welcome to the celiac.com community, @Atl222! Yes, your increased lymphocytes could be in response to oats or it could possibly be cross contamination from gluten that is getting into your diet from some unexpected source but not enough to damage the villi. And I'm certain that increased lymphocytes can be caused by other things besides celiac disease...

      Brown Rice Vinegar (organic) from Eden Foods is likely gluten free

      This is a solid, well-reasoned approach. You’re right that “koji” by itself doesn’t indicate gluten status, and the risk really does come down to which grain is used to culture it. The fact that you directly contacted Eden Foods and received a clear statement that their koji is made from rice only, with no wheat or barley, is meaningful due diligence—especia...

      nothing has changed

      Seven months can still be early in celiac healing, especially if you were mostly asymptomatic to begin with—symptoms like low iron, vitamin D deficiency, nail changes, and hair issues often take much longer to improve because the gut needs time to recover before absorption normalizes. A tTG-IgA of 69 is not “low” in terms of immune activity, and it can t...

      Hi @Atl222 As @trents points out, there could be many reasons for this biopsy result.  I am interested to know, is your gastroenterologist concerned?  Also, are your blood tests showing steady improvement over the years? I remember when I had my last biopsy, several years after diagnosis, mine came back with with raised lymphocytes but no villous damage, too! In my own case, my consultant wasn't remotely concerned - in fact, he said I might still get this result even if all I ever did was eat nothing but rice and water.   My coeliac blood tests were still steadily improving, albeit slowly, which was reassuring.

      Welcome to the celiac.com community, @Atl222! Yes, your increased lymphocytes could be in response to oats or it could possibly be cross contamination from gluten that is getting into your diet from some unexpected source but not enough to damage the villi. And I'm certain that increased lymphocytes can be caused by other things besides celiac disease or gluten/oats exposure. See attachment. But you might try eliminating oats to start with and possibly dairy for a few months and then seek another endoscopy/biopsy to see if there was a reduction in lymphocyte counts.

The fact that you directly contacted Eden Foods and received a clear statement that their koji is made from rice only, with no wheat or barley, is meaningful due diligence—especially since Eden has a long-standing reputation for transparency. While the lack of gluten labeling can understandably give pause, manufacturer confirmation like this is often what people rely on for traditionally fermented products. As always, trusting your body after trying it is reasonable, but based on the information you gathered, your conclusion makes sense.

      Seven months can still be early in celiac healing, especially if you were mostly asymptomatic to begin with—symptoms like low iron, vitamin D deficiency, nail changes, and hair issues often take much longer to improve because the gut needs time to recover before absorption normalizes. A tTG-IgA of 69 is not “low” in terms of immune activity, and it can take 12–24 months (sometimes longer) for antibodies and the intestinal lining to fully heal, particularly in teens and young adults. Eating gluten again to “test” things isn’t recommended and won’t give you clear answers—it’s far more likely to cause harm than clarity. Weight not changing is also very common in celiac and doesn’t rule anything out. Please know that your frustration and sadness matter; this adjustment is hard, and feeling stuck can really affect mental health. You deserve support, and if you can, reaching out to a GI dietitian or mental health professional familiar with chronic illness could really help you through this phase. This study indicates that a majority of celiacs don't recover until 5 years after diagnosis and starting a gluten-free diet: Mucosal recovery and mortality in adults with celiac disease after treatment with a gluten-free diet However, it's also possible that what the study really shows is the difficulty in maintaining a 100% gluten-free diet. I suspect that if you looked closely at the diets of those who did not recover within 2 years might be that their diets were not 100% gluten-free. Perhaps they ate out more often, or didn't understand all of the hidden ingredients where gluten can hide. Either way, it shows how difficult recovery from celiac disease can be for most people.
