Negative Blood Test But Visible Damage?

Eggs

Hi again! Just had some testing. Am a little confused and would appreciate input. 

My lab results were basically negative (deamidated gliadin abs, iga was one point above the reference range, everything else normal), but I had only been eating gluten again for 4 weeks after my doctor drew them after 2 months gluten free. He ordered a biopsy too because in addition to having symptoms that could be celiac disease I have Sjogren's so am at a higher risk. 

I haven't seen the doctor since I got the blood test results (I saw them online), but I just had the endoscopy Wednesday (after 7 weeks back on gluten). No biopsy results yet, but the doctor said he saw damage in my intestine consistent with celiac disease. But he didn't say I have celiac disease. Was he just covering his bases by refusing to commit or is there really a chance that the biopsy comes back negative? I'm worried that my uneventful blood work is going to cause a problem with the diagnosis. My GI told me he's had patients with on-the-fence biopsies and negative blood results who he decided didn't have celiac disease. Does anyone have any input? Can you have visible damage and a negative biopsy and negative blood work?

Thanks for any input!

It can take time to build up antibodies in your blood.  That's why celiac experts recommend 8 to 12 weeks of consuming gluten prior to the blood draw.  I am sorry that your doctor did not follow the GI Association's (American, British or Canadian) protocol for celiac disease diagnostics.

It is no wonder that your GI has patients "on the fence".  Perhaps, it is time to get another doctor or at least a second opinion from a more celiac-savvy GI?  

In any case, wait for the biopsies.  I know that it is hard to be patient.  Remember, villi damage can be attributed to many things besides celiac disease.  Without a positive blood test, it is hard to have a definitive diagnosis.  But....you can always test by going gluten-free for six months and gauge how you feel.  Not the best solution, but the bottom line is that you want your health to improve.

I'm quoting you:

 (deamidated gliadin abs, iga was one point above the reference range, everything else normal)

 

You had a positive blood test period! That one positive can not be ignored. A positive is a positive even if it isn't sky high. This is more significant in light of your having only been back on gluten for 4 weeks.

      confirmed via biopsy, quite depressed

      i am australian. we do have plenty of substitutes, but most are very expensive compared to the originals. i believe i'll just stick to home cooked meals and not have many treats at all. it's sad but it's just so much easier. also, ive heard far too many horror stories of people ordering gluten free food from restaurants and cafés, explicitly telling servers and kitchen staff that cross contamination is a strict no go, and they still get very sick. until i find a reasonably priced fully gluten free kitchen somewhere, i am not eating out for my safety and sanity.

      Gluten Sensitivity

      By The Logician · Posted

      To Trent’s, yes, from what i’ve read it is not uncommon for digestive systems to become less tolerant to gluten over time. Many types of sensitivity or allergies arise in older people who never had a problem. I don’t see why you are focusing on anything but the fact that after years of my sensitivity to gluten, for whatever reason , it has disappeared after a bout of antibiotics. What i’ve read is antibiotics can make gluten sensitivity worse. In any event, in my case, if I can still eat all the wheat products I want with no reaction after a month or more since my hospital stay this is something that should be investigated. Time will tell.

      I had a UTI, blood cultures are standard to insure that the infection does not get in the bloodstream which can lead to sepsis and death. In my case there was bacteria in my blood which necessitated 48 hours of antibiotic IV

      Finally got in to doctor to get my referral and I lucked out and got into Gastro the same day - question about different transglutaminase results

      Hi Cameo674. just read your post. Well wishes to a correct diagnosis so that you can get on track to healing and feeling better. Personally I know it’s good to have the eosinophilic disorder ruled out too, as this can show anti-ttg igA antibodies too. But usually without the anti-gliadin antibodies unless gliadin is an allergen for you. Thanks for posting the link to look up SNPs rs… numbers on another post. Was useful. Looking at your result, ”Celiac Associated HLD-DQ Typing: DQA1* Value: 05; DQA1*DQA11 Value: 05; DQB1* Value: 02; DQB1-DQB11 Value: 02; Celiac Gene Pairs Present Value: Yes; Celiac HLA Interpretation Value: These genes are permissive for celiac disease.  However, these...
