Please help- eating gluten-free during testing?

Do you need to be eating gluten for a Gliadin blood test? My doc says you don't but I'm not convinced? 

Basically I had a Tissue Trang IGA test which came back negative. I then started eating gluten-free while waiting for test results for EMA IGG (as was low in IGA) as I was convinced it would come back positive and it took weeks to hear anything... but it came back negative. I have been awfully ill with weight loss, abdominal pain, fatigue, joint pain, burning all over and my symptoms have mildly improved on a gluten- free diet but I don't have a diagnosis and realised now that I could have had a Gliadin test too. I'm not sure what to do because I'm severely underweight and don't want to do my body more harm by eating gluten again? Any advice would be appreciated.

All blood test checking for antibodies like that require you to be eating the offensive product for 12 weeks daily.
Some people do test negative on the test but still have the damage, another route would be to only eat gluten for 2 weeks daily and get the endoscope with biopsies done to check for intestinal damage.

I’d you can, consider  a Gastroenterologist (GI) consult.    You could have celiac disease or something else like Crohn’s.  A GI is your best bet.  

How low was your Immunoglobulin A result?  It really has to be close to zero for the test not to work, but then again, there are always anomalies (like me) who do not test positive to the TTG and I am not IgA deficient and I am biopsy confirmed for celiac disease.

      Buckwheat

      I agree, there can be contamination at many points--milling is another possible source of contamination for any flours.

      Keep in mind that with manufactured food products, "gluten free" doesn't equate to no gluten. Things that are naturally gluten free can be cross-contaminated with gluten in the field, in shipping and in processing. In the U.S. companies can use the gluten free label as long as the product doesn't exceed 20ppm of gluten. That amount still may cause a reaction in some people.

      Inconclusive results

      By deanna1ynne · Posted

      Dd10 was tested for celiac four years ago bc two siblings were dx’d (positive labs and biopsies). Her results at the time were positive ema  and ttg (7x the UL), but a negative biopsy. We checked again three months later and her ttg was still positive (4x the UL), but ema and biopsy were negative. Doc said it was “potential celiac” and to keep eating gluten, but we were concerned about harming her growth and development while young and had her go gluten-free because we felt the labs and ema in particular were very suggestive of early celiac, despite the negative biopsies. She also had stomach aches and lethargy when eating it. We just felt it’d be better to be safe than sorry. Now, four years later, she doesn’t want to be gluten-free if she doesn’t “have to be,” so underwent a 12 week gluten challenge. She had labs done before starting and all looked great (celiac panel all negative, as expected.) Surprisingly, she experienced no noticeable symptoms when she began eating gluten again, which we felt was a positive sign. However, 12 weeks in, her labs are positive again (ttg 4x the UL and ema positive again as well). Doc says that since she feels fine and her previous two biopsies showed nothing, she can just keep eating gluten and we could maybe biopsy again in two years. I was looking up the ema test and the probability of having not just one but two false positives, and it seems ridiculously low.  Any advice? Would you biopsy again? She’s old enough at this point that I really feel I need her buy-in to keep her gluten-free, and she feels that if the doc says it’s fine, then that’s the final word — which makes me inclined to biopsy again and hope that it actually shows damage this time (not because I want her to have celiac like her sisters, but because I kind of think she already does have it, and seeing the damage now would save her more severe damage in the long run that would come from just continuing to eat gluten for a few more years before testing again.)  Our doc is great - we really like him. But we are very confused and want to protect her. One of her older sibs stopped growing and has lots of teeth problems and all that jazz from not catching the celiac disease sooner, and we don’t want to get to that point with the younger sis. fwiw- she doesn’t mind the biopsy at all. It’s at a children’s hospital and she thinks it’s kind of fun. So it’s not like that would stress her out or anything.

      Thanks for the replies. I already use a gluten-free brand of buckwheat flakes I occasionally get itchy bumps. I'm still reviewing all my food products. I occasionally eat prepackaged gluten-free crackers and cookies, so I'll stop using those. I use buckwheat flakes and Doves Farm flour as a base for baking. Would you recommend eliminating those as well? It's a constant search.

      Frequent nausea after gluten-free diet

      By Wheatwacked · Posted

      Gluten free food is not fortified with vitamins and minerals as regular food is.  Vitamin deficiencies are common especially in recently diagnosed persons,  Get a 25(OH)Vitamin D blood test. And work on raising it.  The safe upper blood level is around 200 nmol/L.    "Low serum levels of 25(OH)D have been associated with increased risk of autoimmune disease onset and/or high disease activity. The role of vitamin D in autoimmune diseases   🏋️‍♂️Good job!   I find the commercial milk will give me mild stomach burn at night, while pasture/grassfed only milk does not bother me at all.  While you are healing, listen to your body.  If it hurts to eat something, eat something else.  You may be able to eat it later, or maybe it is just not good for you.  Lower your Omega 6 to 3 ratio of what you eat.  Most omega 6 fatty acids are inflammation causing.    The standard american diet omega 6:3 ratio is estimated at upward of 14:1.  Thats why fish oil works
