"What is a gluten challenge?

A gluten challenge is the period of time when gluten is added back into a person’s diet to assist in the diagnosis of celiac disease. Antibodies take time to build into the blood stream before they can be detected through blood analysis. For a gluten challenge we recommend eating 1/2 slice of bread or a cracker each day for the duration of the challenge.

  • Prior to blood testing we recommend 12 weeks of eating gluten.
  • Prior to an endoscopic biopsy we recommend 2 weeks of eating gluten.

In the case of a severe reaction to gluten, a medical professional may opt to shorten the 12-week challenge and move immediately to an endoscopic biopsy."

I've been eating gluten for pretty much my entire life except for these past 2 weeks which I've decided to go glutenfree to potentially help another autoimmune disease I have. But now I'm curious as to whether I really have Celiac so I'm thinking to go in for a blood test. Do I have to continue eating gluten for the next 12 weeks, or it is okay to just go in now since I've only been gluten free for a short amount of time?

No one can really say.  Lots of people still have high antibodies after a few months gluten-free.  Its hard to know how your body is reacting.

I would continue to eat it and get blood tested (as already described by Karen) to be sure. If the test were negative would you always wonder if it was a false negative? I would... just a thought.

      Trying to read my lab results

      By trents · Posted

      You have three celiac disease specific antibody tests that are positive: Endomysial  Antibody IGA (aka, EMA), tTG-IGA, and tTG_IGG. Furthermore, your Immunoglobulin A at 55 is low, meaning you are IGA deficient. This one is not an antibody test for celaic disease per se but a measure of "total IGA" levels and if low (yours is low) it can suppress the individual antibody scores and even cause false negatives. So, yes, it definitely looks like you have celiac disease.   Do not yet begin a gluten free diet as your physician may refer you to a GI doc for an endoscopy/biopsy of the small bowel lining for confirmation of the antibody testing. This may help:

      Trying to read my lab results

      By Bayb · Posted

      Hi, I received my labs via email yesterday and have not heard back from my doctor yet. Can anyone tell me if these results indicate I have Celiac?      Endomysial Antibody IgAPositive  Ft-Transglutaminase (tTG) IgA6  H0-3 (U/mL) - Negative 0 - 3 - Weak Positive 4 - 10 - Positive >10 - Tissue Transglutaminase (tTG) has been identified as the endomysial antigen. Studies have demonstrated that endomysial IgA antibodies have over 99% specificity for gluten-sensitive enteropathy. FImmunoglobulin A, Qn, Serum55  L87-352 (mg/dL) Ft-Transglutaminase (tTG) IgG183  H0-5 (U/mL) - Negative 0 - 5 - Weak Positive 6 - 9 - Positive >9

      Constant low back, abdominal and pelvic pain!

      By Aussienae · Posted

      Mine is definitely triggered by inflammation and stress! I do also have arthritis in my spine, but the pain is more in my pelvic area. Im sure i have other food intolerances or other autoimmune isues but the more I focus on it and see doctor after doctor, it just gets worse.  Best thing is get of Gluten! (I also avoid lactose). Try to limit stress and anything that causes inflammation in your body.

      Constant low back, abdominal and pelvic pain!

      By ButWhatCanIEat · Posted

      Good morning,   I got an email about replies to this post. Some of my doctors had blamed a slipped disc for the pain I had and that contributes, but after meeting with a gastroenterologist AGAIN and trying some lifestyle modifications, I found out I have IBS and can't tolerate corn or excessive fructose to any degree. Cutting out corn AFTER having cut out all gluten containing products was a real pain but I feel much better now!

      Isolated DPG-Iga

      By trents · Posted

      So, I contacted Scott Adams, the author of that article and also the creator/admin of this website, and pointed out to him the need to clarify the information in the paragraph in question. He has now updated the paragraph and it is clear that the DGP-IGA does serve the purpose of circumventing the false negatives that IGA deficiencies can generate in the tTG-IGA antibody test.
