Could Someone Explain Enterolab Test?

I understand that it tests for antibodies in the stool, but what does it really tell you? I have had neg blood work, neg biopsy, but a positive dietary response. And how reliable are they, how accurate? Do they mean more than a biopsy/blood work?

Will the Enterloab test just tell me if I am truly sensitive to gluten? Thanks

Maybe, but you already know that. I have never seen any independent studies as to the accuracy of Enterolab's testing.

As you said Enterolab looks for antibodies to gluten and if desired, casien, eggs and soy. If your body is producing antibodies to a substance that means it is trying to protect you from that substance. Someone who is not reactive will not produce antibodies.

Enterolab does not diagnose celiac, they simply tell you if your body is reacting to gluten.

Opinions on Enterolab vary here. I did not use them for diagnosis but did use them years later to look for a reaction to soy and casien and also to check what genes I have.

In terms of Celiac, no.

Has anyone had a neg biopsy w/ neg blood work? but positive Enterolab results?

I would just like some confirmation that I have celiac, just for my own personal gratification. Does anyone have any suggestions? My next step is going for genetic testing.

There are many people who have had positive E. results, but neg blood/biopsy.

Enterolab does not diagnose Celiac.

You may not have Celiac, and instead, a non-Celiac gluten intolerance.

Would non-Celiac gluten intolerance include symptoms of depression, steatorrhea, insomnia, and fatigue? I would assume that bloating and loose stools are common in both.

And according to wikipedia, non-Celiac gluten intolerance does not exist and not according to Web-MD either. Apparently it's not an official diagnosis, but maybe more of an allergy?

There are many different presentations to gluten induced illness. For some gluten intolerance is simply celiac that has not yet or even will not ever have serious enough gut effects to fit the classic celiac diagnosis.

DH is an example, not all folks with DH develop villi damage but they are still recognized as celiac. For some of us gluten's impact on the brain with symptoms like depression and anxiety and brain fog can exist for years before gut impact is felt. Many would call those folks gluten intolerant rather than celiac. For some the definition of gluten intolerance is simply that the villi are not totally destroyed or the biopsy was negative but the person still responds well to the diet.

The study of celiac and it's many presentations in the US is a bit centered on only the gut stuff. Many don't realize it can impact other organs. What many here call gluten intolerance really needs to be treated the same as biopsy proven celiac by the total exclusion of gluten.

      Test interpretations

      Based on those results alone, it’s not possible to say you have celiac disease. The test that is usually most specific for celiac, tTG-IgA, is negative in your results, and the endomysial antibody (EMA) is also negative, which generally argues against active celiac disease. However, your deamidated gliadin IgA is elevated, and your total IgA level is also h...

      Test interpretations

      Since you compromised the validity of the antibody testing by experimenting with gluten withdrawal ahead of the testing, you are faced with two options: 1. Reintroduce significant amounts of gluten into your diet for a period of weeks, i.e., undertake a "gluten challenge". The most recent guidelines are the daily consumption of at least 10g of gluten...

      Need advice for some relief!

      Hi Kayla Huge sympathies. I was diagnosed in December, after 8 months of the most awful rash, literally top to toe. Mine is a work in progress. Im on just 50mg dapsone at the moment but probably need an increased dose to properly put the lid on it. As you have been now glutened, I wondered whether it might be worth asking for a skin biopsy to finally...

      Test interpretations

      Based on those results alone, it’s not possible to say you have celiac disease. The test that is usually most specific for celiac, tTG-IgA, is negative in your results, and the endomysial antibody (EMA) is also negative, which generally argues against active celiac disease. However, your deamidated gliadin IgA is elevated, and your total IgA level is also high, which can sometimes affect how the other antibody tests behave. Another important factor is that you were reducing gluten before the test, which can lower antibody levels and make the results less reliable. Because of that, many doctors recommend a gluten challenge (eating gluten regularly for several weeks) before repeating blood tests or considering an endoscopy if symptoms and labs raise concern. It would be best to review these results with a gastroenterologist, who can interpret them in context and decide whether further testing is needed.

      Since you compromised the validity of the antibody testing by experimenting with gluten withdrawal ahead of the testing, you are faced with two options: 1. Reintroduce significant amounts of gluten into your diet for a period of weeks, i.e., undertake a "gluten challenge". The most recent guidelines are the daily consumption of at least 10g of gluten (about the amount found in 4-6 slices of wheat-based bread) for at least two weeks leading up to the day of testing. Note: I would certainly give it more than two weeks to be sure. 2. Be willing to live with the ambiguity of not knowing whether gluten causes you problems because you have celiac disease or NCGS (Non Celiac Gluten Sensitivity). There is no test for NCGS. Celiac disease must first be ruled out and we have tests for it. Celiac disease has an autoimmune base. NCGS does not. GI symptoms overlap. In the early stages of celiac disease, other body systems may not be showing stress or damage so, symptomatically, it would be difficult to distinguish between celiac disease and NCGS. Both conditions require elimination of gluten from the diet for symptom relief. Some experts feel that NCGS can be a precursor to celiac disease.

      I had been eating reduced gluten until about 3 days before the test. I did realize that wasn’t ideal, but it was experimental to see if gluten was actually bothering me. One slip up with soy sauce and it was quite clear to me that it was, lol.

      Possibly. Your total IGA (Immunoglobulin A, Qn, Serum) is actually high so you are not IGA deficient. In the absence of IGA deficiency, the most reliable celiac antibody test would be the t-Transglutaminase (tTG) IgA for which your score is within normal range. There are other things besides celiac disease that might cause an elevated DGP-IGA (Deamidated Gliadin Abs, lgA) for which you do have a positive score. It might also be of concern that your total IGA is elevated as that can indicate some other health problems, some of which are serious.  Had you been practicing a gluten free or a reduced gluten free diet prior to the blood draw? Talk to your physician about these things. I would also seek an endoscopy/biopsy of the small bowel to check for damage to the villous lining, which is the gold standard diagnostic test for celiac disease.
