I would like to know the correct range for this test. I have found information online that differs from the lab my physician uses. Thank you for any help you may provide.

Welcome to the forum, Marylee!

There is no industry standard range for any of the celiac antibody tests. Each lab uses their own range scale as they use their own formulation when developing the test. All we can suggest is that you supply us with your numerical result and the range (negative vs. positive) used by the lab that analyzed it if you want us to weigh in on the meaning of the results.

Thank you! It’s actually for my mother. Her result was 10.38.

We need more than your mother's score. We need the range used by the lab. Where is the negative vs. positive divide?

For instance:

<7 = negative

>7 = positive

Here is the copy of the test results. While it appears that it’s clearly negative, I question this lab’s scale as most others I have seen state that over 10 is positive.

The units of measure for this test are not absolute. Each lab uses different units for this test so  one has to go by the lab range.

An example of what I mean by different units: Imagine someone is measuring length, and one person says something is three bananas long, and another says the same thing is six oranges long.

"Here is a copy of the results"? The results you speak of are missing from the post. You only have a few minutes to edit any post before that feature is turned off. This is an anti spam measure.

I take it that you feel you may actually have celiac disease even though the one test you have had was negative. Am I correct? What symptoms do you have?

It's a shame they only ran that one antibody test for celiac disease. There are a number of other antibody tests that could have been run and should have. Here is a primer for celiac disease antibody diagnostic tests: https://celiac.org/about-celiac-disease/screening-and-diagnosis/screening/

We often have people on the forum report negative tTG-IGA results but when other tests are run they are positive.

There is also the possibility that you have NCGS (Non Celiac Gluten Sensitivity) for which there is not test available yet. NCGS is 10x more common than celiac disease and shares many of the same symptoms with celiac disease. To arrive at a diagnosis of NCGS, celiac disease must first be ruled out. In both cases, the antidote is the same: elimination of gluten from the diet.

      Yasso frozen yogurt bars - be careful

      Thanks for sharing this! Talk about frustrating! It is complicated enough to try to keep track of which products are safe, but the concept of the same product sold at 2 different stores--one that is certified gluten-free and one that isn't--that is exactly why having celiac disease is still so difficult, and it is so easy to make mistakes!

      UK Visitors: Award Winning Flapjackery in the West Country (and Chichester, West Sussex)

      It's great that this business has celiac disease awareness and uses gluten-free oats! I wish more restaurants would make such simple changes, for example if Asian restaurants switched to using gluten-free soy sauce, many (but not all!) risks would be eliminated for lots of their dishes.

      Frustrated

      It sounds like you’ve been doing everything right—strictly avoiding gluten, managing food allergies, and advocating for yourself—yet you’re still dealing with severe pain, exhaustion, and other debilitating symptoms. The fact that your colonoscopy came back clear after 31 years gluten-free is a testament to your diligence, but it doesn’t erase the very real...

      Chest pain from celiac

      Could you be having acid reflux? I used to get it soooo bad before I was diagnosed, now very rarely. I didnt have stomach upset, aka silent reflux, but pain in chest (thought I was having a heart attack) and food would get stuck from the esophagus irritation. The things here really helped, especially raising head of bed, sip of apple cider vinegar before...

      Canker sores

      Studies have shown that individuals with canker sores tend to have lower levels of vitamin D in their blood compared to those without the condition. This suggests that vitamin D deficiency could be a risk factor for developing canker sores. Vitamin D deficiency is very common in Celiac Disease.

      It sounds like you’ve been doing everything right—strictly avoiding gluten, managing food allergies, and advocating for yourself—yet you’re still dealing with severe pain, exhaustion, and other debilitating symptoms. The fact that your colonoscopy came back clear after 31 years gluten-free is a testament to your diligence, but it doesn’t erase the very real struggles you’re facing daily. It’s concerning that previous doctors dismissed your celiac diagnosis, and now you’re left fighting for validation while dealing with unexplained symptoms like eye pressure, skin issues, and relentless pain. Menopause and long COVID may be complicating things further, making it even harder to pinpoint the root cause. Are you sure your diet is 100% gluten-free? Do you eat in restaurants...if so, this can be a source of contamination. Trace amounts of gluten over time could explain your symptoms. Many people with celiac disease have additional food intolerance issues which could be temporary. To figure this out you may need to keep a food diary and do an elimination diet over a few months. Some common food intolerance issues are dairy/casein, eggs, corn, oats, and soy. The good news is that after your gut heals (for most people who are 100% gluten-free this will take several months to two years) you may be able to slowly add some these items back into your diet after the damaged villi heal.

The things here really helped, especially raising head of bed, sip of apple cider vinegar before meals with protein, heel thumping, and until it healed, taking DGL after meals to coat...do NOT take antacids https://drjockers.com/acid-reflux/ DGL https://www.amazon.com/Integrative-Therapeutics-Rhizinate-Deglycyrrhizinated-Licorice/dp/B001WUC406/
