Are These The Right Tests?

These are tests that are still pending:

Gliadin IgA, Gliadin IgG, Transglutamin IgA, Transglutamin IgG, Endomysial Ab IgA, Quantitative IgA

Of course my H. Pylori test came back negative. If I'm above or below any of these ranges, does that prove or disprove celiac?

Thanks!

Those are the right tests for Celiac.

The total/quantitative test is not a Celiac test, per se - instead, it looks to see if you are IgA deficient. If you are, then the IgA based tests won't be accurate. If you are IgA deficient, you could have Celiac, but test negative for it.

No one test is perfect for Celiac, but the tTG & EMA tests are newer and generally more sensitive/specific.

When you have these blood tests are they looking for low or high numbers? Here are the numbers I had;

IgA 84 (lab range 81-463)

IgG 1136 (lab range 694-1618)

IgM 54 (lab range 48-271)

My doctor says I do not have celiac disease. I have been having a tough fall and winter with fatigue, brain fog, joint pain, etc. My thyroid TSH was slightly elevated at first but has since come down to a normal range. I have had a lot of blood work. The only other one that came up abnormal was the ferritin level that was very low. Any help of these blood tests would be appreciated.

Hi ticketlady,

The tests that you posted are not for Celiac. Doctors often run the "IgA" test in conjunction with the celiac tests, but the total IgA is not a Celiac test, itself. How did you doctor determine you don't have Celiac? Did you have any tests run that say things like anti gliadin (AGA), tissue transglutaminase (tTG) or endomysial (EMA)?

I thought those were the tests I was looking for. She also did Tissue Transglutaminase Antibody (IgA), and Endomysial Antibody Screen both of which she said were normal but did not give me numbers. She was the one who suggested I could have celiac and I want to make sure the proper tests were done and right now from what I read here I don't think I've had the correct tests. I know she has screened me for Lyme, HepC, inflamation, Rheumatoid Arthritis and othe things that I can't recall at the moment.

The tTG IgA and EMA screen are the two most sensitive/specific tests for Celiac. It doesn't mean you don't have it since you tested negative, but the chances are lower given negatives on both (which is why she doesn't think you have Celiac).

      Draft gluten-free ciders… can they be trusted ?

      I'd go with a vodka tonic, but that's just me😉

      Draft gluten-free ciders… can they be trusted ?

      By Rejoicephd · Posted

      That and my nutritionist also said that drinking cider is one of the worst drink choices for me, given that I have candida overgrowth.  She said the combination of the alcohol and sugar would be very likely to worsen my candida problem.  She suggested that if I drink, I go for clear vodka, either neat or with a splash of cranberry.   So in summary, I am giving ciders a rest.  Whether it's a gluten risk or sugars and yeast overgrowth, its just not worth it.

      Tea Bags and Gluten

      By Scott Adams · Posted

      While plain, pure tea leaves (black, green, or white) are naturally gluten-free, the issue often lies not with the tea itself but with other ingredients or processing. Many flavored teas use barley malt or other gluten-containing grains as a flavoring agent, which would be clearly listed on the ingredient label. Cross-contamination is another possibility, either in the facility where the tea is processed or, surprisingly, from the tea bag material itself—some tea bags are sealed with a wheat-based glue. Furthermore, it's important to consider that your reaction could be to other substances in tea, such as high levels of tannins, which can be hard on the stomach, or to natural histamines or other compounds that can cause a non-celiac immune response. The best way to investigate is to carefully read labels for hidden ingredients, try switching to a certified gluten-free tea brand that uses whole leaf or pyramid-style bags, and see if the reaction persists.

      Inconclusive results

      By Scott Adams · Posted

      This is a challenging and confusing situation. The combination of a positive EMA—which is a highly specific marker rarely yielding false positives—alongside strongly elevated TTG on two separate occasions, years apart, is profoundly suggestive of celiac disease, even in the absence of biopsy damage. This pattern strongly aligns with what is known as "potential celiac disease," where the immune system is clearly activated, but intestinal damage has not yet become visible under the microscope. Your concern about the long-term risk of continued gluten consumption is valid, especially given your family's experience with the consequences of delayed diagnosis. Since your daughter is now at an age where her buy-in is essential for a gluten-free lifestyle, obtaining a definitive answer is crucial for her long-term adherence and health. Given that she is asymptomatic yet serologically positive, a third biopsy now, after a proper 12-week challenge, offers the best chance to capture any microscopic damage that may have developed, providing the concrete evidence needed to justify the dietary change. This isn't about wanting her to have celiac; it's about wanting to prevent the insidious damage that can occur while waiting for symptoms to appear, and ultimately giving her the unambiguous "why" she needs to accept and commit to the necessary treatment. This article might be helpful. It breaks down each type of test, and what a positive results means in terms of the probability that you might have celiac disease. One test that always needs to be done is the IgA Levels/Deficiency Test (often called "Total IGA") because some people are naturally IGA deficient, and if this is the case, then certain blood tests for celiac disease might be false-negative, and other types of tests need to be done to make an accurate diagnosis. The article includes the "Mayo Clinic Protocol," which is the best overall protocol for results to be ~98% accurate.
