So I got my gluten sensitivity stool test results back today:

 

Fecal Anti-gliadin IgA      36 Units   (Normal Range is less than 10 Units)

 

According to them, this means I need to avoid gluten. I'm not really surprised at the results. But they don't distinguish between gluten sensitivity and full-blown Celiac disease. Do stool test numbers correspond to blood test numbers?

 

I guess my next step is to have my GI doctor redo the Celiac blood test. I had a blood test done in November (and it was negative), but it wasn't valid because I'd been off gluten for several weeks. Now I've been eating gluten again for five weeks. I think I need to go eight weeks for a valid blood test, right? My birthday is in about three weeks, so I guess I'll eat a whole bunch of birthday cake and go out with a bang. LOL

"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."

"We only embrace tests that have endured rigorous scientific evaluations. So far, these tests have received no evidence-based support.

Enterolab has never successfully published anything on the accuracy of stool tests (nor have any other stool test manufacturers, to our knowledge) making it difficult to confirm the research results. Because of this, we must make our decisions based on what has been published; Harvard, UCSD, and the American College of Gastroenterology all agree that stool tests are simply not sensitive or specific enough methods in screening for celiac disease.

We can say therefore with confidence that the test currently being used by these labs is not good enough. In fact, while it is true that about 40% of people with proven gluten sensitivity have elevated AGA-IgG, it is also true that about 15-25% of the healthy individuals who have absolutely nothing wrong also have elevated AGA-IgG. Hence, about 60% of gluten sensitive people do not have elevated AGA-IgG (making the test not sensitive enough); and about 20% of normal, non-gluten sensitive people have elevated AGA-IgG for no apparent reason (making the test not specific enough)."

How did your body respond to being gluten free and how has it responded to the challenge? IMHO that is the most important thing to which you should be paying attention. While it can be helpful to get a firm diagnosis if the diet is helping you should stick with it after all your testing is finished no matter what the results.

Well, I was off gluten for seven weeks. Since I've been back on gluten, I've noticed that I'm much more tired, I use the bathroom more, and the vision in my left eye is worse. So I do plan to avoid gluten after the next blood test, but I still hope that I don't have Celiac, of course, so I don't have to freak out if I eat something with a little bit of soy sauce in it (for example). Of course, being gluten-free could really mess up dreams of moving abroad in a few years. :-(

There are celiacs all over the world; don't give up on your dreams! 

 

Enterolab offers a TTG test that may be a bit more informative as it looks at autoimmune activity.  Read this celiac.com blog post:

https://www.celiac.com/gluten-free/blog/856/entry-1546-enterolab-a-scientists-viewpoint/

 

If I remember correctly, Dr Fine did submit a paper for publication a few years ago and I don't think it was ever published. 

 

It is possible to have all the blood work be negative, the tests just aren't perfect. 

 

My spouse has never had any positive blood work. He did have a positive TTG test from enterolab and he did work with a GI doc to be sure it wasn't something else. He did a formal gluten challenge and became very ill over the 3 months. The doc told me, right after the endoscopy, that he was sure my husband had celiac.  The biopsy did come back negative, but at the follow up visit, the Gi doc said, based on what he saw, that he supported my husband's decision to not eat gluten. So, no formal diagnosis and can't use blood work to track his progress with the diet. 

 

However, he's had excellent response to the diet, the anemia is gone, etc. He also eliminated casein, so we confounded our variables. He did have multiple positive blood tests for casein. 

 

He retests with Enterolab with the TTG test annually and so far (5 years) has never gotten into the normal range, although his #'s have dropped.

The blog post you link to explains why Enterolabs are not a good choice for tests.

      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.
