Dr. Ford Said It Best: Dgp Vs. Aga

little bit of a rant...

 

ok so as I continue to research everything, I now have a good grasp on the difference between DGP and AGA and what they do and measure.  One of the first things I read was this page by Dr. Rodney Ford:

Open Original Shared Link

 

he lays things out in easy to understand terms that I truly do appreciate :)

 

I have to use LabCorp for my insurance, and I found this comical, but also sad at what they have listed on this page under Additional Information:

Open Original Shared Link

 

 

"A negative IgA result in an untreated patient does not rule out gluten-sensitive enteropathies, especially when associated with IgG gliadin antibodies. This can be explained by selective IgA deficiency, a relatively frequent finding in celiac disease. False-positives are possible as other gastrointestinal disorders are known to induce circulating antigliadin antibody, mainly Crohn's disease, food protein intolerance, and postinfection malabsorption."

 

I HATE that they use terms AGA and DGP interchangeably.  If I was reading this, and was completely new to everything, I would think that means maybe I have Crohn's, protein intolerance, and/or postinfection malabsorption, but they are referencing AGA on this page for the DGP testing :blink:  No wonder people get confused.  Right now the only thing DGP shows is celiac, and until that is proved otherwise, that's what it is.  I've asked my GI, asked others on the board, and currently that's what DGP tests show.  I can't wait until more studies are done in regards to DGP!  Yes, I fixate on the DGP test :) They should have named the DGP test something COMPLETELY different than the AGA test.  Oh modern medicine is a love-hate relationship with me :P

 

done rant.  thanks for listening  :)

I can't get it to link correctly, so Plan B :)

 

if you're interested to see what I'm griping about when you get to the search box put in

 

Gliadin Antibody Profile, IgA, IgG, EIA

 

Edit: If I completely sign-out of my account and close my browser, and then open the browser again as a guest, the first time I click on it the link it brings me to a search page.  If I go from the Labcorp search page and use the back arrow to my original post, and then click the link again, it brings me to the actual testing page...strange...

Not sure what exactly you want us to see but ...could you copy it and paste it here?  I'll take your word that its what the lab says as I'm too lazy to look it up.  I think I had a Celiac panel done by Lab Corp before.

geez this is turning out to be quite a process :P it bothers me when I can't figure something out, and I don't know why it isn't linking...

 

Ok anyway onto the point:

 

This is a screening test of only Deamidated Gliadin Antibodies, but in the "additional information" for this screen it states the following:

A negative IgA result in an untreated patient does not rule out gluten-sensitive enteropathies, especially when associated with IgG gliadin antibodies. This can be explained by selective IgA deficiency, a relatively frequent finding in celiac disease. False-positives are possible as other gastrointestinal disorders are known to induce circulating antigliadin antibody, mainly Crohn's disease, food protein intolerance, and postinfection malabsorption.

 

Why are they discussing antigliadin antibodies if this is a DGP test, and in addition, all of their references in compiling this "additional information" section are from the early '90s :wacko:

 

I'm making a big fuss, and I didn't even get this particular test ordered :P I had the DGP tests done as part of their Celiac Disease Comprehsive Panel.

      Tea Bags and Gluten

      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.

      Medication

      By Scott Adams · Posted

      Welcome to the community! Generally, for a gluten challenge before celiac disease blood tests, Tylenol (acetaminophen) is considered safe and should not interfere with your antibody results. The medications you typically need to avoid are those like ibuprofen (Advil, Motrin) or naproxen (Aleve) that can cause intestinal irritation, which could potentially complicate the interpretation of an endoscopy if you were to have one. However, it is absolutely crucial that you confirm this with either your gastroenterologist or your surgeon before your procedure. They know the specifics of your case and can give you the definitive green light, ensuring your surgery is comfortable and your celiac testing remains accurate. Best of luck with your surgery tomorrow

      Taking Probiotics but Still Getting Sick After Gluten – Advice?

      By Xravith · Posted

      Thank you for the advice. I’ve actually never checked for nutritional deficiencies, but for as long as I can remember, I’ve always taken vitamin and mineral supplements — otherwise my symptoms get worse. This week I stopped eating gluten to confirm whether my symptoms are really caused by it. Starting next week, I’ll reintroduce gluten — it’s sad to go back to how I was before — but at least I’ll be able to take the necessary tests properly. I think the diagnostic process will be long, but at least I’m happy that I finally decided to address this doubt I’ve had for years.
