AntiGliadin IGA - dairy/casein crossreaction

[mookymomma]

Hey friends - I’ve been reading for awhile and you all are so knowledgeable, especially when it comes to interpreting labs.

quick background:

I was diagnosed with Hashimotos in 2020. At that time, I was already reducing gluten but still enjoyed an occasional beer or pasta.

At that time, my AntiGliadin IGA stool test was 137. After my diagnosis, it went down to 104 after I went strictly gluten-free and DF.

I started drinking oat milk in my morning lattes and it shot up to 435. My functional MD told me about the cross reactivity of oats so I cut that and it went down to 183.

Then I started doing some whole milk lattes and most recently using heavy cream. Now my numbers are back up to 465. I want to scream and cry. I feel like I’ve done this to myself. My doctor isn’t convinced it’s the heavy cream because that shouldn’t have casein where other mills do and could cross react.

I’m getting a blood AntiGliadin IGA test done in the next week and we are going to see if it’s back down since cutting the heavy cream.

Have any of you experienced such a strong cross reaction to whole milk and/or heavy cream??

 

thank you in advance!

Welcome to the forum!

Can I ask where you are getting this stool test done? I know that Dr. Kenneth Fine pioneered this test, so hopefully it's with his lab, but I can say that most of the people who participate in this forum do the blood tests, as they are considered the standard.

Do you have the reference ranges for the tests? We would need to know more about the positive level cut off marker for this test.

Also, could there be other sources of gluten in your diet? It does seem strange that they could be so high, but your doctor is correct that some celiacs do also have a reaction to oats, and I believe it is around 9% of them.

This article explains how dairy can cause increased tTg results.

Cream can contain casein.

0-157 and my numbers were in the 100s and now they’re in the 400s… same as when I had the oat milk. The test is through Diagnostic Solutions Labs… https://www.diagnosticsolutionslab.com

Super interested to see what the blood test says! And no gluten has been in my diet so it’s very strange.

Thanks! What is the difference been a tTg and an AntiGliadin IGA test?

This is an older article, but still valid:

Update: got my bloodwork results for the AntiGliadin IGA and it was a 3. So considered a “negative” result. Super wild! I’m thankful - sad about the heavy cream 😂

Thank you for all the articles and research that was really enlightening!
