Have you seen Cyrex food sensitivity panel antibodies such as gluten or dairy drop after successful treatment of all heavy metals and/or SIBO? Have patients subjectively been able to tolerate more foods after healing their bodies that they previously could not?

Chris Kresser: The answer is yes to both of those questions. We’ve seen objective markers change after successful treatment of...

Would it be possible that cross-reactive foods with gliadin could also cause elevated TPO antibodies? Also have you seen TPO antibodies decrease with removal of iodine supplementation?

Chris Kresser: The answers to those questions are yes and yes. I’ve seen both of those things happen and it’s...

I did a Cyrex Array 4 test on a father-daughter, both have celiac disease. Dad has antibodies to gluten-containing grains and milk chocolate. Can you safely say that he’s not a hundred percent compliant with the gluten-free diet, which is the reason for antibodies to the gluten-containing grains?

Dr. Amy Nett: A hundred percent? Absolutely not. No. There’s very little you can say with a hundred percent certainty....

Since he’s making antibodies to milk chocolate, is it okay to continue having other dairy like milk and cheese or best to avoid all dairy?

Dr. Amy Nett: Well, yeah, like we’ve said, milk chocolate, this marker really doesn’t make sense to me because it’s...

With regards to the daughter, she is making antibodies to most of the dairy proteins. Do you advise removing all dairy forever or would it be okay to consider reintroducing?

Dr. Amy Nett: Well, I think if you can find—I would do, as with other patients, do the gut testing....

Karen did a Cyrex Array 3 on a 12-year-old patient. She had IgG antibodies to wheat and wheat germ agglutinin. The family eats a fairly conventional diet and the mother does not want to make her diet unnecessarily restrictive. Should she avoid wheat in addition to rye and barley or only wheat?

Dr. Amy Nett: Okay. I don’t know that it would be unnecessarily restrictive to remove wheat based on those markers....

I did the Cyrex Array 4 test on a patient with celiac disease. Very high antibodies to dairy. In your experience, do these kinds of patients need to avoid dairy forever? Or would you reintroduce after 60 days?

Dr. Amy Nett: So to me, the reintroduction would not be after 60 days. If you wanted to reevaluate dairy,...

I had a patient come in with Genova food sensitivity IgG test results. Can I get any reliable information from it?

Chris Kresser: For most of the other IgG and IgA food intolerance testing, I tell patients it can be a...

Patient has HLA-DQ8 heterozygous. It isn’t showing any symptoms on eating gluten or cross reactive foods. Ran Cyrex Array 3 and came back clean as a whistle. Sharing with him that gluten takes longer to digest and can lead to inflammation. Thoughts on how to convince this TBI patient to switch over when labs aren’t showing issues.

Chris Kresser: I think your case isn’t as strong, to be honest. I don’t think gluten is an issue for...

Regarding the prep diet for the Genova organics test, I had a question. I’m wondering why there is no mention of eating enough protein a day before to test something like indican or avoiding or limiting polyphenol-rich foods that can impact the bacterial markers?

Chris Kresser: We’ve had really not very different results from those recommendations. We did actually have people eat significant amount...
