I would agree. The tests do not indicate you have celiac disease. So, if you are convinced that when you eliminate gluten from your diet your symptoms improve, I would conclude you have NCGS.

My old results are: The Tissue Transglutaminase IgA antibody - 0.5 U/ml (for the lab I did the tests 0.0 - 3.0 is normal) The Tissue Transglutaminase IgG antibody - 6.6 U/ml (for the lab I did the tests 0.0 - 3.0 is normal) Immunoglobulin A - 1.91 g/l (for the lab I did the tests 0.7 to 4 g/l is normal) IgA Endomysial antibody (EMA) - < 1:10 titer (for the lab I did the tests < 1:10 titer is normal) IgG Endomysial antibody (EMA) - < 1:10 titer (for the lab I did the tests < 1:10 titer is normal) Deamidated gliadin peptide IgA - 0.3 U/ml (for the lab I did the tests 0.0 - 6.0 is normal) Deamidated gliadin peptide IgG - 46.1 U/ml (for the lab I did the tests 0.0 - 6.0 is normal)   Then I didn't eat gluten for six months and after I started a gluten challenge. Before the challenge I did some tests as RMJ had suggested to do. My results: The Tissue Transglutaminase IgG antibody - 0.5 U/ml (for the lab I did the tests < 20 U/ml is normal)) Deamidated gliadin peptide IgG - 28 U/ml (for the lab I did the tests < 20 U/ml is normal)   As trents suggested I ate 6 slices of wheat bread before the tests during the challenge. My results: The Tissue Transglutaminase IgA antibody - 2.0 U/ml (for the lab I did the tests < 20 U/ml is normal) The Tissue Transglutaminase IgG antibody - 2.0 U/ml (for the lab I did the tests < 20 U/ml is normal) Immunoglobulin A - 1.31 g/l (for the lab I did the tests 0.7 to 4 g/l is normal) Deamidated gliadin peptide IgA - 2.0 U/ml (for the lab I did the tests < 20 U/ml is normal) Deamidated gliadin peptide IgG - 2.13 U/ml (for the lab I did the tests < 20 U/ml is normal)   As I can understand I don't have celiac disease.

So it sounds like Global Foods has adopted the FDA standard for "gluten free" advertising.

Agreed, I am disappointed in the recent GFCO findings as well and definitely don't hold them in as high of a regard as I used to. I did find on the Global Foods website after posting that their required ppm limit is 20ppm, which isn't as low as I had hoped. I'll email and report back. Thx.

Never heard of them. They give an email address so if I were you I would contact them and ask those questions. It would be wonderful if they had tighter requirements than GFCO in the sense of more frequent batch testing and even random testing. Recent news articles on this forum from back in this summer have revealed that GFCO is letting us down.
