So you say you use to, does that mean you are currently (as in when you had the blood word done) eating gluten? If you were not, the tests may not be accurate.
I was eating the gluten-free oats for about a year before test. Nothing else though.
(1) From the celiac panel test results only, you do not have Celiac.
(2) when you say..."They did not look for celiac damage during the endoscopy."..did they do a BIOPSY?
(3) because that is the only way to diagnose Celiac, not from just "looking at your stomach"
