The other thing to understand is that if the blood antibody testing is negative, it is most likely that the endoscopy/biopsy will also be negative. The blood tests are checking for antibodies from the damage caused by celiac inflammation. The biopsy is checking optically for the same damage. If there are no antibodies being produced then there is no damage... -

Elimination diet think I may be Gluten tolerant next steps to get tested? Questions
Technically speaking, the blood test is not required before the endoscopy/biopsy but you may have a hard time finding a physician willing to do an endoscopy/biopsy without it having been preceded by positive celiac blood antibody test scores. Positive antibody test scores provide the justification for going forward with an invasive, expensive procedure that... -

@LeeRoy83, what RMJ is referring to is the test for IGA deficiency, often called "total IGA". It is not a celiac diagnostic test per se. However, if this test score is low (i.e., you are IGA deficient), the celiac IGA test scores cannot be trusted as they will be artificially low which may include false negatives. Possibly, RMJ is correct. But I'm looking... -

In general, and I've visited many boutique cheese manufacturing facilities here in Sonoma County, CA, there is no wheat anywhere near them. Dairies generally don't process wheat products, and in cheese making cleanliness is next to godliness--they tend to keep things very clean to the point of sterile so their cheeses won't get contaminated with bacteria... -

Is the blood test required before endoscopy? Can it just go to endoscopy to test. Or would you need to be in gluten diet either way. Can you also be gluten sensitive but not sensitive to cross contamination? Thanks

The blood tests are checking for antibodies from the damage caused by celiac inflammation. The biopsy is checking optically for the same damage. If there are no antibodies being produced then there is no damage happening. In either case, a gluten challenge would be necessary. -
Technically speaking, the blood test is not required before the endoscopy/biopsy but you may have a hard time finding a physician willing to do an endoscopy/biopsy without it having been preceded by positive celiac blood antibody test scores. Positive antibody test scores provide the justification for going forward with an invasive, expensive procedure that has some medical risks attached to it, especially since the gluten free diet is the antidote for both celiac disease and NCGS. We sometimes do see endoscopies/biopsies to check for celiac disease without positive biopsies but only when there is obvious failure to thrive for no other apparent reason and the patient has deteriorated to the point where it has become life threatening. We also see it sometimes done incidentally when checking for other GI-related medical problems. In your case, there is no obvious reason to suspect celiac disease as opposed to NCGS as all your general lab work values are fine. You just have some GI distress associated with gluten. There is no evidence at this point to suggest that you are suffering from malabsorption. NCGS is 10x more common than celiac disease.

However, if this test score is low (i.e., you are IGA deficient), the celiac IGA test scores cannot be trusted as they will be artificially low which may include false negatives. Possibly, RMJ is correct. But I'm looking at the list of terminologies employed for the various tests as laid out in this article: For the IGA deficiency test, here is the list: Other Names for the IgA Levels/Deficiency Test: Immunoglobulin A (IgA) Test Total IgA Test Serum IgA Test IgA Serum Levels Test IgA Blood Test IgA Quantitative Test IgA Antibody Test IgA Immunodeficiency Test None of those match very well with the test score you posted which is the "Tissu (Sic) transglutaminase IgA" which lends itself to the acronym, TTG-IGA.
