Maybe your followup is for the elevated total IgA, and not for celiac. It is strange not to have a numerical result for the tissue transglutaminase. I hope you get answers in the followup with your GP.

Appreciate the info so far guys. So underneath the score I posted before for IGA scoring elevated. It says this in a box below - Tissu transglutaminase IgA lev:  Reference range:  No range Laboratory comment:  Negative  

Thanks so much for the useful information. What do you mean by invasive, expensive procedure that has some medical risks attached to it, what risks? It appears to be like colonoscopy just other end but never had one so curious in case I need one what to expect thanks

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 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.
