My daughter is 15 and has been having extremely severe pain on the right side up under her rib cage and along her shoulder blade on same side. She has had tons of ultrasounds and xrays and a hida scan to rule out gall bladder. She has also been nauseated and is underweight. Finally, she had an endoscopy done done Oct 4th and tons of bloodwork. The DR visibly saw and I qoute "severe blunting of villi in duodenum and bulb". The actual biopsy came back negative as well as all the other bloodwork EXCEPT DQ2. That was positive. Does she have Celiac or not???? DR says no. I also have thyroid disease and sjogrens disease. With me having two autoimmune diseases, I very well could have an IGA deficiency. Could my daughter also have this deficiency which would make her bloodwork a false-negative? Thanks in advance for your help!!!!
