Rachel in NC replied to RunnerNYC's topic in Celiac Disease - Pre-Diagnosis, Testing & SymptomsHi, I was wondering the same exact thing. My situation is a little different. I had a biopsy first, went on a gluten free diet and now my doctor wants me to eat gluten for 10 days and then have the blood test. He said it would throw off the results if I had no gluten within the last 2+ weeks. Has anyone else experienced this? Also how conclusive is the biopsy compared to the blood test? Thanks alot for everyones help.. I can notice a difference just today eating gluten. I feel bloated and very tired!
