I have reacted badly to nutiva shelled hemp seeds. I'm not aware I'm reactive to hemp, so maybe their seeds are contaminated. I notice they explicitly do not state their hemp seeds are gluten free on their web site, though they state their chia seeds and coconut products are gluten free. I also notice in the email above they do not state their hemp seeds are tested. I recommend you try other brands or products. Please let me know if you have other results!
The answer to your main question is No, you don't have to have a biopsy for diagnosis, but it'll probably be requested by your gastroenterologist. Most doctors will refer you to a gastroenterologist. Look for an internist or other doctor who specializes in digestive disorders and nutrition issues. My biopsy was negative after 30 days of eating guten. My digestive issues got worse every day I was eating wheat, and it took 2 months to feel better after I stopped. While the gastroenterologist didn't diagnose me celiac due to the negative biopsy, another doctor did so following a diagnosis of autoimmune (Hashimoto's) thyroiditis, B12 deficiency following the 30 days eating gluten, and positive DNA tests for celiac and gluten sensitivity (Enterolab). I've also heard of people having negative DNA tests and positive biopsy. The more information you can provide, the better. Keep meeting new doctors with different clinical specialties. Look for autoimmunity, which is common with celiac. If you know eating gluten will be horrible, have some testing done in the other areas.
