Hashimoto's disease and gluten, always enemies?

I have Hashimoto,
I try to manage it as much as I can with thyroid replacements, fish oil, selenium + zinc supplements and the paleo diet but I still have some thoughts about the gluten problem. about a month ago I’ve been tested negative for gluten. Blood work showed I had no gluten issues but I am still concerned about whether I would or would not consume it. I read a lot of articles that say we should avoid gluten not matter what because the negative link between Hashimoto’s disease and gluten is real and patients has to stop eating products with gluten immediately if not sooner. I also know that a simple blood test is not always enough to be sure you’re gluten tolerant. Should I do something more to be sure and if I am really negative for gluten, (which is highly likely because a blood test is about 90% accurate) should I still need to avoid gluten? Should people with Hashimoto’s always need to avoid gluten products no matter what? Even if they test negative for it?

Hi Jeff,
one of the approaches I am considering is a 2 months stint of gluten free, and then reintroduce it in small amounts. I reckon that seems doable, unlike a lifelong commitment! I think it is worth trying, because from what I understand, the thyroid replacement doesn't stop the autoimmune disease from progressively damaging your thyroid. Please correct me if I am wrong, new to this!
I agree Judy, I almost feel sorry for poor gluten.
