This is very similar to me! I had ttg level of 406 and was told <20 was normal. I had a clear endoscopy. I have been gluten free for almost 6months and ttg has reduced to 49. Apparently as I'm off gluten fully it should be 0 by now?
I didn't think I had symptoms, however now being gluten free I can definitely say I had gas pain, pain when hungry,...
