Thank you very much. This was actually very helpful. I have some old medical results from years ago, that I don't (didn't understand). I looked through them to see if IgA was there, and it is. I didn't know what that was until now.

My IgA test was negative. The false negative rate for that test is 10%, so I have a small chance of actually having coeliac, but I probably don't.

Anyway, I definitely might end up getting another biopsy done to check for coeliac. (I had one done, but it was too high up, above the duodenum, to say anything about coeliac.)
