I made a post on another thread in the post dx forum & some there were saying they did not know much about dh 7 wouldn't mind learning more as well as wanting to know what the source was for things I stated. Here is my post, copied & pasted. I did not want to hijack the other thread plus this forum is the best place to discuss dh so I post the sources here.
My post from http://www.celiac.com/gluten-free/topic/95135-my-biopsy-word-for-word/page__st__30
I will also add a tidbit of info
