Why GI makes no sense

Lecturer A: The normal crypt-to-villus ratio in the small bowel is 1:5.  Anything else should make you think celiac disease.

Lecturer B: The crypt-to-villus ratio should be 1:3.  Less is celiac.

Lecturer C: If you see this clinical history and a specimen with a crypt-to-villus of less than 1:4, the patient has celiac sprue.

This GI block is crap.  Literally.
