"Negative biopsies" may be reported in a celiac patient due one of several
reasons.
-- The patient may already have been on a GFD
-- The disease may be somewhat patchy therefore many would advocate doing
3-4 samples from the small intestine.
-- The pathologist may not recognise subtle changes that can be due to
celiac disease.
-- There may be some other process such as peptic ulcer disease that may
occur simultaneously and mask the celiac disease changes.
