Diane,

I just got diagnosed w/ sprue about 6 months ago, I had the same symptoms
as you, minus the anemia.  The only reason I was tested for it is that my
mom has sprue.  I was given the blood tests and they all came out
negative, but since we were suspicious, my doctor referred me to a
Gastroenterologist anyway.  He did a small intestine biopsy, which came
out positive.  The point is, blood tests may not show anything, and the
only way to be sure is to actually get the biopsy done.

Good luck!

Eric
