Dear Dianne in B.C. Canada,
 
I believe that most (knowledgeable) GI doctors will (should)
recommend the normal 2 or 3 blood tests to screen for
CD in any patient with a suggestive family history and
certainly any patients with symptoms.  These tests are
well known and fairly reliable.  If these tests are
positive, the patient MUST be biopsied (small intestine)
normally with an upper endoscopy, to confirm the CD
diagnosis.
 
It is harmful to a CD person to have even small amounts of
gluten in their diets.  The damage could be cumulative.
 
Please follow through with this all the way and then, if
positive, follow a strict gluten free diet.
 
Good luck
