I must disagree with the notion that celiac disease is like any other
allergy.  It certainly resembles allergy in that avoidance is the
treatment, however the damage that is caused both to the intestine and
subsequent effects on other parts of the body due to the malabsorbtion
are not like allergies.

Further, depending on the lack of symptoms as a sign of wellness may not
be enough in following up celiac disease especiallt that is diagnosed in
adulthood.  It is well recognised that significant damage can be present
in the intestine in the absence of symptoms especially in family members
of patients with celiac disease.

I define a satisfactory response to the GFD as signs of healing of the
intestine.  one sign may be loss of symptoms, but in many it is not
enough.

Celiac disease also needs to be differentiated from simple maldigestion
of wheat, which is very common and has none of the longterm implications
of CD.  in the situation of simple wheat intolerance ( without evidence
for CD) all one needs to do is to avoid wheat to the extent that symtpoms
are avoided.  this is not the same as the complete lifelong avoidance of
gluten required in CD.
