 Food
allergy test v/s Celiac test?
I just had food allergy testing
(FOODstats Elisa test for IgG and
IgE) and have been searching for
information regarding IgG response
to foods. So far all I can find
is that an IgG response does not
prove I have a food allergy.
My reactions were high for the following
foods: wheat, wheat gluten, gliadin,
whole wheat flour, white flour,
spelt, all dairy including milk
yogurt, casein, eggs yolks, egg
whites, bananas, pineapple and I
even tested positive for sugar.
I had a blood test for celiac about
a year ago and it was negative.
Do I take these results with a grain
of salt or could there be some validity
here? My husband has almost identical
allergies although he had several
IgE reactions.
Thanks for your insight!

Whenever
you have multiple food allergies,
this suggests that your gut is leaky:
that is, the junctions between your
intestinal lining cells have been
disrupted. Protein fragments from
wheat, barley and rye, that cannot
be completely digested by your own
enzymes can cause the disruption,
and do not have to go through the
classic celiac disease mechanism
that depends on genetic factors,
antibody generation (anti-tTG or
anti-gliadin antibodies).
Thus, you will test negative to
standard blood tests (which in commercial
labs may only be 45% sensitive)
for celiac disease. You must get
HLA DQ2 and DQ8 testing, and consider
an intestinal biopsy. You may have
NCGS — non-celiac gluten sensitivity.
My advice: get HLA tested, get an
intestinal biopsy, then go on a
gluten-free diet.
Health and happiness,
