Dear Ethan:

An IgA Tissue Transglutaminase (tTG) Autoantibody Assay, such as our at-home
test known as the cdSCAN, is designed to determine if gluten-reactive
individuals have celiac disease.  After an elimination period (100%
gluten-free), the antibody associated with celiac disease may not be
detectable, thus ANY laboratory's IgA tTG test, as well as an endoscopy,
might report that an individual is negative for celiac disease - when in
fact they actually have it (celiac disease).

If whoever you are thinking of requesting the test for has consumed gluten
and/or gluten-contain grains in recent history, then the IgA tTG antibody
levels should still be ele
vated - as long as they truly have celiac disease.

Also, in case you are thinking about doing a gluten challenge, I would
recommend against it as this is a bit of a clouded area where there really
are no good answers.  Some individuals develop elevated levels of the IgA to
tTG antibodies very quickly after starting a gluten challenge while it might
take others more time to do.

One thing you could do just to make sure, is to be screened for food
intolerance and see if there is a current positive reaction to gluten and/or
gluten-containing grains.  Our foodSCAN 113-food panel not only screens
various gluten-containing grains for IgG-mediated food allergy, but gluten
(gliadin) intolerance as well.  In the event you have been living a
gluten-free lifestyle, but are still experiencing ill-health, you may likely
be suffering from IgG-mediated food allergy to foods other than gluten.

I hope this information is of b
enefit.  Please let me know if our office
may be of any further assistance.

Sincerely,
