Hi Kay,
Below I have placed a couple of links to the Mayo Clinic website.
If the first link does not work due to it breaking into two lines during
transmission, the second short one should work.
Also the main text from their website.
My understanding as a lay person is that the blood test for antibodies will
come out negative when a person has been glutenfree as there is no reason
for the body to develop antibodies anymore.
Also a biopsy will probably not show any damage to the villi as these will,
in the meantime, have healed.
There is also a test to look for the genetic markers for celiac disease, but
this test does not confirm that a person has celiac disease. What this test
confirms is, if the markers aren't present, that the person tested does not
have celiac disease.
To get a meaningful result for the anti gliadin and biopsy tests, the person
would have to ingest a certain amount of gluten again over several weeks to
develop antibodies and again do damage to the villies.[pk] From memory I
think it is at least two slices of white bread per day.
The majority of people will not want to go through the ordeal again after
having experienced an improvement after going onto a gluten free diet, as
they feel so much better.
Below not the web links and the excert from the Mayo Clinic website.

Screening and diagnosis
People with celiac disease carry higher than normal levels of certain
antibodies (anti-gliadin, anti-endomysium and anti-tissue transglutaminase).
Antibodies are specialized proteins that are part of your immune system and
work to eliminate foreign substances in your body. In people with celiac
disease, their immune systems may be recognizing gluten as a foreign
substance and producing elevated levels of antibodies to get rid of it.
A blood test can detect high levels of these antibodies and is used to
initially detect people who are most likely to have the disease and who may
need further testing. To confirm the diagnosis, your doctor may need to
microscopically examine a small portion of intestinal tissue to check for
damage to the villi. To do this, your doctor inserts a thin, flexible tube
(endoscope) through your mouth, esophagus and stomach into your small
intestine and takes a sample of intestinal tissue.
A trial of a gluten-free diet also can confirm a diagnosis,
but it's important that you not start such a diet <---------
before seeking a medical evaluation. Doing so may change the results of
blood tests and biopsies so that they appear to be normal.

An acquaintance who has been following a gluten-free diet for 8 months
asked me if a blood test would confirm if she is or is not celiac. Her
doctor
was very skeptical that she was celiac as an endoscopy did not confirm such.
However she was experiencing such pain and was so exhausted that she
voluntarily went gluten free. Thanks for your assistance. I will
summarize.
