There are various test methods employed for establishing the diagnosis of CD.
 These include:

Histopathology on gut biopsy
Serum antibody tests (EMA, ARA and AGA)
Absorption test (Xylox absorbtion test)

Of these, Xylose absorption test is least specific and it measures the
physiological damage to the gut.  In light of newer findings, this test is
used less and less.  The most common test(s) that are employed these days for
screening for CD are the antibody tests.  Additional information on these
tests can be obtained from:
