For people eating a gluten-free diet who are unable to perform an oral gluten challenge, an alternative to identify a possible celiac disease is an in vitro gliadin challenge of small bowel biopsies, but this test is available only at selected specialized tertiary-care centers. [5]
Diagnosis is typically made by a combination of blood antibody tests and intestinal biopsies, helped by specific genetic testing. [10] Making the diagnosis is not always straightforward. [22] About 10% of the time, the autoantibodies in the blood are negative, [23] [24] and many people have only minor intestinal changes with normal villi. [25]
Most attention to anti-transglutaminase antibodies is given with respect to celiac disease. A recent study of children published in 2007 demonstrated that the level of ATA in correlates with the scalar Marsh score for the disease in the same patient. [9] High levels of ATA are found in almost all instances of celiac disease. [10]

Anti-gliadin antibodies are produced in response to gliadin, a prolamin found in wheat.In bread wheat it is encoded by three different alleles, AA, BB, and DD.These alleles can produce slightly different gliadins, which can cause the body to produce different antibodies.
Menounos said she was tested for celiac disease but got no answers. ... Menounos got stool and blood tests, all of which had “unremarkable” results. "They said everything's fine," but the ...
Tests for the antibodies in the blood can be used clinically to help screen for celiac disease, IgA blood tests for both tTG and endomysial tTG can be effective ways to determine whether someone has Celiac disease, especially in more severe cases, although for more common, mild forms of Celiac, these tests are less effective.
Celiac disease affects ~1% of the population in most parts of the world. [3] Ninety to one hundred percent of patients with coeliac disease have inherited genes at the HLA-DQ locus that encode HLA-DQ2 and/or HLA-DQ8 serotype proteins. [12] About 2–3% of individuals who inherit these HLA-DQ2 and/or HLA-DQ8 serotypes develop coeliac disease. [10]
