Clinic significance
A marker for celiac disease - assayed in parallel to the anti-endomysium, anti-transglutaminase and anti-reticulin antibody tests. Useful for deciding whether or not a jejunal biopsy is warranted. The IgG assay is more sensitive but less specific. After commencement of a gluten-free diet, the IgA antibodies disappear within 3 months and the IgG antibodies within 6 months but both reappear if the diet is not maintained.
