Marker of celiac disease associated with gluten-sensitive enteropathy or dermatitis herpetiformis. A positive result indicates the presence of Gliadin IgG antibodies and suggests the possibility of certain gluten sensitive enteropathies such as celiac disease and dermatitis herpetiformis. In treated patients known to express IgA antibodies, gliadin IgA antibody levels represent a better indicator of dietary compliance than gliadin IgG antibody concentrations.
IgG antibody is more sensitive but less specific than IgA antibody. Since IgA deficiency is relatively common among celiac patients, the combined use of IgA and IgG antibodies is recommended for diagnosis.
Gliadin deamidated IgA and IgG antibodies may be ordered together or separately. If the antibody is not clearly specified, both the IgA and IgG assays will be performed. Please contact the MLabs Client Services Center for additional clinical information regarding Celiac Disease and associated laboratory testing.
