Test Overview
Multiplex Flow Immunoassay
Marker of celiac disease associated with gluten-sensitive enteropathy or dermatitis herpetiformis. A positive result indicates the presence of Gliadin IgA 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.
Negative (0-14 U/mL)
* Reference ranges may change over time. Please refer to the original patient report when evaluating results.
IgA antibody is more specific but less sensitive than IgG antibody. Since IgA deficiency is relatively common among celiac patients, the combined use of IgA and IgG antibodies is recommended for diagnosis. Results are unreliable in patients with extremely low total IgA values.

Additional Information
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.
