Test Overview
Test Methodology

Multiplex Flow Immunoassay

Test Usage

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.

Reference Range *

Negative (0-14 U/mL)

* Reference ranges may change over time. Please refer to the original patient report when evaluating results.

Test Limitations

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.
