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 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.

Reference Range

Negative (0-14 U/mL)

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