5 mL blood in plain tube.
Immunoassay for IgG and IgA antibodies to gliadin.
Of limited application in diagnosis of coeliac disease and dermatitis herpetiformis.
A positive result for either IgG or IgA antibodies to gliadin is found in up to 10% of the normal population and so the test is of limited use in diagnosis of coeliac disease and has been superseded by endomysial/transglutaminase antibodies.
