Methods
Enzyme Immunoassay (EIA)
Clinical Utilities
Detection of antibodies to aid in the diagnosis of gluten-sensitive enteropathy (GSE), such as celiac disease and dermatitis herpetiformis
Limitations: A negative tTG IgA result in an untreated patient does not rule out gluten-sensitive enteropathy. This result can often be explained by selective IgA deficiency, a relatively frequent finding in celiac disease. Results of this assay should be used in conjunction with clinical findings and other serological tests.
