Methods
Enzyme immunoassay (EIA)
Clinical Utilities
Use: Detection of antibodies to aid in the diagnosis of gluten-sensitive enteropathy (GSE), such as celiac disease and dermatitis herpetiformis
Limitations: A negative result does not rule out celiac disease. The inclusion of the tTG IgG autoantibodies is important because it is not uncommon for celiac patients to be IgA deficient. Results of this assay should be used in conjunction with clinical findings and other serological tests.
