Clinical Significance
Serological methods of detecting Immunoglobulin A (IgA) antibodies to gliadin, endomysium (EMA), reticulin, and tissue transglutaminase are routinely used for diagnosing both symptomatic and asymptomatic patients with Celiac Disease (CD). Since Immunoglobulin A (IgA) deficiency is 10 to 15 times more common in patients with Celiac Disease than in healthy subjects, IgG-specific antibody tests for endomysium are useful for the identification of IgA-deficient patients with CD.
