9169. Gliadin, IgG antibodies
Description
IgG antibodies to gliadin appear when gluten enters the gastrointestinal tract in predisposed individuals and are a marker of gluten-sensitive enteropathy. This condition may manifest with symptoms such as vomiting, abdominal pain, dermatitis, anemia, visual disturbances, and epilepsy.

The test is usually performed as part of a panel that includes testing for IgA antibodies to gliadin, antibodies to tissue transglutaminase, and antibodies to endomysium.
