Antigliadin Antibodies [AGA]

  • Gliadin is part of the gluten protein found in wheat. Gliadin antibodies, also known as antigliadin antibodies (AGA) form in some individuals who are exposed to gluten over a period of time. This is one of several tests used in the diagnosis of celiac disease and other gluten-sensitive conditions.
  • AGA testing may be used to rule out celiac disease in patients with anemia or abdominal pain, or as part of allergy testing.
  • Typically both the IgA and IgG types of antibodies are measured.
