Order Celiac Disease Antibody Test | IgG & IgACeliac disease is an autoimmune condition triggered by dietary gluten, and its diagnosis rests heavily on serologic testing. The Celiac Disease Antibody Test measures specific immunoglobulins—IgG and IgA class antibodies against tissue transglutaminase and gliadin—that the immune system produces when the small intestine is under gluten-related attack.
About Celiac Disease Antibody Test | IgG & IgA in Norman
Antibodies are the immune system's molecular tags, and in celiac disease they target two distinct proteins: tissue transglutaminase (tTG) and gliadin, a component of gluten.
The test reports IgG and IgA antibodies against both tissue transglutaminase and gliadin. IgA antibodies are the more specific markers for celiac disease, while IgG antibodies can be useful when a person has an IgA deficiency, a condition that occurs more frequently in celiac patients and can otherwise cause false-negative results.
Tissue transglutaminase is an enzyme that modifies gluten peptides, and the immune response against it is considered the most sensitive and specific serologic indicator of celiac disease. Gliadin antibodies were the original serologic marker and remain part of some screening panels, though they are less specific than tTG.
Because antibody production depends on active gluten exposure, results must be interpreted in the context of a person's diet. A negative result does not rule out celiac disease when a patient has already eliminated gluten, and a positive result generally warrants confirmation through endoscopic biopsy of the small intestine.
