Order Celiac Disease Antibody Test | IgG & IgACeliac disease is an autoimmune condition triggered by dietary gluten, and its diagnosis rests heavily on laboratory evidence. The Celiac Disease Antibody Test measures specific immunoglobulins—IgG and IgA class antibodies against tissue transglutaminase and gliadin—that the immune system produces when it reacts to gluten. This panel offers a structured way to examine those antibody signals in the blood.
About Celiac Disease Antibody Test | IgG & IgA in Arlington Heights
Antibody testing is a cornerstone of celiac disease evaluation, but it is one piece of a broader clinical picture.
Tissue transglutaminase (tTG) is an enzyme that modifies gluten peptides, and antibodies against it are widely regarded as the most sensitive and specific serologic marker for celiac disease. The IgG and IgA forms of tTG antibody can behave differently, particularly in individuals with selective IgA deficiency, which is why testing both isotypes improves detection.
Gliadin is a component of gluten, and antibodies against gliadin—both IgG and IgA—were among the earliest serologic markers used in celiac testing. Although deamidated gliadin peptide (DGP) assays have largely replaced native gliadin antibody tests in modern practice, gliadin antibody measurements still appear in some panels and can provide supporting information when interpreted alongside tTG results.
No single antibody result stands alone. IgA deficiency, age, immune status, and gluten intake before testing can all influence antibody levels. A qualified healthcare professional interprets these values in the context of symptoms, family history, and—when appropriate—intestinal biopsy findings. This test is a screening and monitoring tool, not a self-contained diagnosis.
