Order Celiac Disease Antibody Test | IgG & IgACeliac disease is an autoimmune condition triggered by gluten, and its diagnosis relies heavily on serologic testing. The Celiac Disease Antibody Test measures specific antibodies in the blood that are associated with the immune response to gluten. This panel includes both IgG and IgA classes of tissue transglutaminase and gliadin antibodies, providing a broad view of the humoral response.
About Celiac Disease Antibody Test | IgG & IgA in Merced
Understanding the antibodies involved in celiac disease helps clarify what the test results can indicate.
Tissue transglutaminase (tTG) is an enzyme that modifies gliadin peptides, and the immune system may produce antibodies against it. IgA anti-tTG is the most sensitive and specific serologic marker for celiac disease in individuals who are not IgA deficient. IgG anti-tTG is useful when IgA deficiency is present or suspected.
Gliadin is a component of gluten, and antibodies against deamidated gliadin peptides (DGP) can also be detected. IgA and IgG anti-DGP tests are particularly helpful in children under two years old and in cases where tTG results are equivocal. Combining these markers increases the overall detection rate.
The test requires a blood sample, and no special preparation is typically needed beyond following the lab's instructions. Results are usually available within one to three business days. It is important to note that antibody levels can be influenced by gluten consumption; individuals already on a gluten-free diet may have negative results despite having celiac disease.
