Gliadin IgG LIS Code: Gliadin IgG

What Is Gliadin IgG?

Gliadin IgG refers to the presence of Immunoglobulin G (IgG) antibodies in the blood that react to gliadin, a protein component of gluten found in wheat, barley, and rye. These antibodies are produced by the immune system when it identifies gliadin as a potential threat.

Role of IgG Antibodies in Gluten Sensitivity

The immune system may produce IgG antibodies against gliadin in individuals with or without celiac disease or non-celiac gluten sensitivity. However, the presence of Gliadin IgG does not confirm a specific gluten-related disorder and can also be associated with other conditions, including infections and autoimmune diseases.

Limitations of Gliadin IgG Testing

Gliadin IgG testing is not a specific diagnostic tool for celiac disease or gluten sensitivity. A positive result alone is not sufficient to confirm a diagnosis. It is not recommended as a stand-alone test due to its low specificity and potential for false positives.

When Gliadin IgG Testing May Be Considered

Gliadin IgG testing may have clinical value in particular scenarios, such as:

Individuals already on a gluten-free diet

Patients with known IgA deficiency, where standard celiac tests may yield false-negative results

Supplementary evaluation alongside other serological or genetic tests
