ANTI DEAMIDATED GLIADIN PEPTIDE – IGG

The anti-deamidated gliadin peptide (DGP) IgG test detects the presence of IgG antibodies against deamidated gliadin peptides. This test is particularly useful for diagnosing celiac disease in individuals with IgA deficiency or inconclusive IgA-based test results. Elevated levels of anti-DGP IgG antibodies indicate an immune response to gluten, which supports the diagnosis of celiac disease. This test complements other serological tests like tTG-IgA and EMA-IgA to provide a comprehensive assessment for celiac disease. Monitoring these antibody levels can help evaluate the effectiveness of a gluten-free diet in patients with celiac disease.
