Deamidated Gliadin Peptide IgG details
What Deamidated Gliadin Peptide IgG shows
Deamidated gliadin peptide (DGP) IgG is an antibody used to help screen for celiac disease, and it's especially useful in people who have selective IgA deficiency — a relatively common condition (more common in people with celiac disease specifically) that can cause standard IgA-based celiac tests, including tTG-IgA, to falsely read as negative even when celiac disease is present. Because of this, total IgA is often checked alongside celiac antibody testing, and if IgA is low, IgG-based tests like this one become the more reliable option. As with other celiac tests, accuracy depends on continuing to eat gluten before testing.
Tests that include Deamidated Gliadin Peptide IgG
This test measures IgG antibodies to deamidated gliadin peptide. It is used to aid in the diagnosis of gluten-sensitive enteropathies such as celiac disease.
- Deamidated Gliadin Peptide IgG An antibody used to help screen for celiac disease, especially useful in people with IgA deficiency.
This test provides a comprehensive evaluation of the antibodies that are characteristic of celiac disease. Celiac disease is also associated with selective IgA deficiency and autoimmune disorders.
- Deamidated Gliadin Peptide IgA An antibody used to help screen for celiac disease, particularly useful in young children or when tissue transglutaminase results are unclear.
- Deamidated Gliadin Peptide IgG An antibody used to help screen for celiac disease, especially useful in people with IgA deficiency.
- Tissue Transglutaminase IgA The primary antibody test used to screen for celiac disease.
- Tissue Transglutaminase (tTG) Antibody (IgG) An antibody used to screen for celiac disease, particularly useful in people with IgA deficiency.
