Deamidated Gliadin Peptide IgA details
What Deamidated Gliadin Peptide IgA shows
Deamidated gliadin peptide (DGP) IgA is an antibody used to help screen for celiac disease, an autoimmune reaction to gluten that damages the small intestine. It's a somewhat more specialized celiac marker than the standard tissue transglutaminase (tTG) test, and is particularly useful in young children, whose immune systems don't always produce a strong tTG-IgA response, and in situations where tTG results are borderline or don't match the clinical picture. As with other celiac antibody tests, an accurate result depends on continuing to eat gluten leading up to the test, since a gluten-free diet can cause these antibodies to normalize even if celiac disease is present.
Tests that include Deamidated Gliadin Peptide IgA
This test measures IgA antibodies to deamidated gliadin peptide. It is used to aid in the diagnosis of gluten-sensitive enteropathies such as celiac disease.
- 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.
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.
