DGP Celiac Screening - Deamidated Gliadin Peptide (DGP) IgA Test

The analysis of antibodies to deamidated gliadin peptide (DGP) IgA in serum is a laboratory test used to diagnose celiac disease, a condition in which the body has an adverse reaction to gluten found in certain grains such as wheat. This test measures the level of IgA antibodies produced in response to gluten intake. Elevated levels of these antibodies are considered an indicator of inflammation in the small intestine and may help physicians determine the need for further tests or evaluations. This test is recommended for individuals who show symptoms of celiac disease, such as bloating or chronic diarrhea, or who have a family history of the condition.
