Gliadin antibodies (AGA) are produced to attack Gliadin, which is a portion of the protein found in gluten.
A gliadin antibodies test is used as part of an evaluation for celiac disease.
Celiac disease is an autoimmune disorder in which the body's immune system mistakenly perceives gluten (found in wheat, barley, rye, and oats) as a foreign invader.
The antibodies are divided into two groups:
IgA is more useful in detecting celiac disease because it's made in the small intestine, where gluten causes inflammation and irritation in sensitive people.
IgG levels are less specific to celiac disease, but may still be useful in diagnosing autoimmune problems, especially in people who are deficient in IgA.
By measuring the levels of both types of gliadin antibodies in the blood, doctors can assess the immune system's response to gluten.
It is important to eat gluten with each meal for 6 weeks prior to this test. This maximises the chance of detecting coeliac disease on the test. If this advice isn’t followed then there is a danger of coeliac disease being missed by the test.
