Gliadin Antibody IgA Test

A gliadin antibodies test is used to diagnose celiac disease. IgA is more helpful in determining celiac disease because it's made in the small intestine, where gluten causes inflammation and irritation in sensitive people. IgG levels are less particular to celiac disease, however, may still be used in diagnosing autoimmune problems, particularly in individuals who are deficient in IgA.

For correct results, you must be on a diet that includes gluten, for instance wheat-containing bread, pasta, and baked goods. The body will only produce antibodies when it's exposed to gliadin. If gliadin has been removed from your diet, there won't be an antibody response to measure. On the day of the test, You may to have wear a T-shirt or short-sleeved shirt to let easier access while drawing the blood.

Celiac disease blood tests determine the amount of particular antibodies in the blood. If the anti-tTG, IgA or IgG test is positive, then the test can also be used to monitor a person with celiac disease and to help assess the effectiveness of treatment; antibody levels will fall when gluten is taken off from the diet.

Blood will be typically drawn from the vein after cleaning the skin with antiseptic solution and wrapping an elastic band around the upper arm to apply pressure to cause the veins to swell with blood. Then a needle is inserted into a vein and blood is withdrawn and collected in a vial or syringe.
