Individuals with celiac disease are sensitive to gluten, a component found in wheat, rye, barley, and oats. When a person with celiac disease consumes gluten, the gluten induces an abnormal immune reaction in the body. Immune cells attack the lining of the small intestine, damaging it leading to serious health complications.

Celiac disease has a genetic component, where people who inherit certain genetic variants are more likely to develop the disease. Almost all people with celiac disease have at least one of these genetic variants.

You can find out if you are at risk with this DNA test. As this is a DNA test it is not necessary to consume foods containing gluten before taking this test.
