Description
A simple blood test is available to test for celiac disease. People with celiac disease who eat gluten have higher than normal levels of certain antibodies in their blood. These antibodies are produced by the immune system because it views gluten (the proteins found in wheat, rye and barley) as a threat. You must be on a gluten-containing diet for antibody (blood) testing to be accurate.
Who should get screened?
- Children older than 3 and adults experiencing symptoms of celiac disease should be tested
- First-degree relatives of people with celiac disease – parents, siblings and children have a 1 in 10 risk compared to 1 in 100 in the general population
- Any individual with an associated autoimmune disorder or other condition, especially type 1 diabetes mellitus, autoimmune thyroid disease, autoimmune liver disease, Down syndrome, Turner syndrome, Williams syndrome, and selective immunoglobulin A (IgA) deficiency
