A non-invasive celiac home test could be the future of diagnosing gluten sensitivity. Previously, people had to reintroduce gluten into their diet, endure symptoms and undergo an invasive procedure in order to be diagnosed with celiac disease. Celiac Disease Foundation is proud to play a role in supporting the research that is changing this future.

There are two types of at-home celiac tests: antibody tests and genetic tests. Antibody tests can look for antibodies that are associated with celiac disease in a blood sample obtained by pricking the finger. These antibodies are usually only elevated in people with celiac disease.

However, they may also be elevated in some people with gluten sensitivity who are following a gluten-free diet. This makes it difficult to interpret antibody test results and is why it is important to discuss your results with a health care professional.

Genetic tests, on the other hand, can check your DNA to see whether you have certain variants and combinations of genes that increase your risk of developing gluten sensitivity or celiac disease. The patented GLUTOGEN GI DNA test, for example, tests for the genetic markers DQ2, DQ8, HLA-DQA1*05 and HLA-DQB1*02, which are most closely linked to these conditions. The company states that the test is fast, simple and confidential. It includes a kit with lancets for collecting the sample, a prepaid envelope and a secure online portal. People can receive their results within 10 days of sending the sample.
