Quest Diagnostics gives you the testing solutions you need to aid in the diagnosis and management of your patients with celiac.

Blood tests are the first step in diagnosing celiac disease and can help determine the need for further evaluation. It is important that patients continue to consume gluten as normal and do not start a gluten-free diet, as this can result in false negative test results. We offer the most specific serologic marker available—deamidated gliadin peptide.
