New Test Algorithms for Celiac Disease

Mayo Medical Laboratories test algorithms for celiac disease use a reflex approach that provides a cost-effective alternative to ordering individual tests when evaluating a patient with suspected celiac disease. The goal of these algorithms is to provide the most appropriate selection of tests for each patient, while maintaining the highest possible sensitivity and specificity.

The following Hot Topic presentations discuss the algorithmic approach to diagnostic testing for celiac disease.

Hot Topic

Melissa Snyder, Ph.D., Director of the Antibody Immunology Laboratory in the Division of Clinical Biochemistry and Immunology at Mayo Clinic, discusses the new celiac disease panels available from Mayo Medical Laboratories and the algorithmic approach of each.

Clinical Insight

Joseph Murray, M.D., a practicing gastroenterologist and Professor of Medicine and Immunology at Mayo Clinic, as well as Director of Mayo’s Celiac Disease Program, discusses several cases of celiac disease and the appropriate diagnostic testing for each situation.
