Clinical Significance

Pancreatic Exocrine Cell Antibody - Antibodies to pancreatic exocrine cells (ExPA) have been suggested as a very specific Crohn's Disease (CD) serological marker. Clinical studies reported a prevalence of 30-50% in CD patients. In spite of the relatively low sensitivity, ExPA can detect a subpopulation of CD patients that are negative for other CD markers (ASCA IgG, ASCA IgA), thus being very useful in combination with other IBD tests.
