Background and clinical significance

Early detection and management of pancreatic insufficiency is essential to optimize health outcomes in patients with known or suspected exocrine pancreatic dysfunction such as cystic fibrosis. The gold standard measures for assessment of pancreatic function are direct pancreatic stimulation tests, which have numerous limitations. Estimation of fecal elastase-1 levels to determine pancreatic function is an attractive alternative and provides useful clinical information.
