title: Radioselenium in duodenal aspirate as an assessment of pancreatic exocrine function.
abstract: A new test of pancreatic exocrine function is described in which radioselenium is measured in duodenal aspirate after an intravenous injection of (75)Se-selenomethionine and administration of a Lundh test meal. Duodenal (75)Se activity gave good separation between normals and subjects with disease of the exocrine pancreas and correlated well with trypsin levels in the aspirate.
