title: Concentration of immunoreactive trypsin and activity of pancreatic isoamylase in serum compared in pancreatic diseases.
abstract: We measured the concentration of immunoreactive trypsin and the enzymic activity of pancreatic isoamylase in sera from 103 patients with pancreatic diseases and 29 other subjects serving as a reference group. Almost all patients with pancreatic diseases had abnormal values for both enzymes. A strong positive correlation between these two variables over a 1000-fold range was observed.
