title: The diagnostic value of faecal trypsin estimation in chronic pancreatic disease.
abstract: Faecal trypsin levels have been estimated by a photometric azo-casein method in 242 children and 45 adults. Analysis of the results shows that this is not a specific test of pancreatic dysfunction but that it appears to be a useful screening test for the selection of patients who may have severe pancreatic disease and on whom further specific investigations should be performed.
