Wide variations in volume of the aspirate will be indicative of incomplete aspiration or contamination. Each fraction of duodenal fluid is to be chilled and subsequently analyzed for volume and bicarbonate concentration. A duodenal aspirate obtained as under Pancreatic Function Testing is submitted for cytopathological examination. The patient should have fasted for at least 12 hours prior to beginning the test. However, the biological activity of Secretin-Ferring will not be significantly decreased by storage at temperatures up to 25 C for up to 3 weeks.
