Raised serum levels of amylase are associated with acute pancreatitis, mumps, certain acute abdominal conditions, and sometimes after the administration of opiates. According to Gray and Somogyi (1), persistently raised levels are to be found also in patients with impaired renal function, though Gross, Parker, Maher, and Power (2) found no significant increase in 63 patients with renal or extrarenal azotemia.
