Serial measurement of serum pancreatic lipase immunoreactivity and trypsin‐like immunoreactivity concentrations in dogs and cats with diabetes mellitus

Serum specific pancreatic lipase concentrations indicative of pancreatitis were relatively common in both dogs and cats with diabetes mellitus. Serum trypsin-like immunoreactivity concentrations indicative of exocrine pancreatic insufficiency were less common and were only observed in dogs. Repeated testing for concurrent exocrine pancreatic disorder in dogs and cats with diabetes mellitus may be indicated even if the patient is subclinical.
