Changes

All pancreatic enzymes increase following renal failure (apart from PLI) making it difficult to determine the true cause of the increase. However increases of three fold are mainly due to pancreatitis, whereas five fold increases are rarely not found to be pancreatitis. Rises in lipase, amylase and phospholipase A2 may also be hepatic, gastric, intestinal or neoplastic in origin.

'''In cats:''' Amylase and lipase are of no diagnostic value. Serum fTLI is a specific test for exocrine pancreatic function without azotaemia buts the test's sensitivity varies between 30% and 60%. In comparison, the serum fPLI has been found to be more specific and sensitive in diagnosing feline pancreatitis.

'''In cats:''' Amylase and lipase are of no diagnostic value. Serum feline trypsin-like immunoreactivity (fTLI) is a specific test for exocrine pancreatic function but the test's sensitivity varies between 30% and 60%. In comparison, the serum feline pancreatic lipase immunoreactivity test (fPLI) has been found to be more specific and sensitive in diagnosing feline pancreatitis.

 

'''In dogs:''' Marked increases in serum lipase is a more reliable marker than amylase. However corticosteroid administration raises lipase activity by up to five fold. Serum canine pancreatic lipase immunoreactivity (cPLI) is the most sensitive and specific test for diagnosing canine pancreatitis.
