Which test is most specific for pancreatitis in dogs?

Which test is most specific for pancreatitis in dogs?

• A. PLI
• B. TLI
• C. Fecal fat test
• D. CBC and chemistry panel

Answer: (A)

Pancreatic lipase immunoreactivity directly measures the enzyme produced by the pancreas, so when pancreatitis is present, this lipase level rises and is detected by the test. In dogs, this assay has high specificity for pancreatic disease, meaning a positive result strongly supports pancreatitis and a normal result makes it unlikely. The other options don’t target pancreatic inflammation as directly: trypsin-like immunoreactivity is more commonly used for exocrine pancreatic insufficiency and can be variable for pancreatitis; fecal fat testing looks at fat digestion and malabsorption, which can occur for many reasons and isn’t a specific marker of pancreatic inflammation; CBC and chemistry panels provide nonspecific clues but can be normal or misleading in pancreatitis.
