Which test is a sensitive and specific test for pancreatitis in dogs?

• A. Canine pancreatic lipase immunoreactivity (cPLI)
• B. Serum creatinine
• C. Urinalysis
• D. Complete blood count

Answer: (A)

Pancreatitis in dogs is best diagnosed by measuring a pancreatic-specific enzyme in the blood. The test that detects canine pancreatic lipase immunoreactivity (cPLI) does exactly that: it detects lipase produced by the pancreas. Because it targets a pancreatic-specific enzyme, it has high specificity, meaning a positive result strongly indicates pancreatitis rather than another condition. It also has high sensitivity, so most dogs with pancreatitis will show an elevated cPLI, making it reliable for identifying affected individuals.

In contrast, serum creatinine reflects kidney function, urinalysis is a broad screening tool for urinary and systemic issues, and a complete blood count provides general hematologic information not specific to pancreatitis. These do not offer the focused diagnostic power needed to confirm pancreatitis, which is why they’re not as useful for this purpose.
