Which test is best for diagnosing pancreatitis in dogs?

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

Answer: (A)

Diagnosing pancreatitis in dogs relies on a test that directly reflects pancreatic inflammation, not just general signs of illness. Pancreatic Lipase Immunoreactivity (PLI) measures the amount of pancreatic lipase in the bloodstream, which increases specifically when the pancreas is inflamed. This makes it the most reliable single test for pancreatitis because of its high sensitivity and specificity to pancreatic disease. Other tests provide indirect information or look for different problems: the trypsin-like immunoreactivity test is mainly used for exocrine pancreatic insufficiency and can be normal in pancreatitis, so it isn’t ideal for diagnosing it; fecal fat testing assesses fat absorption rather than pancreatic inflammation; and a CBC/chemistry panel can show nonspecific changes or be normal even with pancreatitis. If available, a quantitative Spec cPL or a qualitative SNAP PLI can be used, but the central idea is that measuring pancreatic lipase is the best way to confirm pancreatitis.
