What is the primary purpose of PLI (pancreatic lipase immunoreactivity)?

• A. Diagnosis of pancreatitis (best in dogs)
• B. Diagnosis of kidney disease
• C. Assessment of intestinal permeability
• D. Evaluate liver function

Answer: (A)

Pancreatic lipase immunoreactivity is a blood test that measures how much lipase comes from the pancreas. When the pancreas becomes inflamed (pancreatitis), pancreatic lipase leaks into the bloodstream, so PLI levels rise. This makes the test particularly useful for confirming pancreatitis, and within veterinary medicine there are species-specific versions (canine PLI and feline PLI) to optimize accuracy. The test is designed to detect pancreatic disease, not kidney disease, intestinal permeability, or liver function, because those conditions are evaluated with different markers. So, the primary purpose is to diagnose pancreatitis, especially in dogs, where this test is especially informative.
