Measurement of the canine specific pancreatic lipase concentration (cPLI) in serum currently constitutes the most practical, widespread, and reliable method to aid in diagnosing canine pancreatitis [4,5], with a sensitivity of 72–94% and a specificity of 80–100% across all severities and categories of pancreatitis [6]. The gene discussed is PNLIP; the disease is pancreatitis.
