Pancreatic injury shows up best with a pancreatic-specific enzyme. Lipase is produced mainly by the pancreas, and when pancreatic tissue is damaged, lipase levels rise in the blood. Because it is more specific to the pancreas—and it stays elevated longer than amylase—it provides a clearer signal for pancreatitis and helps distinguish it from other conditions that might raise enzymes more generally. Amylase can also increase in pancreatitis, but it’s less specific because it can rise with salivary gland issues and other abdominal problems, and it tends to normalize sooner. Lactate dehydrogenase and creatine kinase are broad markers of tissue damage from many sources, so they’re not as useful for pinpointing pancreatitis. Therefore, lipase is the best choice for differentiating pancreatitis in lab testing.
