In acute pancreatitis, which enzyme is more specific for diagnosis?

Lipase is more specific to pancreatic injury and is preferred for diagnosing acute pancreatitis. It is produced mainly by the pancreas, so its elevation more accurately reflects pancreatic damage than other enzymes. Amylase can rise with pancreatitis but also with non-pancreatic sources like salivary gland disease or renal issues, making it less specific. Additionally, lipase stays elevated longer (often 1–2 weeks), which improves sensitivity if the patient presents after the initial onset. ALT and AST are liver-related enzymes and do not specifically indicate pancreatic injury, so they are not used to diagnose pancreatitis.
