In suspected acute pancreatitis, which enzyme is the gold standard for diagnosis?

In suspected acute pancreatitis, the enzyme test that provides the most reliable diagnosis is lipase. Lipase is far more specific to pancreatic injury than amylase, because it rises primarily in response to pancreatic inflammation and stays elevated much longer. This longer duration makes it easier to detect even if a patient presents after symptoms have begun. Amylase can rise for pancreatitis but isn’t as specific, since it can be elevated in issues outside the pancreas, such as salivary gland problems or renal impairment. In practice, a lipase level elevated to several times the upper limit of normal is highly supportive of pancreatitis, and guidelines favor lipase for diagnostic accuracy. ALT and AST are liver enzymes and aren’t used to diagnose pancreatitis; they may be checked to assess for biliary involvement but do not serve as the primary diagnostic test for pancreatitis. So, lipase is the best enzyme for diagnosing acute pancreatitis due to its higher pancreatic specificity and longer elevation window.
