NCCAOM Biomedicine Board Practice Exam

The most specific lab test for diagnosing acute pancreatitis is high lipase levels. While both amylase and lipase are enzymes that can elevate in the presence of pancreatitis, lipase is generally more specific to pancreatic injury. High lipase levels can remain elevated for a longer duration than amylase levels, which can return to normal more quickly.

In acute pancreatitis, lipase is released from damaged pancreatic cells into the bloodstream, making it a reliable marker for diagnosis. The elevation of lipase can sometimes occur even in mild cases or those that may not present with significantly elevated amylase levels.

High glucose levels and low triglycerides do not provide specific evidence of pancreatitis. While patients with pancreatitis may experience hyperglycemia due to impaired insulin production or sensitivity, these findings are not unique to pancreatitis and can occur in a variety of other conditions. Similarly, low triglycerides do not correlate directly with the diagnosis of acute pancreatitis. It's the elevation of lipase that distinctly indicates pancreatic pathology, distinguishing it from other conditions that can also elevate amylase.
