Which statement about amylase in acute pancreatitis is correct?

• A. It decreases early
• B. It rises within 24 hours and typically returns to normal within 48-72 hours
• C. It is not elevated
• D. It peaks after a week

Answer: (B)

In acute pancreatitis, amylase appears in the blood early after pancreatic injury because damaged pancreatic cells release the enzyme. The typical pattern is a rise within the first 24 hours after symptoms begin, followed by a return to normal levels within about 2 to 3 days (48–72 hours). This course reflects both the speed of leakage of the enzyme into the bloodstream and its clearance by the kidneys as inflammation subsides. So, saying that amylase rises within 24 hours and usually normalizes within 48–72 hours accurately captures its common time course in acute pancreatitis.
