Which enzyme pair is typically used to screen for acute pancreatitis?

• A. Amylase and lipase
• B. Lipase and trypsin
• C. Amylase and trypsin
• D. Amylase, lipase, and trypsin

Answer: (A)

When screening for acute pancreatitis, the goal is to detect markers that reflect pancreatic injury in the blood. Amylase and lipase are the classic pairs because both originate from the pancreas and rise in response to inflammation. Amylase appears early, within hours, but its levels can normalize relatively quickly and can be elevated in non-pancreatic conditions. Lipase, on the other hand, tends to be more specific to pancreatic tissue and remains elevated longer, providing a more reliable signal over time. Using both together increases sensitivity and diagnostic accuracy compared with using either enzyme alone, which is why this pairing is the typical choice. The other options are less appropriate because they either omit lipase or include trypsin, which is not routinely used for initial pancreatitis screening due to its lower diagnostic value.
