A patient, admitted with acute abdominal and back pain, is diagnosed with acute pancreatitis after which of the following diagnostic tests?
1. serum lipase level
2. hemoglobin level
3. hematocrit level
4. secretin stimulation test
1
Rationale: Lipase levels in the serum will be elevated if pancreatic inflammation is present. Lipase is currently the best enzyme to identify acute pancreatitis. Hemoglobin and hematocrit levels are not used to help diagnose the presence of acute pancreatitis.
The secretin stimulation test helps determine pancreatic activity but will not necessarily aid in the diagnosis of acute pancreatitis.
