🧪 Amylase / Lipase Interpretation
Interpret amylase and lipase in acute pancreatitis (lipase > 3× ULN), with non-pancreatic elevations and pitfalls. Browser-side reference.
Lipase is more specific and persistent than amylase.

When to use
Apply the enzyme criterion within the Atlanta 2-of-3 diagnosis; grade severity with a scoring system, not the enzyme value.
How it works
Acute pancreatitis = 2 of 3: typical pain, lipase/amylase > 3× ULN, characteristic imaging.
Key points
- Lipase is more specific and persistent than amylase.
- The enzyme level does not reflect severity — use BISAP/Ranson/CTSI.
- Macroamylasaemia gives persistently high amylase without symptoms.
- In hypertriglyceridaemic pancreatitis, check triglycerides.

Worked calculation
The values below come from this tool's own example placeholders and are computed server-side with the formula shown on this page, so the arithmetic can be checked quickly. It demonstrates how to substitute values only — it is not clinical advice and not a real case.

- Hypertriglyceridaemic pancreatitis：Enzymes may rise disproportionately little; check triglycerides
