Clinical takeaway

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.

  • Diagnostic value：> 3× ULN supports acute pancreatitis; more specific than amylase and stays elevated longer
  • Mild elevation：Renal failure, other acute abdomen, diabetic ketoacidosis, etc.
ViewPancreatitis diagnosis

→Pancreatic enzymesAcute pancreatitis diagnosis (2 of 3)

  • Criteria：① typical epigastric pain ② lipase/amylase > 3× ULN ③ characteristic imaging (any 2)
  • Note：The enzyme level does not reflect severity
  • Severity：Use BISAP/Ranson/CTSI/APACHE-II, not the enzyme value

FAQ

Frequently asked questions

What are the limits and cautions when using Amylase / Lipase Interpretation?
For licensed clinicians and clinical researchers. Interpret results with history, investigations and local protocols; not a diagnosis or prescription, and not a substitute for multidisciplinary decision-making or local guidelines.
Does Amylase / Lipase Interpretation upload patient data? Where is it calculated?
Calculation runs locally in the browser; inputs and results are not uploaded. For licensed clinicians only; interpret with history, investigations and local protocols — not a diagnosis or prescription.
How is Amylase / Lipase Interpretation calculated in practice? Can you show a worked example?
