Glasgow-Imrie Score Calculator (Acute Pancreatitis)

The Glasgow-Imrie score (mnemonic PANCREAS) grades the severity of acute pancreatitis from eight criteria assessed within 48 hours — PaO₂, age, neutrophil/white-cell count, calcium, renal urea, LDH/AST, albumin and glucose — each scoring one point. A score of 3 or more predicts severe acute pancreatitis.

Quick answer

The Glasgow-Imrie score (PANCREAS) adds one point each for PaO₂ under 60 mmHg, age over 55, white-cell count over 15 × 10⁹/L, calcium under 8 mg/dL, urea over 16 mmol/L, LDH over 600 IU/L (or AST over 200), albumin under 3.2 g/dL, and glucose over 180 mg/dL, assessed within 48 hours. A score of 3 or more predicts severe acute pancreatitis.

0/ 8

Predicted mild acute pancreatitis (0–2)

The Glasgow-Imrie score is 0/8: predicted mild acute pancreatitis (0–2). A score of 3 or more (assessed within 48 hours) predicts severe acute pancreatitis.

This is a prognostic reference estimate, not a diagnosis or a measure of the cause. A clinician interprets it alongside the full clinical picture.

How to use the Glasgow-Imrie calculator

1Tick the eight PANCREAS criteria. Within 48 hours of admission, tick each criterion that applies: low PaO₂, age over 55, high white cells, low calcium, high urea, high LDH/AST, low albumin, and high glucose.
2Read the total. The tool totals the points (0–8).
3Interpret the band. A score of 3 or more predicts severe acute pancreatitis and prompts closer monitoring — interpreted by a clinician alongside other assessment.

Frequently asked questions

What does the PANCREAS mnemonic stand for?⌄

PANCREAS stands for PaO₂ (low), Age (over 55), Neutrophils (white cells over 15), Calcium (low), Renal (urea high), Enzymes (LDH/AST high), Albumin (low) and Sugar (glucose high) — the eight factors of the modified Glasgow (Imrie) score.

What Glasgow-Imrie score means severe pancreatitis?⌄

A score of 3 or more, assessed within the first 48 hours, predicts severe acute pancreatitis in the original study. It is a prognostic flag for closer monitoring, not a diagnosis of the cause.

When should the score be calculated?⌄

The criteria are designed to be assessed within 48 hours of admission, because several values (such as calcium and urea) evolve over the first day or two of the illness.

Is my data stored?⌄

No. The calculator runs entirely in your browser; nothing you enter is sent to a server.
