Methodology · worked example, guidelines & full notes
A low score does NOT exclude necrotising fasciitis.
When to use
Lab-based adjunct when necrotising fasciitis is considered.
How it works
CRP ≥ 150 (4); WBC 15–25 (1)/>25 (2); Hb 11–13.5 (1)/<11 (2); Na < 135 (2); Cr > 141 µmol/L (2); glucose > 10 (1). ≥ 6 suspicious, ≥ 8 high.
Key points
- A low score does NOT exclude necrotising fasciitis.
- Diagnosis remains clinical and surgical.
- Do not delay exploration for a reassuring score.

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.
| CRP | 200 mg/L |
|---|---|
| WBC | 18 ×10⁹/L |
| Haemoglobin | 12 g/dL |
| Sodium | 133 mmol/L |
| Creatinine | 150 µmol/L |
| Glucose | 11 mmol/L |

- Risk：≥ 8 — high risk
- Caution：A low score does NOT exclude necrotising fasciitis — it remains a clinical/surgical diagnosis.
