Overview
LRINEC is a diagnostic scoring system used to distinguish necrotizing fasciitis from other soft tissue infections.
Laboratory risk indicator for necrotizing fasciitis (LRINEC) scoring system
LRINEC is a diagnostic scoring system used to distinguish necrotizing fasciitis from other soft tissue infections.[1]
| Variable | Score | ||||
|---|---|---|---|---|---|
| 0 | +1 | +2 | +3 | +4 | |
| C-reactive protein (mg/dL) | <150 | >150 | |||
| Total White Blood Cell Count (/mm3) | <15 | 15-25 | >25 | ||
| Hemoglobin (g/dL) | <13.5 | 11-13.5 | <11 | ||
| Sodium (mmol/L) | ≥135 | <135 | |||
| Creatinine (μmol/L) | <141 | >141 | |||
| Glucose (mmol/L) | <10 | >10 | |||
- Score of ≤5 indicates low risk
- Score of 6-7 indicates intermediate risk
- Score of ≥8 indicates high risk
