LRINEC score
Laboratory Risk Indicator for Necrotizing Fasciitis (LRINEC) Score (Wong et al)
Laboratory Risk Indicator for Necrotizing Fasciitis (LRINEC) Score[1]
Has not been prospectively validated, index of suspicion is key and 10% of the patients with a score < 6 had Necrotizing Fasciitis. A score > 6 has PPV of 92% and NPV of 96% for necrotizing fasciitis.
- CRP (mg/L) ≥150: 4 points
- WBC count (×103/mm3)
- <15: 0 points
- 15–25: 1 point
- >25: 2 points
- Hemoglobin (g/dL)
- >13.5: 0 points
- 11–13.5: 1 point
- <11: 2 points
- Sodium (mmol/L) <135: 2 points
- Creatinine (umol/L) >141: 2 points
- Glucose >180 mg/dL (10 mmol/L): 1 point
