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.

  1. CRP (mg/L) ≥150: 4 points
  2. WBC count (×103/mm3)
    • <15: 0 points
    • 15–25: 1 point
    • >25: 2 points
  3. Hemoglobin (g/dL)
    • >13.5: 0 points
    • 11–13.5: 1 point
    • <11: 2 points
  4. Sodium (mmol/L) <135: 2 points
  5. Creatinine (umol/L) >141: 2 points
  6. Glucose (mmol/L) >10: 1 point

Grouping by Scores

  • Low Risk: score 5
  • Moderate Risk: score 6– 7
  • High Risk: score >8
