Interactive LRINEC Score calculator for necrotizing fasciitis. Requires the calculator gadget.
Usage: {{LRINEC Calculator}}
LRINEC Score
| Lab Value | Select |
|---|---|
| CRP (mg/L) | 1 <150 (0) ≥150 (+4) |
| WBC (×10³/μL) | 1 <15 (0) 15–25 (+1) >25 (+2) |
| Hemoglobin (g/dL) | 1 >13.5 (0) 11–13.5 (+1) <11 (+2) |
| Sodium (mEq/L) | 1 ≥135 (0) <135 (+2) |
| Creatinine (mg/dL) | 1 ≤1.6 (0) >1.6 (+2) |
| Glucose (mg/dL) | 1 ≤180 (0) >180 (+1) |
| LRINEC Score | / 13 |
| Interpretation | |
|---|---|
| <6 | Low risk — <50% probability of necrotizing fasciitis. Consider other diagnoses but maintain clinical suspicion. |
| 6–7 | Moderate risk — 50–75% probability. Consider surgical consultation and advanced imaging. |
| ≥8 | High risk — >75% probability of necrotizing fasciitis. Urgent surgical consultation for exploration. |
