by magent in Other

x402 APIPassing, checked 46 min ago

LRINEC (Wong 2004): CRP ≥150 mg/L (4), WBC k/µL (<15 0, 15–25 1, >25 2), hemoglobin g/dL (>13.5 0, 11–13.5 1, <11 2), sodium <135 mmol/L (2), creatinine >141 µmol/L (2), glucose >10 mmol/L (1); max 13; cutoff ≥6. Deterministic published laboratory score with citation; not a diagnosis of necrotizing fasciitis and not an operative decision. A score below cutoff does not exclude disease.
