SOFA Score Calculator

SOFA Score Calculator for Critical Care. Rising SOFA scores indicate worsening organ dysfunction and can support sepsis severity assessment and ICU monitoring.

How this calculator works

SOFA summarizes organ dysfunction across respiratory, coagulation, liver, cardiovascular, neurologic, and renal systems.

Inputs used

  • PaO2/FiO2
  • Platelets
  • Bilirubin
  • Blood pressure/vasopressors
  • Glasgow Coma Scale
  • Creatinine or urine output

Clinical interpretation

Rising SOFA scores indicate worsening organ dysfunction and can support sepsis severity assessment and ICU monitoring.

Limitations and safety notes

SOFA is a severity and trend tool. It does not diagnose infection by itself and requires accurate physiologic and laboratory inputs.

Editorial review and citation methodology

Reviewed by the Quick Medical Calculator Editorial Team. Last reviewed: June 19, 2026. The review checks calculator inputs, intended population, interpretation, limitations, and source alignment.

  • Prefer original validation studies for scoring systems and prediction tools.
  • Use current specialty society guidance, transplant allocation policy, public health guidance, or regulator resources when they govern clinical use.
  • Include limitations and safety notes when a calculator is population-specific, context-dependent, or unsuitable as a standalone decision tool.
