Renal Function Calculator

Calculate the patient's Glomerular Filtration Rate (GFR) based on their weight (kg) and the creatinine level (mmol/l).

The Renal Function Calculator uses both GFR (Cockcroft-Gault formula) and eGFR (Abbreviated MDRD formula).

To access the Renal Function Calculator, either:
  • Press Ctrl+Alt+W. Click the Renal Function tab.
