  Clinical Calculators - Cockroft-Gault Equation  
     
 

The Cockroft-Gault Equation estimates the glomerular filtration rate (eGFR) or creatinine clearance. It relies on the stability of the serum creatinine concentration. Weight is the estimated lean body weight.

You must give information about all four criteria - sex, age (18 years or over) creatinine and weight - in order to estimate glomerular filtration rate / creatinine clearance using the Cockroft-Gault equation.

  Sex:      
    Male  
    Female  
         
  Patient age (years, over 17):   years  
         
  Serum Creatinine:   micromol/L  
         
  Patient weight:   kg
