Creatinine Clearance Estimate by Cockcroft-Gault Equation (SI units)

 
Input
 
Sex Female (0.85)

Male (1)
Age  
Serum Creat  
Weight  

 
Result
 
 
Creat Clear  
 
Decimal Precision  
 

 
Notes
  • The default unit of measure for weight is kilograms. Please verify that the correct unit of measure has been selected.
  • This equation provides an estimate of the creatinine clearance (Creat Clear) if the plasma creatinine concentration is stable. Weight is the estimated lean body weight.

 
Equations used
 
CreatClear = 0.0205 * Sex * (140 - Age) * Weight / SerumCreat

 

 
Calculation Details and Variables
  • Equation parameters such as Sex, have two or more discrete values that may be used in the calculation. The numbers in the parentheses, e.g. (0.85), represent the values that will be used.
