Creatinine Clearance Estimate by Cockcroft-Gault Equation

Input:
Sex Male (1)

Female (0.85)
Age
Serum Creat
Weight
Result:
Creat Clear
 
Decimal Precision:
CreatClear = Sex * ((140 - Age) / (SerumCreat)) * (Weight / 72)
  • 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. (1), represent the values that will be used.
  • 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.
