Estimated Creatinine Clearance (Cockcroft-Gault formula)
CCr=(140-Age)*mass(kg)*(0.85 for females)/[72*Serum creatinine(mg/dl)]
Age(in years)
Weight (in Kg)
Serum Creatinine (mg/dl)
Creatinine Clearance (in ml/min) per 1.73m² Body Surface area
Females
Males
Extremely obese or slim patients should have their CCr corrected for their actual BSA
corrected CCr = CCr*1.73/BSA
Normal range:
women: 88-128ml/min
men: 97-137ml/min
