This Creatinine Clearance Calculator evaluates renal function via the Cockcroft Gault equation and can offer information on the filtration function of the kidneys.CrCl explained
Creatinine clearance is one of the renal indicators of the kidney filtration rate. The most common method to determine it is via the Cockcroft Gault equation.
The CrCl calculator requires the patient’s gender, age, height and weight and the serum creatinine. The formulas used are gender specific:
CrCl for men = [(140 - age) x Weight in kg] / (Serum Creatinine in mg/dL x 72)
CrCl for women = [(140 - age) x Weight in kg x 0.85] / (Serum Creatinine in mg/dL x 72)
These can be adapted for use when serum creatinine is expressed in µmol/L:
CrCl for men = [(140 - age) x Weight in kilograms x 1.23] / (Serum Creatinine in µmol/L)
CrCl for women = [(140 - age) x Weight in kilograms x 1.04] / (Serum Creatinine in µmol/L)
The calculation of the ideal body weight takes place via the Devine formula:
Male = 50 kg + (2.3 x (Height in inches - 60))
Female = 45.5 kg + (2.3 x (Height in inches - 60))
