Creatinine Clearance (CrCl) Formula

Creatinine Clearance is a test performed to find the GFR (Glomerular filtration rate) in the body. This formula is used to calculate the estimated creatinine clearance rate (CrCl) in the body. You can use a different GF for calculating the eCcr for male and female.


Estimated Creatinine Clearance = [ [ 140 - age] x weight x GF ] / [ 72 x serum Cr]


GF = Gender Correction Factor,
If male, GF = 1,
If female, GF = 0.85

GFR is the measure of the rate of the functioning of kidneys and its filtering units. The estimated CrCl can be calculated from the stable serum creatinine in a person.
