By comparing the creatinine level in urine with the creatinine level in blood , the creatinine clearance test estimates the glomerular filtration rate (GFR) . GFR is a measure of how well the kidneys are working, especially the kidneys' filtering units. These filtering units are called glomeruli.
This formula is applicable only if the serum creatinine is stable.
Creatinine Clearance = [[140 - age(yr)]*weight(kg)]/[72*serum Cr(mg/dL)] (multiply by 0.85 for women).

Creatinine Clearance (CrCl) Calculator: allows the creatinine clearance to be estimated from the serum creatinine in a patient with a stable serum creatinine.
