Creatinine clearance

a mathematical calculation of the total amount of creatinine excreted in the urine over a period of time, as an indication of renal function

Description
The calculation is: creatinine clearance [ml/min] = urine creatinine concentration [ml/dl] × volume of urine [ml/24 hour]/(plasma creatinine concentration [mg/dl] x 1440 [min/24 h]).
