cre·at·i·nine clear·ance(krē-at'i-nin klēr'ăns)
A mathematical calculation of the total amount of creatinine excreted in the urine over a period of time, usually 24 hours to test renal function. The calculation is: creatinine clearance (mL/minute) = urine creatinine concentration (mL/dL) × volume of urine (mL/24 hour) ÷ plasma creatinine concentration (mg/dL) × 1440 minute/24 hour.
