creatinine clearance(redirected from Creatinin clearance)
measurement of the clearance of endogenous creatinine, used for evaluating the glomerular filtration rate.
creatinine clearanceNephrology The ratio of the rate of creatinine excretion in urine to its concentration in serum, a value that reflects the body's ability to excrete creatinine; it is used to diagnose and monitor renal function
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.
