Clinical Significance

Creatinine Clearance without Glomerular Filtration Rate, Estimated (eGFR) - Creatinine Clearance is used to evaluate the glomerular filtration rate (GFR). Clearance is defined as that volume of plasma from which a measured amount of substance could be completely eliminated into the urine per unit of time. Daily creatinine production is fairly constant except when there is massive injury to muscle.
