WebCreatinine clearance (Ccr) measurement has been widely used and correlates well with inulin clearance within the normal range of GFR.14 Creatinine is an amino acid derivative produced in muscle cells. It is freely filtered, and about 10% of the creatinine found in urine is secreted by the proximal tubules.
