Glomerular filtration rate (GFR) is commonly assessed by measurement of endogenous creatinine clearance (Ccr). Several formulae have been described to calculate Ccr from plasma creatinine. I have evaluated the effectiveness of four formulae in 35 healthy subjects (21M and 14F, 18-34 years) and in 41 patients (24M, 17F, 20-69 years) attending a renal clinic with diminished renal function (serum ...
