Prediction of glomerular filtration rate from serum creatinine, age, sex and body weight.
The accuracy and precision of estimates of glomerular filtration rate (GFR) from serum creatinine, age, sex and body weight using the methods proposed by Cockroft and Gault and by Siersbaeck-Nielsen et al, were determined in 234 subjects on 574 occasions. The two methods gave almost identical estimates of GFR. As reference for determination of GFR plasma clearance of 51Cr-EDTA as described by Bröchner-Mortensen was used. The estimates of GFR gave a systematic deviation of about 10 ml/min and a precision of about +/- 15 ml/min (1 SD) in the GFR range between 30 and 90 ml/min.
