OBJECTIVE GFR-prediction equations based upon cystatin C and creatinine have better diagnostic performance in estimating GFR than equations based upon only one of the two markers. The present work concerns in what way a comparison between separate estimations of GFR based upon cystatin C (eGFR(cystatin C)) or creatinine (eGFR(creatinine)) can be used to evaluate the diagnostic performance of a ...

Abstract Background and Aims When assessing kidney function, measurement of glomerular filtration rate (mGFR) using an exogenous marker such as iohexol is the gold standard. In this study, we aim to identify similarities differences between iohexol-based mGFR protocols. Method Detailed data on protocols were obtained a standardized survey sent centres in Europe US. It was completed by 15 partic...

BACKGROUND Markers of renal function (glomerular filtration rate (GFR)) are frequently used in the Swedish health care. GFR is usually estimated based on plasma creatinine concentration, but plasma cystatin C concentration, creatinine clearance, iohexol clearance, and (51)Cr-EDTA clearance are also used. These markers are all part of the daily patient care, but there is little specific informat...
