Diabetic status and the performances of creatinine- and cystatin C-based eGFR equations

The estimation of glomerular filtration rate (GFR) is one main tool to detect renal disease. The most used biomarker remains serum creatinine and the European Kidney Function Consortium (EKFCcrea) equation is the most validated in Europe. More recently, cystatin C, has been proposed. We studied the performances of the EKFC equations in a large cohort of subjects according to their diabetic status.
