The Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equation was developed as a follow-up to the MDRD equation in an attempt to be as accurate in describing renal function at lower GFR (less than 60 mL/min/1.73 m 2), but more accurate at a higher GFR.The CKD-EPI equation was developed and validated retrospectively in 8,254 patients from 10 studies. The National Kidney Foundation recommends using the CKD-EPI Creatinine Equation (2009) to estimate GFR. **The NIDDK presently recommends reporting estimated GFR values 1. The estimated glomerular filtration rate (eGFR) is used to screen for and detect early kidney damage, to help diagnose chronic kidney disease (CKD), and to monitor kidney status.. eGFR calculated using the Modification of Diet in Renal Disease (MDRD) Study equation or the CKD-EPI equation provides a more clinically useful measure of kidney function than serum* creatinine alone.
