What is the currently recommended method to estimate GFR?
The National Kidney Disease Education Program (NKDEP) of the National Institute of Diabetes, Digestive and Kidney Diseases (NIDDK), National Kidney Foundation (NKF) and American Society of Nephrology (ASN) recommend estimating GFR from serum creatinine. Two commonly used equations are the MDRD Study equation and Cockcroft and Gault equation. Both equations use serum creatinine in combination with age, sex, weight or race to estimate GFR and therefore improve upon several of the limitations with the use of serum creatinine alone.
