What is eGFR?
Estimated glomerular filtration rate (eGFR) is the one of the ways to measure the level of an individual’s kidney function and help determine the individual’s stage of kidney disease. The National Institutes of Diabetes & Digestive & Kidney Diseases, the National Kidney Foundation and the American Society of Nephrology recommend the Modification of Diet in Renal Disease (MDRD) study equation in order to calculate eGFR from serum creatinine levels. The MDRD study equation is as follows: is the serum creatinine concentration in mg/dL. The results are expressed relative to a standard body surface area of 1.73 m^2 to allow for different body sizes.
