MDRD GFR Equation
Estimates GFR in CKD patients using creatinine and patient characteristics.
This calculator includes inputs based on race, which may or may not provide better estimates, so we have decided to make race optional. See here for more on our approach to addressing race and bias on MDCalc.
For the same creatinine value, this calculator estimates a higher GFR for Black patients.
Only for chronic kidney disease (CKD); not accurate for acute renal failure. This calculator uses the 4-variable equation from Levey 2006, which relied on a standardized creatinine assay.

Andrew S. Levey, MD, is the chief of the nephrology division at Tufts Medical Center and the Dr. Gerald J. and Dorothy R. Friedman Professor at Tufts University School of Medicine. His clinical interests include chronic kidney disease (CKD), diabetic kidney disease, and systemic lupus erythematosus. Dr. Levey’s research focuses on laboratory measures to estimate kidney function, new therapies, and the development of clinical practice guidelines for CKD.
