MDRD GFR Equation
Estimates glomerular filtration rate based on creatinine and patient characteristics.
IMPORTANT
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.
INSTRUCTIONS
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.
