MDRD GFR Equation

Estimates glomerular filtration rate based on creatinine and patient characteristics.

Only for chronic kidney disease (CKD), not accurate for acute renal failure. Please also note that a recent study indicates the MDRD may underestimate the actual GFR in healthy patients by up to 29%.

Calculations must be re-checked and should not be used alone to guide patient care nor should they substitute for clinical judgement. See our full disclaimer.
