Webb1 jan. 2004 · The simplified MDRD formula provides a robust estimate of GFR relative to serum creatinine based on age, race and sex . This estimate could then be used to calculate the relative change in GFR in a given patient. The application of the MDRD equation to estimate baseline creatinine requires a simple table with age, race and gender. WebbOur reference formula was the simplified MDRD (Modification in Diet of Renal Disease) formula. Glomerular filtration rate (GFR) was also estimated using the Cockroft-Gault (CG) and CKD epidemiology collaboration (CKD-EPI) formulas.
