6 GFR Equations - Estimating GFR in the Elderly
(With SI Units)

4 variable MDRD Equation, CKD-EPI Equation, CKD-EPI Cystatin C Equation (2012) and CKD-EPI Cystatin C-Creatinine Equation (2012), BIS 1 and BIS 2 Equations (with SI Units)
using standardized serum creatinine, age, race, gender and cystatin C

programmed by Stephen Z. Fadem, M.D., FACP, FASN
and Brian Rosenthal




NOTE: CKD-EPI GFR is only valid with creatinine methods are traceable to IDMS
years
Race
