Creatinine-Cystatin C Equation (CKD-EPI 2012) for Estimating GFR

Sex	Scr (mg/dL)	Scys (mg/L)	eGFR (mL/min/1.73 m²)
Women	≤0.7	≤0.8	130×(Scr/0.7)^-0.248×(Scys/0.8)^-0.375×0.995^Age
		>0.8	130×(Scr/0.7)^-0.248×(Scys/0.8)^-0.711×0.995^Age
	>0.7	≤0.8	130×(Scr/0.7)^-0.601×(Scys/0.8)^-0.375×0.995^Age
		>0.8	130×(Scr/0.7)^-0.601×(Scys/0.8)^-0.711×0.995^Age
Men	≤0.9	≤0.8	135×(Scr/0.9)^-0.207×(Scys/0.8)^-0.375×0.995^Age
		>0.8	135×(Scr/0.9)^-0.207×(Scys/0.8)^-0.711×0.995^Age
	>0.9	≤0.8	135×(Scr/0.9)^-0.601×(Scys/0.8)^-0.375×0.995^Age
		>0.8	135×(Scr/0.9)^-0.601×(Scys/0.8)^-0.711×0.995^Age

Scr, serum creatinine; Scys, serum cystatin C.
