Estimated GFR (eGFR) formulae in human patients

	Predicted clearance	Formula	Variable
Cockcroft‐gault	Creatinine clearance	[(140 ‐ age) × BW/f] × SCr	Age (yrs), BW; body weight (kg), SCr; serum creatinine (mg/L), f; factor 7.2 for males and 8.5 for females
MDRD	¹²⁵I‐Iothalamate clearance	170 × SCr^−0.999 × age^‐0.176 × 0.762 (if female) × 1.18 (if black) × SUN^−0.170 × alb^0.318	SCr; serum creatinine (mg/dL), age (yrs), SUN; serum urea nitrogen (mg/dL), alb; serum albumin (g/dL)
CKD‐EPI	¹²⁵I‐Iothalamate clearance	a × (SCr/b)^c × 0.993^age	a is a factor based on race and sex (black women ‐ 166, black men ‐ 163, white women ‐ 144, white men ‐ 141), b is a factor based on sex (women ‐ 0.7, men ‐ 0.9), c is a factor based on sex and SCr (μmol/L; women SCr < 62 ‐ −0.329, SCr > 62 ‐ −1.209, men SCr < 80 ‐ −0.411, SCr > 80 ‐ −1.209), age (yrs)
