Table 6. Recommended equations for GFR estimation.

2009 CKD-EPI EQUATION (adults ≥ 18 years)
Gender	Serum creatinine (µmol/L)	Equation (for patients ≥ 18 years)
Female	≤62	eGFR =144 x (creat / 62)-0.329x (0.993)age
Female	>62	eGFR =144 x (creat / 62)-1.209x (0.993) age
Male	≤80	eGFR =141 x (creat / 80)-0.411x (0.993) age
Male	>80	eGFR =141 x (creat / 80)-1.209x (0.993) age
For black race use a multiplier of 1.159
SCHWARTZ EQUATION (children <18 years)
GFR (mL/min/1.73 m2) = (36.2 × height) / creatinine (height in cm, serum creatinine in µmol/L)
