Remarks

The equation used for calculating CKD-EPI eGFR is the 2009 CKD-EPI eGFR equation (Levey AS et al. Ann Intern Med 2009;150:604-12). This equation is only valid for individuals aged 18 years and above.

Gender	Serum Creatinine (µmol/L)	2009 CKD-EPI eGFR equation
Female	≤ 62	144 x (Creatinine/62)^-0.329 x (0.993)^Age
Female	> 62	144 x (Creatinine/62)^-1.209x (0.993)^Age
Male	≤ 80	141 x (Creatinine/80)^-0.411 x (0.993)^Age
Male	> 80	141 x (Creatinine/80)^-1.209 x (0.993)^Age
