eGFR is estimated GFR calculated by the abbreviated MDRD equation : 186 x (Creatinine/88.4)-1.154 x (Age)-0.203 x (0.742 if female) x (1.210 if black). If you have an eGFR value calculated by a local laboratory, use that. It is likely to be more accurate than this calculator, which cannot take into account local variations in creatinine measurements.
