WebThe current variability in serum creatinine measurement renders all estimating equations for GFR, including the MDRD study equation, less accurate in the normal and slightly elevated range of serum creatinine concentrations [133 µmol/L (1.5 mg/dL)], which is the relevant range for detecting chronic kidney disease (60 mL/min/1.73 m 2). WebIn healthy young adults, a normal eGFR is around 80-120 ml/min/1.73 m 2. This is very convenient, because it means that estimates of GFR are the same as percentages of normal – for instance, a person with a GFR of 30 ml/min/1.73 m 2 has 30% of normal kidney function for a person of their size. thomas helbing ray sono
