Comments
The eGFR is calculated with the modified MDRD equation using the serum creatinine (traceable to IDMS calibration).
MDRD eGFR mL/min/1.73M2= 175 X (SCr, mg/dL)-1.154 X (Age) -0.203 X (0.742 if female) X (1.210 if African –American)
Reference Range: eGFR (ages 18-70): >60 mL/min/1.73M2

Reference Ranges:  Serum Creatinine mg/dL               (effective 5/22/2008)
