Additional Notes:

Reference Intervals (mL/min/1.73m²):

eGFR is automatically calculated from serum creatinine, sex and age, using the CKD-EPI formula as of 15-06-2014 and as per Kidney Health Australia guidelines. Refer to http://www.kidney.org.au/healthprofessionals/gfrcalculatorckdepi/tabid/803/default.aspx

It is not calculated on patients under 18 years of age.

eGFR between 60 and 90 mL/min/1.73m2 indicates mild reduction in GFR but is likely to be normal for elderly patients.

eGFR between 30 and 59 mL/min/1.73m2 indicates moderate decrease in GFR.

eGFR between 15 and 29 mL/min/1.73m2 indicates severe decrease in GFR.

eGFR less than 15 mL/min/1.73m² is consistent with end-stage kidney disease.
