eGFR

Test/Investigation

eGFR

Site(s) or Laboratory offering Test/Investigation

NNUH, QEH, JPUH

Units

mL/min/1.73m^2

Also Known as/Frequency of Test

Estimated glomerular filtration rate

Comments/Precautions

2009 CKD-EPI is the CKD equation that is used to calculate eGFR in adults.

Turnaround times (TAT) Urgent/Routine/GP or OPD

1 hour / 4 hour / by 8am next day

Reference intervals (adult unless stated)

>90 mL/min/1.73m^2. Use of estimated GFR requires that kidney function and creatinine production are stable. eGFR should therefore be used with caution in acutely ill or hospitalised patients who may exhibit rapidly changing kidney function and/or changes in muscle mass.
