Great question! eGFR less than 90 cc/min is stage 2 CKD by kidney website but it does not specify the age. Kidney function is naturally declining when people get older so if you have eGFR of 62 cc/min at 62 years old and there is no evidence of kidney disease such as abnormal kidney ultrasound/urine test, your function is normal. Quest's reference range shouldn't apply to people younger than 60.

Normal eGFR should be greater than 90. The calculation takes age and sex into account. Visit this site for information: https://www.kidney.org/atoz/content/gfr
