eGFR by Age Calculator: Compare Normal Kidney Function Ranges
See how an eGFR result compares with typical age-related values without treating an age average as a diagnosis.
eGFR by Age Interpreter
Age-based averages are population estimates, not diagnostic cutoffs. CKD staging uses eGFR ranges and evidence of kidney damage, not age alone.
Does eGFR normally decline with age?
Average eGFR tends to decline with age, but healthy values vary widely. A lower result can be important in a younger adult and age-appropriate in an older adult. Repeat testing and urine albumin are essential context.
