Kidney Function Gfr Normal Range. Therefore a persistently reduced gfr is a. In adults the normal egfr number is more than 90.
A gfr below 15 indicates that you need to start a treatment for kidney failure. Egfr declines with age even in people without kidney disease. In general a good gfr number is above 60 and a good creatinine number is below 1 2.
Your gfr number tells you how much kidney function you have as kidney disease gets worse the gfr number goes down.
A better way to measure kidney function is to estimate gfr with equations that use serum creatinine levels and some or all of the following variables. A gfr below 15 indicates that you need to start a treatment for kidney failure. Egfr declines with age even in people without kidney disease. See chart below for average estimated egfr based on age.
