Glomerular Filtration Rate (GFR)

GFR – glomerular filtration rate is the best test to measure your level of kidney function and determine your stage of kidney disease. Your doctor can calculate it from the results of your blood creatinine test, your age, body size and gender. Your GFR tells your doctor your stage of kidney disease and helps the doctor plan your treatment. If your GFR number is low, your kidneys are not working as well as they should. The earlier kidney disease is detected, the better the chance of slowing or stopping its progression.

GFR level varies among age groups.

Age (years) Average estimated GFR
20–29 116
30–39 107
40–49 99
50–59 93
60–69 85
70+ 75

Doctors determine the severity of chronic kidney disease with a staging system that uses GFR:
