Why is your GFR important?

GFR is a measure of your percent kidney function. Knowing your GFR helps you learn how much kidney function you have so you can better protect your health. Using your GFR number, look below to see what stage of kidney disease you have. There are five stages of kidney disease. Stage one indicates a small amount of damage, and stage five happens when your kidneys have failed. Your stage of kidney disease depends on your GFR number.
