Your doctor can determine how well your kidneys are working by calculating your glomerular filtration rate (GFR).
To calculate your GFR, your doctor will use a formula that combines your:
The process in which your kidneys filter your blood to eliminate surplus waste and fluids
The GFR determines how well blood is filtered by your kidneys; this is one way to measure your kidney function. Your doctor will use your GFR to establish the stage of your kidney disease and guide treatment decisions.
|Stage||Description||GFR||What this means|
|1||Kidney damage with normal or high GFR||90 or above||
|2||Kidney damage with mildly low GFR||60–89||
|3||Kidney damage with moderately low GFR||30–59||
|4||Kidney damage with severely low GFR||15–29||
|5||Kidney failure||Below 15||
Please remember that every chronic kidney disease patient is unique—age, medical condition, physical condition and lifestyle choices. All these factors must be taken into consideration before determining a treatment option according to your CKD stage. You and your doctor will come up with the best course of action for your individual situation.
