Ask the Doctor
Questions about kidney disease? Risk factors? Signs and symptoms? Are you concerned about yourself, a friend or family member? Ask Dr. Spry.
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. The earlier kidney disease is detected, the better the chance of slowing or stopping its progression.
Your GFR tells your doctor your stage of kidney disease and helps the doctor plan your treatment. Your doctor can calculate it from your blood creatinine, your age, body size and gender.
|Stage||Description||Glomerular Filtration Rate GFR)|
|At increased risk||Risk factors for kidney disease (e.g., diabetes, high blood pressure, family history, older age, ethnic group)||More than 90|
|1||Kidney damage (protein in the urine) and normal GFR||More than 90|
|2||Kidney damage and mild decrease in GFR||60 to 89|
|3||Moderate decrease in GFR||30 to 59|
|4||Severe decrease in GFR||15 to 29|
|5||Kidney failure (dialysis or kidney transplant needed)||Less than 15|
