What are the stages of kidney disease?
Kidney disease has five stages. They are shown in the table below. Your doctor determines your stage of kidney disease based on the presence of kidney damage and your glomerular filtration rate (GFR), which is a measure of your level of kidney function. Your treatment is based on your stage of kidney disease. Speak to your doctor if you have any questions about your treatment or your stage of kidney disease.
The 5 Stages of Kidney Disease Spectrum
Focus: Healthy diet, blood pressure control.
Focus: Glucose control & routine monitoring.
Focus: Nephrologist care & kidney nutrition.
Focus: Specialized planning & care coordination.
Focus: Active therapy (dialysis or transplant).
DETAILED STAGES OF KIDNEY DISEASE TABLE
| Stage | Description | Glomerular Filtration Rate (GFR)* |
|---|---|---|
| 1 | Kidney damage (e.g., protein in the urine) with normal GFR | 90 or above |
| 2 | Kidney damage with mild decrease in GFR | 60 to 89 |
| 3 | Moderate decrease in GFR | 30 to 59 |
| 4 | Severe reduction in GFR | 15 to 29 |
| 5 | Kidney failure | Less than 15 |
*Your GFR number tells your doctor how much kidney function you have. As chronic kidney disease progresses, your GFR number goes down.
What happens if my test results show I already have kidney disease?
More tests may be done to help understand what caused your kidney disease. This can help plan your treatment. You may also be asked to see a specialist. Below are examples of tests that might be done:
- An ultrasound or CT scan to get a picture of your kidneys and urinary system. These pictures show the size of your kidneys and whether they are too large or too small. They also show if there are any tumors, kidney stones, or cysts.
- A biopsy to remove a small piece of kidney tissue for evaluation. The sample is studied under a microscope to: See what kind of kidney damage has happened; See how much damage has happened.
- Plan treatment.
