How do you know?

Your doctor or clinic should check to see if you have any risk factors for chronic kidney disease. These include:

You should visit your doctor or clinic and get tested. Your checkup should include:

Checking your blood pressure
Having a simple test for protein in your urine. Protein is an important building block in your body. Any filtered protein is normally reabsorbed and kept in your body. When your kidneys are damaged, however, protein leaks into your urine. There are different tests to find protein in your urine. If you have two positive tests over several weeks, you are said to have persistent protein in your urine. This is a sign of chronic kidney disease.
Having a simple blood test for creatinine, a waste product that comes from muscle activity. Your kidneys normally remove creatinine from your blood. When your kidneys are damaged, however, your blood creatinine may build to a high level. The results of your blood creatinine test should be used to estimate your glomerular filtration rate, or GFR. Your GFR tells how much kidney function you have.

Most people do not have any severe symptoms until their kidney disease gets worse. However, you may:

Your doctor will want to pinpoint your diagnosis and check your kidney function to help plan your treatment. The doctor may do the following:

Calculate your Glomerular Filtration Rate (GFR), which is the best way to tell how much kidney function you have. You do not need to have another test to know your GFR. Your doctor can calculate it from your blood creatinine, your age, race, gender and other factors. Your GFR tells your doctor your stage of kidney disease and helps the doctor plan your treatment. (See chart "Stages of Chronic Kidney Disease.")
Perform an ultrasound or CT scan to get a picture of your kidneys and urinary tract. This tells your doctor whether your kidneys are too large or too small, whether you have a problem like a kidney stone or tumor and whether there are any problems in the structure of your kidneys and urinary tract.
Perform a kidney biopsy, which is done in some cases to check for a specific type of kidney disease, see how much kidney damage has occurred and help plan treatment. To do a biopsy, the doctor removes small pieces of kidney tissue and looks at them under a microscope.

Your doctor may also ask you to see a kidney specialist who will consult on your case and help manage your care.

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

Most likely. Early detection and treatment can often slow or stop chronic kidney disease. How well your treatment can achieve this goal depends on:

Your stage of chronic kidney disease when you start treatment. The earlier you start, the better you are likely to do.
How carefully you follow your treatment plan. Learn all you can about chronic kidney disease and its treatment, and make sure to follow all the steps of your treatment faithfully.
The cause of your kidney disease. Some kidney diseases are more difficult to control.
