Early kidney disease usually doesn’t have any symptoms. Testing is the only way to know how well your kidneys are working.
To check for kidney disease, health care providers use
If you have kidney disease, your health care provider will use the same two tests to help monitor your kidney disease and make sure your treatment plan is working.
Your health care provider will use a blood test to check your kidney function. The results of the test mean the following:
You can’t raise your GFR, but you can try to keep it from going lower. Learn more about what you can do to keep your kidneys healthy.
Creatinine. Creatinine is a waste product from the normal breakdown of muscles in your body. Your kidneys remove creatinine from your blood. Providers use the amount of creatinine in your blood to estimate your GFR. As kidney disease gets worse, the level of creatinine goes up.
If you are at risk for kidney disease, your provider may check your urine for albumin.
Albumin is a protein found in your blood. A healthy kidney doesn’t let albumin pass into the urine. A damaged kidney lets some albumin pass into the urine. The less albumin in your urine, the better. Having albumin in the urine is called albuminuria.
A health care provider can check for albumin in your urine in two ways:
Dipstick test for albumin. A provider uses a urine sample to look for albumin in your urine. You collect the urine sample in a container in a health care provider’s office or lab. For the test, a provider places a strip of chemically treated paper, called a dipstick, into the urine. The dipstick changes color if albumin is present in the urine.
Urine albumin-to-creatinine ratio (UACR). This test measures and compares the amount of albumin with the amount of creatinine in your urine sample. Providers use your UACR to estimate how much albumin would pass into your urine over 24 hours. A urine albumin result of
If you have albumin in your urine, your provider may want you to repeat the urine test one or two more times to confirm the results. Talk with your provider about what your specific numbers mean for you.
If you have kidney disease, measuring the albumin in your urine helps your provider know which treatment is best for you. A urine albumin level that stays the same or goes down may mean that treatments are working.
