An albumin urine test checks urine for a protein called albumin. This protein is normally found in the blood. When the kidneys are damaged, small amounts of albumin leak into the urine. This is called albuminuria. If the amount of albumin is very small, but still abnormal, it is called microalbuminuria.
You might give a urine sample for your doctor during a visit. Your doctor might also ask you for a one-time sample at home or over a specific period of time, such as over 4 hours or 24 hours. Your doctor will tell you what to do.
This test is done to check for albumin in the urine. It helps tell your doctor how well your kidneys are working. This test is done most often to check the kidneys in people with diabetes. Other conditions also cause albuminuria. These conditions include high blood pressure, heart failure, and cirrhosis.
The sooner your doctor knows you have kidney damage, the more your doctor can do to protect your kidneys.
You collect your urine for a period of time, such as over 4 or 24 hours.
Watch closely for changes in your health, and be sure to contact your doctor or nurse call line if you have any problems.
Follow-up care is a key part of your treatment and safety. Be sure to make and go to all appointments, and call your doctor or nurse call line if you are having problems. It's also a good idea to keep a list of the medicines you take. Ask your doctor when you can expect to have your test results.
