An albumin-creatinine ratio test compares the amounts of albumin and creatinine in your urine.
Albumin (say "al-BYOO-mun") is normally found in the blood. When the kidneys are damaged, small amounts of albumin (microalbumin) leak into the urine.
Creatinine (say "kree-AT-uh-neen") is a waste product found in urine.
This test helps your doctor see how well your kidneys are working. It is done most often to check the kidneys in people with diabetes. It may also be done to check people with high blood pressure, heart failure, and cirrhosis.
One-time urine collection
Urine collection over time
You collect your urine for a period of time, such as over 4 or 24 hours.
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.
