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 or chronic kidney failure. It may also be done to check people with high blood pressure, heart failure, and cirrhosis.
If the container has a lid, remove the lid and set it down with the inner surface up.
After the urine has flowed for several seconds, place the collection container in the stream. Collect about 60 mL (2 fl oz) of this "midstream" urine without stopping the flow. Don't touch the rim of the container to your genital area.
How to collect timed urine You collect your urine for a period of time, such as over 4 or 24 hours. Your doctor will give you a large container that holds about 4 L (1 gal). You will use the container to collect your urine.
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.
