Definition of Microalbuminuria test:

The microalbuminuria test looks for small quantities of protein called albumin in a urine sample.

See also: Urine albumin

How the test is performed:

A small sample of urine needs to be collected.

Because the amount of water in urine can vary, it can affect the concentration of albumin. For this reason, the amount of creatinine is also measured. The result is reported as the ratio of albumin to creatinine.

If albumin is found, some health care providers will repeat the test on a 24-hour urine sample.

How to prepare for the test:

No special preparation is necessary for this test.

How the test will feel:

The test involves only normal urination. There is no discomfort.

Why the test is performed:

This test is most often done to detect diabetic nephropathy in a person who has had diabetes for several years.

Detectable levels of the protein albumin in the urine signal the beginning of a condition called microalbuminuria, and are typical in disorders such as diabetic nephropathy. The test may show whether you are at risk for developing kidney disease.

The American Diabetes Association recommends that people with diabetes receive an annual microalbuminuria urine test. Patients should also have their blood creatinine tested at least once a year.
