Microalbuminuria is a test that determines albumin level in the urine.

Albumin is a protein that is usually filtered by the kidneys but when the kidneys leak tiny amounts of protein into the urine, it is known as Microalbuminuria.  It can be a possible indication of dysfunction of the kidneys and a risk factor for cardiovascular disease.

High blood glucose levels can damage kidneys and therefore the risk of microalbuminuria is higher with diabetes and also hypertension. It should be evaluated every 6 months after the beginning of blood pressure medications and once a year for all patients.

The test can be done on a urine sample collected over 24 hours

 If the albumin level ranges from 30 to 300 mg then it is called microalbuminuria

If the test is done on a spot urine sample, results between 20-200 mcg is defined as microalbuminuria

The target should be to maintain the albumin level below 30 mcg.

The development of microalbuminuria can be prevented by keeping A1C in target range less than 7% and blood pressure below 130/80 mmHg. If your readings are above target, please consult the physician.
