Urinary microalbumin test is used to measure the minute amount of albumin present in your urine. This test may help to diagnose kidney dysfunction or kidney damage. It also helps in finding out whether diabetes has affected your kidneys.
What is Albumin?
Albumin is a kind of protein required for tissue growth and healing. It is usually present in the blood. Kidneys are responsible for removing waste products in blood and regulating water fluid levels in the body. It restores nutrients and proteins required for the body especially albumin. During kidney dysfunction or kidney damage albumin is not restored and leaked into the urine. A significant amount of albumin in urine may indicate kidney damage. The presence of albumin in urine is called albuminuria.
