Why It Is Done

A microalbumin urine test is done to detect protein (albumin) in the urine, a condition called microalbuminuria, that means your kidneys have been damaged. Early detection may change treatment in an effort to preserve as much kidney function as possible.

Test Overview

A microalbumin test evaluates urine for the presence of a protein called albumin. Albumin is normally found in the blood and filtered by the kidneys. When the kidneys are working properly, albumin is not present in the urine. However, when the kidneys are damaged, small amounts of albumin leak into the urine. .
