A microalbumin test is a laboratory test that measures the amount of a protein called microalbumin in a urine sample. Microalbumin is a type of protein that is normally found in small amounts in the urine. It is produced by the kidneys and is an early indicator of kidney damage or disease. A microalbumin test is often used to detect kidney damage in people with diabetes, high blood pressure, or other conditions that can affect the kidneys. The test is typically done by collecting a urine sample and sending it to a laboratory for analysis. Elevated levels of microalbumin in the urine may indicate that the kidneys are not functioning properly and may need further evaluation and treatment.
