Albumin is a protein. Albuminuria (Al-byoo-mih-noo-ree-uh) is having too much protein in the urine. This is sometimes referred to as “microalbuminuria” which indicates a slightly high level of protein in the urine. Overt proteinuria or “macroalbuminuria” indicates more than 300mg of albumin in the urine per day.
