<unk>  is a term to describe a moderate increase in the level of urine albumin. It occurs when the kidney leaks small amounts of albumin into the urine, in other words, when an abnormally high permeability for albumin in the glomerulus of the kidney occurs. Normally, the kidneys filter albumin, so if albumin is found in the urine, then it is a marker of kidney disease. The term<unk>  is now discouraged by Kidney Disease Improving Global Outcomes and has been replaced by moderately increased albuminuria.
