Albumin is one of the important plasma proteins. Under normal circumstances, the molecular weight of albumin is large and it cannot pass through the basement membrane of the glomerulus. Therefore, there is only a very low concentration of albumin in the urine of healthy people, specifically up to 20mg of urinary albumin per liter. In disease, damage to the glomerular basement membrane changes the permeability. Any lesion that increases the permeability of the glomerular basement membrane can lead to the excretion of albumin. At this time albumin into the urine, urine albumin concentration is continuously increased.
