Albumin is a very important plasma protein. Normally, albumin has a large molecular weight and cannot pass through the basement membrane of the glomerulus. So a healthy person's urine contains very low levels of albumin. Urine albumin does not exceed 20 mg, so it is called "urine microalbumin". Injury and penetrating changes of the glomerular basement membrane. Any pathology that may increase the permeability of the glomerular basement membrane may result in the excretion of albumin. This is when albumin enters your urine, where the concentration of albumin increases.
