Prerenal proteinuria is caused by the presence of proteins in the plasma that are filtered through a normal glomerulus with normal permeability to macromolecules (i.e., permselectivity). (vin.com)
Postrenal proteinuria is due to plasma proteins from hemorrhage or inflammation in the urinary tract (kidneys, ureters, bladder, urethra, and/or accessory sex glands). (vin.com)
