Clinical Significance
Daily urine output is 1-2 liters which contains only 40-80 mg of protein. The ability of the kidneys to filter 2,000 liters of blood per day without loss of large amounts of protein is one of the most important characteristics of a normal kidney. Normal function of both the glomerulus and tubules are required to achieve this. Damage to either (or both) tends to result in protein excretion. Proteinuria occurs in nearly all diseases of the kidney and results from one or more mechanisms:
1. Damage to glomerular basement membrane which allows increased amounts of protein to enter the filtrate.
2. Impaired reabsorption of filtered protein by the tubular cells.
3. Secretions or loss of protein from the tubular cells.
4. Filtration of an abnormal protein which is too small to be retained by glomerular membrane (eg. Bence-Jones proteinuria)
