Proteinuria

Too many proteins in urine can be an indication of proteinuria. Healthy kidneys block the passage of proteins from the blood to urine through kidney filters known as glomeruli. Glomerulonephritis occurs with inflamation of glomeruli. The cause of the inflamation can be a number of conditions including diabetes, hypertension and infections from both bacterial and viral sources.

Blood tests and ultrasound can be helpful diagnostic tools in locating the cause of kidney problems that lead to proteinuria. This site furnishes further information on the topic.
