Blood urea levels are assessed using the Blood Urea Nitrogen (BUN) measurement. This occurs because the kidneys fail to filter out the wastes as they should and consequently there are high levels of urea and nitrogen in the blood and this is toxic for the body. Hi Quora User, Urea is produced when our liver breaks down proteins/amino acids, and ammonia. On the other hand, it seems that not all urea should be considered  waste. 3.
