A BUN test measures the amount of urea nitrogen that's in your blood. Your liver produces ammonia — which contains nitrogen — after it breaks down proteins used by your body's cells.

Understanding Your Lab Values Blood Urea Nitrogen (BUN): Urea nitrogen is a normal waste product in your blood that comes from the breakdown of protein from the foods you eat and from your body metabolism. It is normally removed from your blood by your kidneys, but when kidney function slows down, the BUN level rises. BUN can also rise if you eat more protein, and it can fall if you eat less protein. Urine Protein: When your kidneys are damaged, protein leaks into your urine. A simple test can be done to detect protein in your urine. Persistent protein in the urine is an early sign of chronic kidney disease.

This causes high levels of urea in the blood.
