The blood urea nitrogen or BUN is a blood test that measures the amount of urea nitrogen in the bloodstream. It reflects how well your kidneys are. When a person is dehydrated, false results might be obtained as BUN levels increase when blood is concentrated. Elevated BUN levels indicate dehydration, excessive protein intake and impaired renal function. Low BUN levels indicate over hydration, liver damage and malnutrition.

Blood Urea Nitrogen (BUN) The blood urea nitrogen (BUN) test is used to measure the nitrogen fraction of urea, the chief end product of protein metabolism. Formed in the liver from ammonia and excreted by the kidneys, urea constitutes 40% to 50% of the blood’s nonprotein nitrogen content. BUN level reflects protein intake and renal excretory capacity.
