Blood urea nitrogen (BUN) is a measure of the amount of nitrogen in your blood that comes from the waste product urea. Urea is produced in the liver as a byproduct of protein metabolism and is normally excreted by the kidneys.
-BUN is commonly used as one indicator of kidney function. Elevated BUN levels may suggest that the kidneys are not effectively clearing urea from the blood.
