A common blood test, the blood urea nitrogen (BUN) test reveals important information about how well your kidneys are working. A BUN test measures the amount of urea nitrogen that’s in your blood. When your kidneys are healthy, they remove the BUN, usually leaving a small amount of it in the blood. When your kidneys are not healthy, they have trouble removing BUN and leave more of it in your blood.
