BUN (Blood Urea Nitrogen)

Dr. Kennedy
BUN (blood urea nitrogen) is a measure of the urea level in blood. Urea is cleared by the kidneys and diseases which compromise the function of the kidneys will frequently lead to increased blood levels. The blood BUN level can also rise in patients who are dehydrated and in people who have recently engaged in heavy exercise.
