High BUN indicates increased protein breakdown, which is associated with decreased immune function. A study shows that patients with elevated BUN (> 20 mg/dl) have an increased risk of infection (R). High BUN is associated with increased mortality in critically ill patients (R, R, R, R).
BUN is an indication of renal (kidney) health. The normal range is 1.8-7.1 mmol/L or 6â20 mg/dL. Blood urea nitrogen levels can also help identify damage to body systems and diseases of the digestive, circulatory, and respiratory systems. The main causes of an increase in BUN are: high protein diet, decrease in glomerular filtration rate (GFR) (suggestive of renal failure) and in blood volume (hypovolemia), congestive heart failure, gastrointestinal hemorrhage, fever, and increased catabolism.
