Blood urea nitrogen (BUN) test measures the amount of urea nitrogen in the blood. Increased levels of urea in the blood (uremia) is an indicator for poor elimination of urea from the body usually due to kidney damage. Increased BUN levels can be caused by kidney diseases, kidney stones, congestive heart failure, fever, and gastrointestinal bleedings. BUN levels can also be elevated in pregnant people and people whose diet consists mainly of protein.
