A waste product of the kidneys which provides a measure of kidney function or dehydration. Increased levels of BUN in the blood may indicate early kidney damage.

Abbreviated BUN. A measure of the urea level in your blood. Urea is cleared by the kidney. Diseases that compromise the function of the kidney frequently lead to an increased BUN.

(yoo-REE-uh NY-truh-jen) a waste product in the blood from the breakdown of protein. The kidneys filter blood to remove urea. As kidney function decreases, the BUN levels increase.

Urea nitrogen is what forms when protein breaks down. A test can be done to measure the amount of urea nitrogen in the blood in order to check kidney function. Source: MedlinePlus

A blood test that helps measure kidney function.

Nitrogen in the blood that comes from urea (a substance formed by the breakdown of protein in the liver). The kidneys filter urea out of the blood and into the urine. A high level of urea nitrogen in the blood may be a sign of a kidney problem. Also called BUN and urea nitrogen.

a blood test that helps to measure kidney function; when the kidney is not working, the amount of nitrogen in the blood will rise

A waste product regularly removed by the kidneys and eliminated in the urine. Regular testing of the BUN level serves as an indicator of how well the kidney is functioning.
