Creatinine/Urea nitrogen
A BUN, or blood urea nitrogen test, measures the amount of urea nitrogen in your blood. Urea nitrogen is a waste product that forms as your body breaks down proteins. It's carried in your blood and then removed by your kidneys when you urinate (pee).
A BUN test is often part of a series of tests called a comprehensive metabolic panel (CMP). It can help diagnose or monitor kidney diseases.
