The BUN test measures the amount of urea nitrogen in the blood, a waste product formed when the body breaks down protein. Urea nitrogen is filtered from the blood by the kidneys, making this test a useful indicator of kidney function.
This test is commonly used to assess kidney health, hydration status, and overall metabolic function. Abnormal BUN levels may be associated with kidney disease, dehydration, high protein intake, or certain medications. BUN is often ordered as part of a basic or comprehensive metabolic panel.
