What is the BUN Test?
The Blood Urea Nitrogen (BUN) test measures the amount of nitrogen in your blood that comes from urea, a waste product formed when the liver breaks down protein. Healthy kidneys remove urea from the blood.
BUN is usually checked together with creatinine. The two values — and the ratio between them — help doctors tell apart kidney problems from dehydration and other causes.
What it measures: Urea nitrogen in the blood, reflecting kidney filtration, hydration and protein breakdown.
