Blood Urea Nitrogen details

What Blood Urea Nitrogen shows

Blood urea nitrogen (BUN) measures urea, a waste product created when your liver breaks down protein, which is then filtered out of your blood by the kidneys. It's one of the core markers used, together with creatinine, to assess kidney function โ€” elevated BUN can indicate reduced kidney filtering ability, but it can also rise with dehydration, a high-protein diet, gastrointestinal bleeding, or certain medications, even when the kidneys themselves are working normally. Because BUN is affected by more non-kidney factors than creatinine, it's rarely interpreted alone; the BUN/creatinine ratio is often calculated specifically to help distinguish a true kidney problem from causes like dehydration.
