What is the normal BUN range?

The normal blood urea nitrogen (BUN) range is typically between 10 and 20 mg/dL. BUN is a lab test that measures the amount of nitrogen in the blood that comes from urea, which is a waste product formed in the liver from protein metabolism. The BUN level provides valuable information about kidney function and hydration status.

Levels within the range of 10 to 20 mg/dL are considered normal and indicate that the kidneys are functioning properly by effectively clearing urea from the bloodstream. Higher or lower levels may suggest various health issues, such as kidney impairment, dehydration, or even liver problems, but the normal range indicates that the kidneys are processing waste products adequately.

Understanding this normal range is critical in clinical settings to assess and monitor a patient's renal function and overall metabolic state.
