What is the normal range for BUN levels?

The normal range for Blood Urea Nitrogen (BUN) levels is typically between 8 and 30 mg/dL. This range reflects the concentration of urea nitrogen in the blood, which is a byproduct of protein metabolism. BUN levels can provide valuable information about a person's kidney function and hydration status. Levels lower than this range may indicate liver disease or malnutrition, while levels higher than this range can suggest renal impairment, dehydration, or excessive protein intake. Understanding the normal range is crucial for interpreting laboratory results in the context of a patient's overall health and any potential underlying conditions.
