A normal UN (urea nitrogen) blood test, often referred to as blood urea nitrogen (BUN), measures the amount of nitrogen in the blood that comes from urea, a waste product formed from protein metabolism. Typical reference ranges for BUN levels are generally between 7 and 20 mg/dL, but these values can vary slightly depending on the laboratory. Elevated BUN levels may indicate kidney dysfunction, dehydration, or high protein intake, while low levels could suggest liver disease or malnutrition. Always consult a healthcare professional for interpretation of test results.
