What is the BUN range for adults?

The normal range for Blood Urea Nitrogen (BUN) levels in adults is typically considered to be between 10 and 20 mg/dL. BUN is a measure of the nitrogen in the blood that comes from the waste product urea, which is formed in the liver from the breakdown of proteins. An elevated BUN level can indicate a variety of conditions, including kidney dysfunction, dehydration, or high protein intake.

The correct range of 10-20 mg/dL is established based on standard laboratory references. Values outside this range can signal different health issues but might not be clinically significant unless coupled with other lab findings or symptoms. Understanding these reference ranges helps in interpreting lab results and assessing kidney function as part of a broader health evaluation.
