What are the normal limits of BUN in mg/dL for adults?

The normal limits of Blood Urea Nitrogen (BUN) for adults typically range from 10 to 20 mg/dL. BUN is a waste product formed in the liver from protein metabolism and is excreted by the kidneys. Measuring BUN levels is a common practice to assess kidney function, hydration status, and the metabolic state of an individual.

While values can vary slightly based on the laboratory and the specific population being assessed, the range of 10 to 20 mg/dL is widely accepted in clinical practice. Levels outside this range can indicate various medical conditions. Elevated BUN can suggest renal impairment, dehydration, or high protein intake, while decreased levels may suggest liver failure or malnutrition. Understanding these normal limits is crucial for interpreting laboratory results and managing patient care effectively.
