The BUN (Blood Urea Nitrogen) test measures the amount of urea nitrogen in the blood, which is a waste product formed in the liver when protein is metabolized. Urea is normally excreted by the kidneys, so this test provides important information about kidney function and overall metabolic health. Elevated BUN levels may indicate kidney disease, dehydration, high-protein diet, or heart failure, while low levels can occur in malnutrition, liver disease, or overhydration. It is commonly ordered alongside creatinine to assess renal function, guide treatment, and monitor patients with chronic conditions. Regular monitoring helps detect early kidney impairment and evaluate the effectiveness of therapies, making it a critical marker for clinicians in diagnosing and managing renal and metabolic disorders. The test requires a simple blood sample, and results are influenced by diet, medications, and hydration status.
