The Blood Urea Nitrogen (BUN) test measures the amount of urea nitrogen present in the blood. Urea is a waste product formed in the liver during protein metabolism and is excreted by the kidneys. Abnormal BUN levels can indicate impaired kidney function, dehydration, liver disease, heart failure, or excessive protein intake. This test is commonly used to monitor kidney health, assess hydration status, and evaluate patients with chronic kidney disease or acute renal conditions.
