About This Test

The Blood Urea Test measures the concentration of urea nitrogen, a waste product formed during protein metabolism, in the blood. Urea is normally excreted by the kidneys, so elevated blood urea nitrogen (BUN) indicates impaired kidney function, dehydration, or increased protein breakdown. It aids in diagnosing and monitoring kidney diseases, urinary tract obstructions, and assessing overall renal health. Low urea levels may be seen in liver disease or malnutrition. The blood test is often part of routine metabolic panels and is essential for planning treatments or dialysis in chronic kidney disease patients. Monitoring blood urea helps prevent complications associated with kidney dysfunction and guides fluid and dietary management.
