Full Form of BUN
What is BUN?
Blood Urea Nitrogen (BUN) is a medical laboratory test that measures the amount of nitrogen in the blood that comes from the waste product urea. Urea is produced by the liver as a byproduct of protein metabolism and is normally filtered out of the blood by the kidneys and excreted in urine. In India, BUN is a standard component of renal function panels, used to assess kidney health and diagnose conditions such as acute or chronic kidney disease, dehydration, urinary tract obstruction, or gastrointestinal bleeding. It is commonly ordered alongside serum creatinine and electrolytes to evaluate overall kidney function, particularly in hospitals, diagnostic centres, and routine health check-ups. The test is widely available and affordable across Indian cities and rural areas, often included in preventive health packages. For medical students and aspirants of NEET PG, AIIMS, and other entrance exams, understanding BUN levels, their normal range (typically 7–20 mg/dL), and interpretation in disease states is crucial. Elevated BUN can indicate impaired kidney function, while low BUN may suggest liver disease or overhydration. The test is also used to monitor patients on dialysis or those with critical illnesses. Overall, BUN remains a fundamental, cost-effective tool for early detection and management of renal disorders in the Indian healthcare system.
