Book a Test- BUN (Blood Urea Nitrogen)

Blood Urea Nitrogen (BUN) is a medical test that measures the level of urea nitrogen in the blood. Urea nitrogen is a waste product produced by the liver as it breaks down protein. The kidneys are responsible for filtering urea nitrogen out of the blood and excreting it in the urine. The BUN test is used to evaluate kidney function and to diagnose kidney disease or damage. A high BUN level can indicate that the kidneys are not functioning properly, leading to a buildup of waste products in the blood. This can be caused by a variety of factors, including kidney disease, dehydration, or blockages in the urinary tract. On the other hand, a low BUN level is generally not a cause for concern. The BUN test is often performed in conjunction with other tests, such as the creatinine test, to provide a comprehensive picture of kidney function.
