What Does a High BUN Count Mean? Quick Answer. A high BUN count usually indicates that the kidneys are not working properly, but there are other issues that can cause high results, as stated by Mayo Clinic. Some other causes for a high BUN count are a high protein diet, dehydration and congestive heart failure. BUN is an acronym for blood urea nitrogen, and results can vary depending on an individual's age as well as the lab that processes the test, as explained by Mayo Clinic. Shock, severe burns and some medications, such as certain antibiotics, can also cause higher-than-normal BUN results. Doctors consider a BUN test a standard type of blood test and use it to measure the amount of urea nitrogen in the blood. The liver breaks down proteins in the body, which causes ammonia production, according to Mayo Clinic.

BUN (Blood Urea Nitrogen) Test In some cases, the location for the blood draw will be different. The BUN test is conducted to check the functioning of the kidneys. The kidneys are a pair of organs that are tasked with the function of cleaning the blood. Blood is used as a transport medium for nutrients and hormones to various parts of the body. Blood is also used to remove wastes from these parts of the body.

Blood Urea Nitrogen (BUN) The creatinine blood test is used to assess kidney function. It is frequently ordered along with a BUN (blood urea nitrogen) test or as part of a basic or comprehensive metabolic panel (BMP or CMP), groups of tests that are performed to evaluate the function of the body's major organs.he remaining waste forms urine. If the creatinine and BUN tests are found to be abnormal or if someone has an underlying disease that is known to affect the kidneys, such as diabetes or high blood pressure, then creatinine and BUN tests may be used to monitor for kidney dysfunction and the effectiveness of treatment.

Overview Blood urea nitrogen (BUN) test. Overview. A common blood test, the blood urea nitrogen (BUN) test reveals important information about how well your kidneys and liver are working. A BUN test measures the amount of urea nitrogen that's in your blood. Your liver produces ammonia — which contains nitrogen — after it breaks down proteins used by your body's cells. The nitrogen combines with other elements, such as carbon, hydrogen and oxygen, to form urea, which is a chemical waste product. The urea travels from your liver to your kidneys through your bloodstream.

What Does a High BUN Count Mean? This is what forms urea, which travels through the bloodstream from the liver to the kidneys. Kidneys that are functioning normally remove urea from the blood, and it leaves the body through the urine. A BUN test measures an individual's level of kidney function by providing an evaluation of urea nitrogen levels.

What Is a Blood Urea Nitrogen Test? Urea nitrogen is a normal waste product that your body creates after you eat. Your liver breaks down the proteins in your food -- and while it does that, it creates blood urea nitrogen, also known as BUN. Your liver releases the substance into the blood, and it eventually ends up in your kidneys. When your kidneys are healthy, they remove the BUN, usually leaving a small amount of it in the blood.
