BUN (Blood Urea Nitrogen) View All. Blood urea nitrogen - BUN - is a blood test performed as a marker of kidney function. It is part of the basic metabolic panel done for health screening. It is also used to monitor the progression of kidney failure. BUN is produced by the breakdown of protein and usually cleared from the blood by the kidneys.

Medical Dictionary Why It Is Done. A blood urea nitrogen (BUN) test is done to: See if your kidneys are working normally. See if your kidney disease is getting worse. See if treatment of your kidney disease is working. Check for severe dehydration. Dehydration generally causes BUN levels to rise more than creatinine levels.

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.

Blood urea nitrogen Blood urea nitrogen (BUN) is a medical test that measures the amount of urea nitrogen found in blood. The liver produces urea in the urea cycle as a waste product of the digestion of protein. Normal human adult blood should contain between 6 and 20 mg of urea nitrogen per 100 ml (6–20 mg/dL) of blood.

How a nephrologist assesses your kidney function BUN or blood urea nitrogen is a term to describe the breakdown products of protein in your body. This value is affected by many things including: 1  blood loss through the gastrointestinal tract. 2  the use of steroids for patients with COPD and emphysema. 3  the level of hydration in the body.

Blood Test Interpretation If interpreted correctly by someone with an understanding of what to look for, blood tests can reveal data that often times gets overlooked. For example, a typical, “normal”, “conventional” reference range for BUN (Blood, Urea, Nitrogen) is anywhere between 7-25. This range is far from accurate. A person with a BUN level of 7 will have a variety of health issues. Someone with that low of a BUN level is extremely under-nourishing themselves.

Blood Urea Nitrogen (BUN) Urea is a waste product formed in the liver when protein is metabolized. Urea is released by the liver into the blood and is carried to the kidneys, where it is filtered out of the blood and released into the urine.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.

The kidneys even produce hormones that manage red blood cell production and regulate blood pressure. A blood urea nitrogen (BUN) test is used to determine how well your kidneys are working. It does this by measuring the amount of urea nitrogen in the blood. Urea nitrogen is a waste product that’s created in the liver when the body breaks down proteins. Normally, the kidneys filter out this waste, and urinating removes it from the body. BUN levels tend to increase when the kidneys or liver are damaged.

Normal BUN & Creatinine Levels The BUN measures the amount of urea nitrogen in the blood. Urea is formed in the liver as the end product of protein metabolism and digestion. The urea is deposited in the blood and transported to the kidneys for excretion. The BUN serves as an index of the function of the liver and the kidneys.
