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.

What do normal BUN levels indicate? What do normal BUN levels indicate? A: Normal BUN, blood urea nitrogen, levels indicate proper functioning of the liver and kidneys, according to Mayo Clinic. The liver produces nitrogen when it breaks down protein, which along with other chemicals forms urea. Urea enters the bloodstream and moves to the kidneys, where it is filtered from the blood.

Blood urea nitrogen BUN is an indication of renal (kidney) health. The normal range is 1.8-7.1 mmol/L or 6–20 mg/dL. Blood urea nitrogen levels can also help identify damage to body systems and diseases of the digestive, circulatory, and respiratory systems. The main causes of an increase in BUN are: high protein diet, decrease in glomerular filtration rate (GFR) (suggestive of renal failure) and in blood volume (hypovolemia), congestive heart failure, gastrointestinal hemorrhage, fever, and increased catabolism.

Blood Urea Nitrogen A blood urea nitrogen (BUN) test measures the amount of urea nitrogen found in your blood. BUN levels help your doctor see how well your kidneys are working. The test may be used along with other measurements to help diagnose a kidney disorder or find out how well your treatment for kidney disease is working.our doctor may also check the creatinine levels in your blood. On its own, the BUN level does little to tell your doctor about your kidney, or renal, function. But when it is measured along with creatinine levels, your doctor can look at how these two levels compare to help find out your kidney function.

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.

Blood Urea Nitrogen Even if your test results are different from the normal value, you may not have a problem. To learn what the results mean for you, talk with your health care provider. The normal BUN level is between 7 and 21 milligrams per deciliter (mg/dL). Unless this level is greater than 60 mg/dL, though, it doesn't help your doctor measure your kidney health.

Blood Urea Nitrogen (BUN) What other tests are used with the blood urea nitrogen test to check how my kidneys are functioning? BUN and creatinine are the primary tests used to check how well the kidneys are able to filter waste products from your blood. Your healthcare provider may also order a renal panel or electrolyte tests, such as sodium and potassium, or calcium to help understand how your kidneys are functioning.

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. 1  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.

- A blood urea nitrogen (BUN) test checks kidney function by measuring how much urea nitrogen is in your blood.Urea nitrogen is a waste product from the breakdown of protein in the body.ormally, this waste is filtered by the kidneys and leaves the body through urine. Too much or too little urea nitrogen in the blood could signify kidney problems. The BUN test is frequently done along with other tests to diagnose or monitor kidney diseases.

Creatinine and Creatinine Clearance  [en EspaÃ±ol] Blood urea nitrogen-to-creatinine ratio (BUN:creatinine) The BUN test measures the amount of urea in your blood. Urea is a waste product made when protein is broken down in your body. Urea is made in the liver and passed out of your body in the urine. The levels of blood creatinine and blood urea nitrogen (BUN) can be used to find the BUN-to-creatinine ratio. This ratio can help your doctor check for problems, such as dehydration, that may cause abnormal BUN and creatinine levels.

In medical terminology, what does BUN level mean? Rating Newest Oldest. Best Answer: BUN stands for Blood Urea Nitrogen. It is a measure of kidney function. The blood urea nitrogen (BUN) test is a test of how well your kidneys are working. It measures the amount of nitrogen in your blood. The nitrogen is present in a chemical called urea. Urea is a waste product produced as your body digests protein. Urea is carried by the blood to the kidneys, which filter the urea out of the blood and into the urine. BUN is usually measured to see how well your kidneys are working. Kidney disease often makes it hard for the kidneys to filter as much urea as they should. This causes high levels of urea in the blood.

- Blood Urea Nitrogen. A blood urea nitrogen (BUN) test measures the amount of nitrogen in your blood that comes from the waste product urea. Urea is made when protein is broken down in your body. Urea is made in the liver and passed out of your body in the urine. A BUN test is done to see how well your kidneys are working. If your kidneys are not able to remove urea from the blood normally, your BUN level rises. Heart failure, dehydration, or a diet high in protein can also make your BUN level higher.

BUN 26: What does it mean? In general, the normal BUN level for healthy individuals is 7-20 mg/dL (2.5 to 7.1 mmol/L) in adults, and 5-18 mg/dL in children. But normal ranges may vary, depending on the reference range used by the lab, and your age. Infants have lower levels than other people do.

- In the United States, blood urea nitrogen (BUN) is measured in mg/dL. To convert BUN to a concentration in mmol/L (SI units), multiply by 0.357 ([10 dL/1 L]/[28 mg of N/mmol of urea] = 0.357).

Overview Blood urea nitrogen (BUN) test. Results. Results of the blood urea nitrogen test are measured in milligrams per deciliter (mg/dL) in the United States and in millimoles per liter (mmol/L) internationally. In general, around 7 to 20 mg/dL (2.5 to 7.1 mmol/L) is considered normal. But normal ranges may vary, depending on the reference range used by the lab, and your age.

What Does a High BUN Count Mean? 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.
