You will have to sit comfortably on the chair, and a healthcare provider will check your arms for an easily accessible vein.

You can expect the experience the following during the blood test or a blood draw: What should I expect during my Blood Urea Nitrogen (BUN) test? Usually, the samples are sent to a lab where a medical laboratory scientist prepares the samples and performs the tests on analysers or manually. Who performs a Blood Urea Nitrogen (BUN) test?Ī healthcare provider, who is also called a phlebotomist, usually performs blood draws, including those for blood urea nitrogen tests, but any healthcare provider trained in drawing blood can perform this task. Are Preparations Needed for the Blood Urea Nitrogen (BUN) Test? If you have previously had an abnormal BUN test report or you have a known kidney problem, repeat testing at regular intervals might be appropriate in order to monitor your situation and current kidney function. The doctor might also order the screening tests with a BUN measurement during routine medical exams. Your physician may recommend screening these tests, including a BUN measurement, if you have any risk factors for kidney disease, such as a family history of kidney problems or related issues, diabetes, or cardiovascular issues like high blood pressure. In addition, these test panels with BUN may be used to help with a diagnosis when you have general symptoms or are being evaluated in an emergency room or an urgent care centre. These tests may involve 8 and 14 measurements, respectively, and they provide insight into the multiple bodily systems, including the kidney function.Ī panel of these tests with a BUN measurement included may be appropriate if you have any symptoms of kidney disease. Who should get a Blood Urea Nitrogen (BUN) test?īlood urea nitrogen (BUN) is most commonly analysed as a part of the basic or comprehensive metabolic panel. The BUN test is done along with a creatinine test to evaluate kidney function, diagnose kidney disease, and monitor patients undergoing treatment for kidney disease. If it is due to liver damage or disease, there is less production of urea, and the concentration of BUN will fall.

If the liver produces urea in increased amounts or in case there is any problem in the functioning of the kidneys, there may be difficulty in filtering out the waste products from the blood, which will lead to a rise in urea concentrations in the blood. In the case of kidney or liver disease, there will be a change in the amount of urea present in the blood. This is a continuous process, a small amount of urea nitrogen always remains in the blood. Here, it is filtered out of the blood and then it is released into the urine. The liver releases urea into the blood, which is then carried to the kidneys. Usually, both ammonia and urea have nitrogen as the main component. It leads to the production of ammonia, which is further converted into urea. It is formed when the protein is metabolised into the amino acids. This urea is a waste product that is formed in the liver. What does a Blood Urea Nitrogen (BUN) test measure?īlood Urea Nitrogen test analyses the amount of urea nitrogen in the blood. There is only one parameter: blood urea nitrogen. What are the test parameters included in the Blood Urea Nitrogen (BUN) test? The other names are Urea nitrogen test and serum BUN. What are the other names for the Blood Urea Nitrogen (BUN) test? And having too much urea nitrogen in the bloodstream can be a sign of kidney or liver problems. BUN levels tend to increase when the kidneys or liver are damaged or malfunctioning. Normally, the kidneys filter out the waste and urinating removes it from the body. Urea nitrogen is a waste product that is created by the liver when the body breaks down the proteins. It does so by analysing the amount of urea nitrogen in the blood. What is a Blood Urea Nitrogen (BUN) test?Ī blood urea nitrogen (BUN) test is used to evaluate how well your kidneys are functioning.
