Warning: In this page we talk about BUN levels.

It important to know if the values measured are the BUN levels used in the US and other countries or instead the values measured are the total urea used in Europe and around the world.

There are some circumstances to take into account about BUN normal ranges in the blood: Your doctor will study the results along with your medical record, screenings, physical condition, symptoms and any other relevant information about your situation. There may be also slight differences in the normal levels according to age, gender, race or ethnic origin, geographic region, diet, type of sample and other relevant status. These ranges depend on the makeup of the local population, the technologies used and the accuracy of the measurement. Once you get your BUN blood test results, you will head off to your doctor’s office, where you will discuss your results.Each laboratory must establish its own normal ranges for BUN in the blood. Once the blood has been drawn, a bandage will be placed on your arm, and your blood sample will be sent off to the laboratory. A sterile needle will be inserted into a vein in your arm after the area has been cleaned with an antiseptic. It is like any other blood test that you might have done back in the past as it requires only a small sample of blood to be taken from your body. How Is A BUN Test Being Performed?Ī BUN test is quite easily be performed. Other than that, no specific preparation is required. This is the time when you are required to inform your doctor about the over-the-counter and prescribed medications and even dietary supplements that you might have been taking since certain medications can influence the BUN levels in the blood. Of course, you will need to consult your doctor and inform yourself about the importance of the BUN test as a part of the preparation process. Lower than usual, BUN levels can be caused by liver disease and malnutrition, but the BUN test is not usually performed when forming a diagnosis for these health issues.Ī BUN blood test does not require any special preparation.

On the other hand, low BUN levels are not so common and usually do not turn the alarm for concern. Of course, other tests apart from the BUN blood test needs to be done in order to determine the right diagnosis. Other possible causes for high BUN levels are a recent heart attack, congestive heart failure, and even dehydration, among many others. When we see increased BUN levels in a BUN test, which is an indication that we are dealing with an impaired kidney function, the BUN blood test can be used to form a diagnosis of either acute or chronic kidney disease, kidney damage, or even kidney failure. Normal BUN values mean that our kidneys are functioning well as expected.īUN Test Results Interpretation What Does BUN Blood Test High Indicate? For children, from the age of 1 to 17 years old, it is considered that 7 to 20 mg/dL is a healthy value of BUN in the blood. The levels of BUN are measured in milligrams per deciliter (mg/dL).įor adult men, the normal BUN values fall between 8 to 24 mg/dL, whereas, for adult women, the normal values tend to fall between 6 and 21 mg/dL. In addition, different laboratories also tend to have slightly different normal values when it comes to measuring BUN through a blood test. The normal ranges of BUN are known to vary depending on the gender and the age of the individual.

Some medical conditions in which a BUN test often helps to form a proper diagnosis are:

The BUN test is also done in order to evaluate the effectiveness of dialysis treatment. It is a test that informs us of the condition of our kidneys and their ability to filter and later eliminate this waste as expected. A BUN blood test is a test that measures the levels of blood urea nitrogen (BUN) in the blood.
