An abnormally high blood urea nitrogen (BUN) level may indicate damage to the kidneys and a decreased ability to properly remove nitrogenous waste from the blood in your urine.
Testing the urea in the blood indicates the ability to properly metabolize protein. If the level varies too high or low the doctor will ask for a BUN to check the kidneys.
Blood Urea NitrogenBlood Urea Nitrogen, a high level usually means impaired kidney function.it is the blood urea nitrogen. Elevated in dehydration, kidney problems and others things.BUN = Blood Urea NitrogenA 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. Liver disease or damage can lower your BUN level. A low BUN level can occur normally in the second or third trimester of pregnancy.
Urea is formed in the liver from excess proteins. Therefore, the blood that travels from the liver to the kidney via the heart has relatively high levels (but not unsafe levels) of urea. It is filtered completely in the kidneys, and passes out in the urine. Consequently, blood in the renal veins (ie. leaving the kidneys) should have no urea, as it is a toxin which, if allowed to accumulate in the body, can poison us.
the blood plasma carries waste products, including urea.
Urea. It is measured by the level of BUN (blood urea nitrogen).
Too much or too little urea nitrogen in the blood could signify kidney problems.
BUN, why is the cumbersome term, why not just serum urea level.
High urea levels in the body can be caused by factors such as kidney dysfunction, dehydration, high protein diet, certain medications, and conditions like heart failure or gastrointestinal bleeding. When the kidneys are unable to efficiently filter urea from the blood, levels can rise, leading to conditions like uremia.
BUN acronym stands for Blood-Urea-Nitrogen It is a lab often obtained to aid in determining kidney functioning and usually is compared or obtained along with blood Creatinine levels. If levels are high it is often an indication of impaired kidney functioning. Normal level should be: 10-20 mg/dl BUN acronym stands for Blood-Urea-Nitrogen It is a lab often obtained to aid in determining kidney functioning and usually is compared or obtained along with blood Creatinine levels.

An abnormally high blood urea level is most commonly due to kidney dysfunction, such as acute or chronic kidney disease. Other potential causes include dehydration, congestive heart failure, gastrointestinal bleeding, or certain medications. Further evaluation by a healthcare provider is needed to determine the underlying cause.
