The Blood Urea Nitrogen (BUN) test measures the amount of urea nitrogen present in the blood.
Urea is the principle waste product of protein catabolism. BUN is most commonly measured in the diagnosis and treatment of certain renal and metabolic diseases. Increased BUN concentration may result from increased production of urea due to (1) diet or excessive destruction of cellular proteins as occurs in massive infection and fevers, (2) reduced renal perfusion resulting from dehydration or heart failure, (3) nearly all types of kidney disease, and (4) mechanical obstruction to urine excretion such as is caused by stones, tumors, infection, or stricture. Decreased urea levels are less frequent and occur primarily in advanced liver disease and in overhydration.
The BUN test specifically checks for the concentration of urea nitrogen in the blood, which can be an indicator of kidney function. Elevated levels might suggest that the kidneys are not effectively eliminating urea from the blood, while low levels can have other implications.

The Blood Urea Nitrogen (BUN) Test works by collecting a blood sample and measuring levels of BUN. Abnormally high levels generally point to problems with your kidneys.
Your provider may order a blood test for candida antibodies to diagnose the overproduction of candida caused by either the disruption of healthy bacteria or a compromised immune system. Some factors may include pregnancy, antibiotic use, birth control pills, diabetes, immunosuppression, or HIV infection.
Your provider may wish to order a Blood Urea Nitrogen (BUN) Test if you’re exhibiting symptoms of kidney disease, such as:
You cannot take a Blood Urea Nitrogen (BUN) Test at home — this test can only be administered by a medical professional at a licensed testing facility.
Once you receive the results of your blood test for Blood Urea Nitrogen (BUN), you will need to consult with your provider. Only a medical professional can advise you on your BUN levels and help you develop a treatment plan if necessary.
Your BUN levels may fluctuate over time, depending on a variety of factors that could impact your liver or kidney function. A blood test for BUN can help monitor these changes over time.
