Blood Urea Nitrogen (1) Test

Blood Urea Nitrogen (1) Test

also known as: BUN test, Serum Urea Nitrogen Blood, Serum Urea Nitrogen, Urea Nitrogen

Kidneys are the important part of the body that help filtering out excess water, controlling the fluid balance, and keeping the electrolyte level. As people get older and since the kidneys do a lot of cleansing activities, it is essential to make sure if the kidneys are functioning properly. The blood urea nitrogen test helps the doctor to analyze the following:

  • Malnutrition
  • Poor blood circulation in the kidneys
  • Urinary tract obstruction
  • Heart failure
  • Gastrointestinal bleeding
  • This test may also help the doctor analyze the requirement for dialysis treatment.

If your doctor recommends you to test the urea nitrogen level in the blood, then there is no requirement to ensure the sample quality. You can follow your regular diet before providing the sample. If your doctor recommends for additional tests, then you may have to fast for some time before providing the sample.

The results for the blood urea nitrogen test is measured in mg/dL, which is referred to as milligrams per deciliter. The test results may depend on the age and gender of the person. It is also necessary to note the laboratories might provide different ranges to specify it as normal. It is always recommended to consult with a doctor to know about the normal range. The following are the desirable ranges for urea nitrogen test: 8 to 20 mg/dL for adult men

  • 6 to 20 mg/dL for adult women
  • 5 to 18 mh/dL for kids
  • If the results have high ranges for urea nitrogen, then it can indicate the following: Kidney failure
  • Kidney disease
  • Dehydration
  • Heart attack or heart failure
  • High levels of protein
  • After you visit the lab, the lab technician cleans your skin with a cotton or an alcohol pad. Make sure that the lab technician uses a brand new syringe and needle for collecting the blood sample. The blood is then taken by injecting the needle on the skin that is cleaned. After taking the blood, the sample is then stored in to a container and then the container is marked with your name. The blood sample is then used for testing. The blood reports are handed over to you and you can proceed for further analysis with your doctor.

    Both decreased and increased BUN concentrations may be seen during a normal pregnancy.
