The results of a Blood Urea Nitrogen test report are displayed in milligrams per decilitre (mg/dL). According to your age and gender, the normal values for blood urea nitrogen will vary. It should also be noted that different laboratories have different ranges for normal values. The table below outlines what the general normal blood urea nitrogen levels are defined as.
|Children between the ages of 1 to 17
||7 to 20 mg/dL
||8 to 24 mg/dL
||6 to 21 mg/dL
|Adults over 60 years
||8 to 23 mg
Your kidneys are functioning well if your blood urea nitrogen levels fall in the recommended range for your age and gender. However, if your blood urea nitrogen levels are higher or lower than the recommended range, it is a potential sign of kidney damage or disease. Therefore, it is best to consult with your doctor to ensure the results and whether treatment is required.
If you have done the Blood Urea Nitrogen test as part of a comprehensive metabolic panel, you will also receive the results for the other tests in the same report. This can better help you understand the significance of your blood urea nitrogen levels and their functioning.
