Urea nitrogen is considered a waste of products. This develops when the body breaks down the protein from the food we eat. It builds up in the liver and moves through the blood to your kidneys, which then filter out of the blood. It leaves the body through urination or pee. The BUN test helps to indicate whether the urea nitrogen levels have risen beyond the normal range, indicating a potential problem with kidney functionality.
The BUN is required to assess kidney function and can be used to diagnose a variety of conditions, such as kidney disease, urinary tract infection, and dehydration. It is also commonly used to monitor people with chronic kidney disease or those undergoing dialysis treatments. A BUN test is a simple procedure that requires only a small sample of blood.
The BUN test is usually advised when a patient is showing signs of kidney disease, such as fatigue, itching, muscle cramp, swelling in the feet and ankles, and dark-colored urine. It can also be recommended for people who are at risk for developing kidney problems due to certain medical conditions or medications. In addition, it can be used to monitor patients who are already receiving treatment for renal diseases.
Early kidney disease tends to have no signs or symptoms. Persons may be more at risk of developing kidney disease if he or she has:
- Family history of kidney disorders
- Diabetes
- High blood pressure
- Heart disease
What is a Normal Range of Blood Urea Nitrogen Level?
A normal blood urea nitrogen level varies according to age and sex.
Age and Sex Normal BUN Level (mg/dL) Children between 1 and 17 years. Between 7 and 20 mg/dL. Adult women and people assigned female at birth. Between 6 and 21 mg/dL. Adult men and people assigned male at birth. Between 8 and 24 mg/dL.
High blood urea nitrogen indicates-
- High-protein diet
- Dehydration.
- Burns.
- Blockage in the urinary system
- Stress.
- Heart attack.
- Gastrointestinal bleeding
Low blood urea nitrogen indicates-
- Small body type.
- Overhydration
- Liver disease.
A BUN test is just one kind of measure of renal function. If the doctor thinks that a person is having kidney disease, he may ask for additional tests. These may include tests to measure:
- Creatinine
- GFR
