BUN Test: Meaning Explained

If you're thinking, "What a BUN test is" it is a test performed to assess the function of your kidneys. It is conducted by measuring the quantity of urea nitrogen in the blood. Generally, urea nitrogen is a waste product produced in the liver when proteins are broken down. The kidneys filter this waste and eliminate it through the urine.
When the liver or kidneys are weak, BUN levels rise. Too much urea nitrogen in the blood might indicate liver or kidney issues.

Who Requires a BUN Test?

Your doctor may order a BUN test as part of a standard check-up or if you have or are at risk of having a kidney disease. Early kidney diseases often have no signs or symptoms. If you have any of the conditions outlined below, you are more prone to develop kidney disease:

  • Diabetes
  • Family of kidney problems
  • Heart disease
  • High blood pressure

If you have signs of later-stage renal disease, your physician may evaluate your BUN levels based on the following:

  • If you frequently itch your skin
  • If you need to urinate less or more often than usual
  • If you have trouble sleeping
  • If you experience muscle cramps
  • If there's swelling in your ankles, legs, or feet

Why Is a BUN Test Carried Out?

A Blood Urea Nitrogen test is often used to assess kidney function. It is frequently performed with other blood tests, like a creatinine blood test, to conduct a suitable treatment.

A BUN test report can aid in the diagnosis of the following conditions:

  • Malnutrition
  • Liver damage
  • Dehydration
  • Poor circulation
  • Gastrointestinal bleeding
  • Congestive heart failure
  • Urinary tract obstruction
  • High Protein levels
  • A recent heart attack

The test could be used to assess the efficacy of dialysis treatment. BUN tests are also commonly used in routine examinations, hospital stays, or after or during treatment for illnesses like diabetes. A BUN test detects the quantity of urea nitrogen in the blood but does not reveal the reason for an elevated or decreased urea nitrogen count.

How Is a BUN Test Conducted?

A BUN test is a basic blood test that requires the collection of a tiny sample of blood.

A technician will wipe a region of your upper arm with an antiseptic before extracting blood. They'll wrap an elastic band around your arm, causing your veins to expand with blood. A sterile needle will then be inserted into a vein, drawing blood into a tube linked to the needle. When the needle is inserted, you may experience mild to severe discomfort.

Once enough blood has been collected, the technician will withdraw the needle and apply a bandage to the puncture site. Your blood sample will be sent to a laboratory for examination. Your doctor will contact you again after going through the test results.

What Does the BUN Test Report Indicate?

BUN levels are measured in mg/dL (milligrams per deciliter). Normal levels vary according to age and gender. It is also worth noting that each laboratory has distinct normal ranges.

Normal BUN levels are often seen in the following ranges:

  • Children (aged 1 to 17) - 7 to 20 mg/dL
  • Adult Women - 6 to 21 mg/dL
  • Adult Men - 8 to 24 mg/dL

Note: BUN levels in adults over 60 are more significant than in those under 60 years. Also, remember that certain medicines, like antibiotics, might cause an increase in Blood Urea Nitrogen levels.
Lower BUN levels may indicate:

  • Overhydration
  • Lack of protein in the diet
  • Malnutrition
  • Liver failure

Based on the findings of your tests, your doctor may order more tests to confirm a diagnosis or to propose treatments. The most effective strategy to reduce BUN levels is through proper hydration. A low-protein diet can also aid in the reduction of BUN levels. BUN levels should not be relieved with medication.

However, elevated BUN levels may not always indicate a renal problem. Dehydration, pregnancy, high or low protein consumption, steroids, and age can all affect your BUN levels without showing a health risk.

What Are The Potential Risks of a Blood Urea Nitrogen Test?

Unless you have an emergency medical issue, you should be able to resume your routine activities after a BUN test. If you have a bleeding issue or are taking specific drugs, such as blood thinners, inform your doctor. It might cause you to bleed more than usual throughout the test.

A BUN test can cause the following side effects:

  • Bruising at the puncture area
  • Bleeding at the puncture area
  • Infection at the puncture area
  • Blood buildup under the skin

Patients may be dizzy or faint after the blood test in rare circumstances. Notify your doctor if you have any unexpected or long-lasting effects following the test.

What Foods Must be Avoided If BUN Levels Are High?

You should avoid or restrict high-protein diets if your Blood Urea Nitrogen levels are elevated. High-protein foods include the following:

  • Dairy Products: Yogurt, Cheese, and Milk
  • Meats: Salmon, Pork, Chicken, and Beef

What Foods Must be Consumed to Reduce High BUN Levels?

A low-protein diet can also aid in the reduction of elevated BUN levels. Low-protein foods that are healthy include:

  • Fruits: Bananas, Berries, and Apples
  • Healthy Fats: Coconut Oil, Nuts, and Avocados
  • Vegetables: Broccoli, Peppers, and Leafy Greens
  • Grains: Pasta, Rice, and Oats
