A Blood Urea Nitrogen Test (BUN) is a simple and inexpensive way to measure the amount of urea in the blood. This test diagnoses conditions such as renal failure, dehydration, and liver disease.
The BUN Blood Test checks for urea nitrogen in the blood. Urea nitrogen can be a sign of kidney problems or other health problems. BUN levels can be affected by several things, including dehydration, liver problems, and kidney problems. A high BUN level may indicate a problem with the liver or kidneys.
BUN is produced when the body breaks down amino acids. The level of BUN in the blood can indicate several health problems, including kidney failure and liver disease.
In this blog post, we will provide an overview of the BUN test, explain what preparation is necessary, and discuss the price and results of the test.
What is The Blood Urea Nitrogen Test?
The Blood Urea Nitrogen Test (BUN) is a laboratory test used to diagnose and monitor kidney function. The test is typically performed on a sample of blood taken from the arm or leg. The BUN level reflects the amount of nitrogen in the blood and is measured as an average over two to four hours after a meal.
The Blood Urea Normal Range is 6 to 24 mg/dL (2.1 to 8.5 mmol/L).
Elevated levels may suggest kidney impairment, while low levels may indicate renal disease or malnutrition. If the Blood Urea Normal Range is above 30 mg/dL (11.1 mmol/L) may indicate renal failure.
The cost of the BUN Blood Test varies according to the location and type of testing involved per lab draw. It typically takes two weeks for the results to come out.
What to Expect
When you visit the doctor, they may order a Blood Urea Nitrogen Test (BUN). A BUN test is used to diagnose kidney problems and can also suggest other medical issues.
Expectations during a BUN Blood Test:
- If your Blood Urea Normal Range is more than 40 mg/dL, your doctor may offer treatment options like medication or surgery.
- You will get a phone call from your doctor or healthcare professional requesting a BUN test.
- You will be urged to consume a large amount of water before your visit and to abstain from consuming alcohol 48 hours before the exam.
- Before and after the BUN test, you will need to provide a urine sample.
- When the technician draws blood from your arm, you may feel pressure.
- During and after your BUN test, you may have moderate to severe cramps. This often lasts around 30 minutes and disappears by itself.
- The findings will be available within 24 to 48 hours after your session.
- You may have slight cramping during or after your session; however, these cramps normally subside within a few minutes.
- If you have high blood pressure, are pregnant, or are nursing, you should address any concerns you may have about doing a BUN test with your doctor or healthcare provider before undergoing the test.
Preparation for BUN Test
Many people are unaware of the importance of having a BUN test performed regularly. A BUN level above 18 mg/dL is generally considered an indicator of kidney dysfunction and may signal the need for further testing or treatment.
The following steps outline the process for preparing for a BUN Blood Test:
1. Check with your doctor to see if you are at risk for developing renal dysfunction. This can include a history of diabetes, hypertension, or chronic liver disease.
2. If you are at risk, discuss with your doctor how frequently a BUN test should be performed and what the range should be.
3. Be aware that several factors can affect your BUN level, including age, sex, and weight. Therefore, it is important to keep track of your levels at regular time intervals so that you can identify any changes.
4. If you have been diagnosed with renal dysfunction, follow your doctor’s instructions regarding preparing for a BUN test. Common preparations include restricting fluid intake before the test (drinking plenty of water before the appointment), taking medications prescribed by your doctor, and avoiding alcohol consumption for 24 hours before the test.
5. Schedule your blood draw appointment as soon as possible after completing these preparations so that your blood will still be fresh when tested.
Cost of BUN Test
Generally, the cost of a BUN Blood Test varies depending on your location. The cost of a BUN test can range from Rs 100 to Rs 500. The test determines the blood’s BUN level and can diagnose problems such as renal failure or cirrhosis.
Results of BUN Test
The Blood Urea Nitrogen Test (BUN) measures the amount of protein in a person’s blood. The level of BUN indicates the extent of liver damage and can help determine an illness’s severity.
Around 6 to 24 mg/dL (2.1 to 8.5 mmol/L) is generally considered Blood Urea Normal Range. A level above 30 mg/dL (11.1 mmol/L) may be a sign of kidney disease, while a level below 20 mg/dL (7.9 mmol/L) may indicate liver or renal impairment.
A high BUN level indicates that your kidneys aren’t performing properly. However, increased BUN may be caused by a variety of different illnesses and disorders, including:
- Kidney disease
- Urinary tract infections
- Obstruction of the urinary tract (e.g., prostate cancer, fibrous compression of the ureter)
- Acute kidney injury (AKI)
- Diabetes mellitus
- Chronic renal failure
- Pregnant women
- Diseases that affect the liver, such as cirrhosis or hepatitis C, can lead to a high BUN level.
When is a Blood Urea Nitrogen (BUN) Test Recommended?
If you experience any of the following symptoms, it is generally recommended that you have a Blood Urea Nitrogen Test (BUN):
– Increased thirst
– Nausea or vomiting
– Fatigue
– Muscle cramps
– Kidney stones
If you are experiencing any of these symptoms and your doctor does not believe they are related to a medical condition, they may order a BUN Blood Test. If your BUN level exceeds 18mg/dl, you may be at an increased risk of developing kidney problems.
