Introduction to B Type Natriuretic Peptide (BNP) Test

Our heart and blood vessels produce proteins. B-type natriuretic peptide (BNP) is one such protein. The BNP test checks the level of BNP protein in the blood. It also detects the functioning of the heart. The BNP test detects and diagnoses current symptoms of heart condition. 

Maintaining a healthy heart is necessary for overall health. It provides strength to your immune system. A doctor may recommend taking the BNP test to evaluate the heart’s functioning. Early detection may help in preventing any serious health complications.

If you see signs of heart disease or your doctor recommends taking the BNP test, prefer Redcliffe Labs. Redcliffe Labs has years of experience in diagnostic services. Our team is an expert in conducting tests. We offer a home sample collection service with 3600+ tests.

Test Details in Brief 

What are Natriuretic Peptide Tests?

Your blood vessels and heart produce natriuretic peptides. These proteins in the blood prevent heart disease or failure. Natriuretic peptide tests help confirm the symptoms and causes of heart failure. There are two natriuretic peptides: brain natriuretic peptide and N-terminal pro-b-type natriuretic peptide. 

A doctor should take the test in case they detect any symptoms of heart failure or disease. Your body might give signs like trouble pumping oxygen to the blood. After looking at the condition, your healthcare provider might recommend a BNP test or NT-Pro BNP test. 

A brain natriuretic peptide (BNP) test monitors the blood BNP levels. It is a protein released by the heart in response to high pressure due to heart failure. 

The N-terminal pro-B-type natriuretic peptide test monitors the level of BNP, a precursor to BNP. NT-proBNP is present in BNP. 

Your blood has a normal level of BNP and NT-proBNP. However, elevated levels may lead to the risk of heart failure. Factors such as age, weight, gender, family history, and medical history affect the BNP's normal range. 

What is a BNP?

Your body needs protein for regular circulation of blood. Brain Natriuretic Peptide is one of those proteins. It is present and released through the heart. However, some people refer to it as ‘brain’ because it was first discovered in the brain tissues. 

The left ventricle pumps huge amounts of blood through the heart, which flows straight to the body. It is the primary organ producing BNP. Excessive load or stress puts immense pressure on the left ventricle, which raises BNP levels. Further, it prompts the kidneys to release salt and water, creating a natriuretic situation. 

What is the BNP Test?

B-type Natriuretic Peptide test or BNP test is a blood test. It detects the level of BNP in the blood and monitors heart health overall. Some healthcare professionals may call this test with Aminoterminal pro-B-type natriuretic peptide, B-type natriuretic peptide, NT-pro b-type natriuretic peptide, and N-terminal pro-B-type natriuretic peptide. 

A doctor might recommend the test to check the symptoms of heart failure, the situation, and the functioning of the heart. The test also detects whether the condition worsens, improves, or remains the same. If you take any heart failure medications, the BNP lab test may detect their functioning. 

What is the Purpose of the BNP Test?

The BNP Test checks the protein levels in the blood. However, there are other purposes too. These include: 

• To diagnose any heart failure
• To examine the severity of heart condition. 
• To monitor the response of the treatment to therapy. 
• To look at the symptoms or signs affecting heart failure. 
• To help doctors diagnose patient’s medical conditions. 
• To check the BNP levels in the blood. 
• To check for cardiovascular diseases.

Signs and Symptoms indicating why you need the BNP test

Your body gives indicates several signs of heart failure. Here are certain symptoms and signs of heart failure: 

• Fatigue 
• Shortness of breath
• Cough 
• Extreme weakness
• Swelling in the abdomen, legs, feet, or veins
• Unable to sleep 
• Loss of appetite
• Nausea 
• Frequent peeing 
• Unexplained weight gain 
• Abnormal heart rate 
• Obesity 
• Lung or kidney disorder (in extreme cases) 
• Heart palpitation 
• Confusion 
• Trouble in remembering things
• Dry cough 
• Dizziness 
• Wheezing 

What is The BNP Test Used For?

The primary use of the BNP test is to detect and diagnose heart failure. Breathing problems are common signs. Insufficient supply of oxygen creates a situation of shortness of breath. Nonetheless, the BNP lab test may also be used: 

• To find the seriousness of the heart condition 
• To know the situation of heart failure
• To detect the chances of the condition getting worse
• To check the symptoms 
• To see the cause of heart failure

Other reasons a doctor may recommend the BNP test include: 

• Had a heart attack 
• On heart-related medications
• Unstable angina 
• Sudden worsening of heart function.

Redcliffe Labs offers the BNP test price at INR 1900. They offer a home sample collection service, making it efficient and comfortable for you.

What Does The BNP Test Measure?

The BNP test measures BNP or NT-proBNP levels in the blood. It detects the BNP normal range. The body releases BNP, a protein, into the blood in response to uncertain pressure or stress. Abnormal BNP levels may lead to kidney or liver failure. 

If your doctor suspects signs such as difficulty breathing, swelling in your legs, and fatigue, they might suggest the BNP or Nt-proBNP tests. If you detect these signs, consult a doctor. 

Why does A Doctor call for a B-type natriuretic Peptide Test?

A doctor may call for the BNP test if they see signs of: 

• Fatigue 
• Nausea 
• Vomiting 
• Dizziness
• Fainting 
• Weakness
• Shortness of breath 
• Wheezing
• Unnecessary tiredness
• Heart palpitations
• Loss of appetite 
• Swelling in the legs, abdomen, or feet 
• Frequent urination 
• Unexplained weight gain 
• Abdomen pain

Preparation for the BNP Test 

The BNP test is a blood test that requires no major preparations. However, a healthy diet may help regulate correct blood flow. Certain guidelines might prevent report hindrances. 

1. Dehydration may lead to weakness. To prevent certain side effects, keep your body's hydration level stable by drinking at least 8-10 glasses of water a day. 
2. Abnormal BNP may raise several questions, leading to stress; try to keep your mind calm. 
3. Clear all your doubts with your healthcare provider. 
4. Don’t suddenly get up from the bed for the blood test to give blood samples. 

The procedure of the BNP Test 

The BNP test requires blood samples. Our phlebotomists will reach your home to collect samples. They will insert a sterile syringe into your vein for blood sample collection. They will clear the site with an antiseptic wipe and later insert a syringe. It may create a puncture. Later, they will transfer the sample into a container for testing. They might hold the punctured site with a cotton swab to prevent excessive bleeding. 

Once you have completed the process, you will receive the test reports within 36 hours. Redcliffe Labs offers a competitive and affordable BNP test price of INR 1900. 

Risks Associated with the BNP Test 

BNP lab test requires a blood sample, which might cause slight pain, excessive bleeding, weakness, fatigue, nausea, hematoma, soreness, and lightheadedness. 

The Result Interpretation of the BNP Test

The unit is measured in picograms per milliliter (pg/mL) or picomoles per liter (pmoI/L). However, test results depend on the lab and its equipment. Some labs may generate reports in nanograms per liter (ng/L). BNP test reports may vary depending on the patient’s age, gender, sex, medical history, family history, or excessive dosage of certain medicines. The test results may indicate normal, low, or high results. 

Normal levels of BNP are 100 pg/ml or less. Any range above or below indicates abnormality. If your test range falls under this, you have no sign of heart failure. However, your doctor may recommend conducting other tests like the NT-proBNP test. You can book the NT-proBNP test from Redcliffe Labs. 

The normal range may differ based on age. Here is a breakdown of BNP levels at different ages. 

Low Level

The high or elevated range represents signs of heart failure. Low BNP level has different causes. Low level arises mostly because of heart failure or obesity. A doctor might look at your situation and monitor if the level is low or high. The reasons for a low BNP level are: 

• Heart failure 
• Obesity 
• Certain heart condition 
• Lung condition 
• High blood pressure 
• Kidney failure 

High Level 

Elevated BNP level is a clear sign of heart disease. BNP tests detect the high or low levels of BNP in the blood. The reasons for a high BNP level are: 

• Heart failure 
• Abnormal heart structure 
• Abnormal hemodynamics 
• Low BNP levels 
• Severe infection 
• Pulmonary hypertension 
• Pulmonary embolism 
• Kidney failure 
• Lung problem
