WHY BNP TEST IS DONE

What is the BNP Test?

The BNP test measures the level of B-type natriuretic peptide (BNP) in your blood. BNP is a hormone that is produced by your heart. The levels of BNP in your blood can increase when your heart is under stress. This can happen for a number of reasons, including:

• Heart failure
• Sudden cardiac arrest
• Acute coronary syndrome
• Cardiomyopathy
• Myocarditis
• Pericarditis
• Pulmonary embolism
• Sepsis
• Kidney failure
• Liver failure
• Thyroid disease

Why is the BNP Test Done?

The BNP test is used to:

• Diagnose heart failure.
• Determine the severity of heart failure.
• Monitor the effectiveness of treatment for heart failure.
• Diagnose other conditions that can cause shortness of breath, such as pneumonia or pulmonary embolism.
• Screen for heart failure in people who are at high risk for the condition, such as people with diabetes or high blood pressure.

BNP Test Results

The normal range for BNP levels in the blood is less than 100 pg/mL. BNP levels that are higher than 100 pg/mL may indicate that you have heart failure or another condition that is causing your heart to work harder than it should.

The higher your BNP level, the more severe your heart failure is likely to be. BNP levels that are higher than 500 pg/mL are associated with a high risk of death from heart failure.

BNP Test Limitations

It is important to note that some conditions other than heart failure can also cause BNP levels to increase; these include:

• Overdose on cocaine
• Kidney failure
• Liver failure
• Thyroid disease
• Obesity
• Pregnancy
• Strenuous exercise

If you have any of these conditions, your doctor may need to order other tests to confirm a diagnosis of heart failure.

How is the BNP Test Done?

The BNP test is a simple blood test. A blood sample is drawn from a vein in your arm and sent to a laboratory for analysis. The results of the test are usually available within a few hours.

Risks of the BNP Test

The BNP test is a safe procedure. There is a small risk of bleeding or bruising at the site of the blood draw.

Preparing for the BNP Test

There are no special preparations required for the BNP test. You can eat and drink as usual before the test.
