Everything You Need to Know About B-Type Natriuretic Peptide (BNP) Tests

A B-type natriuretic peptide (BNP) test is a blood test used to measure the amount of BNP in the blood. BNP is a hormone produced by the heart that helps regulate blood pressure and fluid balance in the body. The BNP test is used to diagnose heart failure and other heart conditions.

When is a B-type natriuretic peptide (BNP) test performed?

A BNP test is usually ordered when a person has symptoms of heart failure, such as shortness of breath, fatigue, and swelling in the legs and feet. It may also be ordered if a person has a history of heart disease or is at risk for developing heart disease.

What is BNP?

BNP stands for B-type natriuretic peptide. It is a hormone produced by the heart that helps regulate blood pressure and fluid balance in the body. BNP is released when the heart is under stress, such as when it is working harder than normal.

How does a BNP test or NT-proBNP test work?

A BNP test measures the amount of BNP in the blood. The NT-proBNP test measures the amount of a related hormone, NT-proBNP, in the blood. Both tests are used to diagnose heart failure and other heart conditions.

What should I expect during a BNP test or NT-proBNP test?

During a BNP or NT-proBNP test, a healthcare provider will draw a sample of your blood. The sample will be sent to a laboratory for analysis.

What should I expect after a BNP or NT-proBNP test?

After a BNP or NT-proBNP test, you should not experience any side effects.

What are the benefits of a BNP or NT-proBNP test?

The BNP and NT-proBNP tests are useful for diagnosing heart failure and other heart conditions. They can also help monitor the effectiveness of treatment for heart failure.

What are the risks of a BNP test?

The risks of a BNP test are minimal. The most common risk is pain or discomfort from the needle used to draw the blood sample.

When should I know the results of a BNP test?

The results of a BNP test are usually available within a few days. Your healthcare provider will discuss the results with you.

What do abnormal levels of BNP mean?

Abnormal levels of BNP can indicate heart failure or other heart conditions. Your healthcare provider will discuss the results with you and recommend further testing or treatment if necessary.

When should I call my doctor about a BNP or NT-proBNP test?

You should call your doctor if you have any questions or concerns about a BNP or NT-proBNP test.
