A BNP blood test measures a hormone your heart releases when it is under stress or not pumping effectively. It is most often ordered to help evaluate shortness of breath, swelling, or suspected heart failure.

What it measures

  • BNP — B-type natriuretic peptide, the hormone itself.
  • NT-proBNP — A related inactive fragment that is often measured instead and may stay in the blood longer.
  • Creatinine — A kidney waste product sometimes checked alongside BNP because kidney function affects BNP levels.
  • Electrolytes — Minerals such as sodium and potassium that can be checked with cardiac tests.

Who it is for

A doctor or emergency clinician typically orders a BNP test when someone has unexplained breathing difficulty, fatigue, or fluid buildup. It may also be used to monitor known heart failure.

Preparation

No fasting or special preparation is usually required. Tell your clinician about all medications and heart medicines, as some can affect the result.

Results and what they mean

Results are reported as a number in picograms per milliliter (pg/mL), with a reference range that varies by lab, age, and whether BNP or NT-proBNP was measured. A clinician interprets the number alongside your symptoms, exam, and other tests. This is general information, not medical advice; discuss your results with a qualified healthcare professional.

Frequently asked questions

Does a high BNP mean I have heart failure?

Not by itself. Many conditions can raise BNP, and a clinician uses the result with your history and other tests to decide what it means.

Can I eat or drink before the test?

Yes, fasting is not normally needed for a BNP test unless your clinician gives other instructions.

How long until I get results?

Typical turnaround is 1-3 business days, though urgent settings may have faster results.

Are BNP and NT-proBNP the same?

They are related but different markers, and their numbers are not directly interchangeable. Your lab report will say which one was measured.
