NT-proBNP (N-terminal pro-B-type Natriuretic Peptide) is released by the heart when it is under stress or working harder than normal. Elevated levels strongly suggest heart failure and correlate with its severity. This test is especially useful for evaluating unexplained shortness of breath — distinguishing cardiac causes from pulmonary ones — and for monitoring the effectiveness of heart failure treatment over time.
N-terminal pro-Brain Natriuretic Peptide — a hormone released by stressed cardiac ventricles. The single best blood marker for diagnosing and monitoring heart failure.
Anyone with unexplained shortness of breath, leg swelling, exercise intolerance, or known heart-failure risk factors (HTN, CAD, prior MI, diabetes, age 65+ with cardiac symptoms).

Both are released by stressed cardiac muscle. NT-proBNP has a longer half-life (60-120 min vs 20 min for BNP) so values are higher and more stable for routine testing. Cutoffs differ; clinicians use whichever their lab runs.
TestWell charges $224.99 — vs $99 at Quest Direct and $150-$350 at hospital labs.
Age-adjusted cutoffs (heart failure unlikely if below): <50y: <450 pg/mL; 50-75y: <900; >75y: <1800. Above these thresholds, heart failure becomes increasingly likely and warrants echocardiogram and cardiology evaluation.
Age, atrial fibrillation, kidney disease, pulmonary embolism, sepsis, and severe anemia all elevate it. Obesity falsely lowers it. Always interpret with symptoms and other cardiac testing.
NT-proBNP (Heart Failure Marker) test results are typically ready in 1–3 business days after your draw at Quest or Labcorp. TestWell emails you the moment they post, and your results dashboard shows each marker against its reference range with a plain-English explanation.
