Key biomarker for heart failure risk — helps evaluate shortness of breath and cardiac function. 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. **Clinical use:** N-terminal pro-Brain Natriuretic Peptide — a hormone released by stressed cardiac ventricles. The single best blood marker for diagnosing and monitoring heart failure. ## Who should order it? 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). ## Biomarkers measured - [NT-proBNP](https://www.test-well.com/biomarkers/nt-probnp) ## Price by lab | Lab | Test price | All-in (with $6 fee) | Notes | | --- | --- | --- | --- | | Quest Diagnostics | $224.99 | $230.99 | Choose at checkout; walk-in patient service centers nationwide (not NY/NJ) | | Labcorp | $224.99 | $230.99 | Choose at checkout; walk-in patient service centers nationwide (not NY/NJ) | Rhode Island is not served.

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. ### How much does an NT-proBNP test cost without insurance? TestWell charges $224.99 — vs $99 at Quest Direct and $150-$350 at hospital labs. ### Do I need to fast? No fasting required. ### What's a normal NT-proBNP level? 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. ### What's the CPT code? 83880 (NT-proBNP). HSA/FSA eligible. ### What raises NT-proBNP besides heart failure? 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. ## How to order 1. Add to cart: https://www.test-well.com/cart?add=nt-probnp-heart-failure-marker&utm_source=ai_agent&utm_medium=markdown 2.
