Testing Details
B-Type Natriuretic Peptide (BNP) Test
The BNP test is a vital blood test used to assess heart function and detect heart failure. It measures B-type natriuretic peptide, a hormone released by the heart when it’s under stress. Elevated BNP levels often mean the heart is struggling to pump effectively, which may indicate acute or chronic heart failure.
Doctors order the BNP test to:
- Diagnose or rule out heart failure
- Differentiate heart issues from lung conditions
- Monitor treatment in patients with known heart disease
- Common symptoms that lead to BNP testing include:
- Shortness of breath
- Fatigue
- Leg swelling
- Fluid retention
The BNP test helps identify heart failure early, so treatment can begin sooner. It also supports accurate diagnoses and prevents unnecessary imaging or hospital visits.
This test is especially valuable for patients with high blood pressure, coronary artery disease, or irregular heart rhythms. It delivers critical insight into heart health and helps guide long-term care decisions.
