BNP Blood Test (B-Type Natriuretic Peptide)
Know your heart's strain before symptoms take hold.
The BNP blood test measures B-type Natriuretic Peptide, a hormone released by the heart's ventricles when they are stretched or working under increased pressure. It is a simple blood test used to help detect, assess, and monitor heart failure and other cardiac conditions. It is particularly useful for patients presenting with breathlessness, fatigue, or swelling, where the cause may be cardiac or non-cardiac, and for monitoring those with known heart failure.
What is measured
- B-type Natriuretic Peptide (BNP): A cardiac hormone that rises when the heart is under strain, helping to differentiate heart failure from other causes of similar symptoms and to gauge the severity of cardiac stress.
Why it matters
BNP provides a direct, objective window into how hard your heart is working. Early detection of elevated BNP can prompt timely investigation and treatment, improving outcomes and quality of life. Whether you are experiencing unexplained breathlessness or managing an existing cardiac condition, this test offers clear, actionable insight into your heart's health.
