What is a BNP ( B - TYPE NATRIURETIC PEPTIDE)?

The B-Type Natriuretic Peptide (BNP) test is a blood test that measures levels of BNP, a hormone produced by the heart. BNP is released when the heart is under stress or strain, especially in conditions like heart failure. Doctors use this test to help diagnose or monitor heart failure, evaluate unexplained shortness of breath, and assess the severity of cardiac dysfunction. It provides valuable information about heart health and guides treatment decisions for patients with suspected heart disease.
