# B-Type Natriuretic Peptide (BNP)

> This test measures the level of B-Type Natriuretic Peptide (BNP), a hormone released by your heart when it is under pressure or working hard to pump blood. Doctors use this measurement to evaluate symptoms like shortness of breath and leg swelling to determine if heart stress is the cause. It helps distinguish between heart failure and other issues, such as lung conditions, that affect breathing. While elevated levels suggest heart strain, this test alone does not identify the specific underlying cause of the heart problem.
