What is a probnp test?

The proBNP test measures the levels of pro-brain natriuretic peptide (proBNP) in the blood, which is a hormone produced by the heart in response to increased pressure and stress, often due to heart failure. Elevated proBNP levels can indicate heart dysfunction and help diagnose or assess the severity of heart failure. It is commonly used in clinical settings to guide treatment decisions and monitor patient progress.
