NT-proBNP

Your doctor will call them B-type natriuretic peptide (BNP) and N-terminal-pro-BNP (NT-pro-BNP). Levels of both in your blood go up when your heart failure gets worse and go down when it gets better. A test called a BNP blood test measures those two important levels. It’s able to spot heart failure more than 80% of the time.
