Natriuretic peptides are substances made by the heart. Two main types of these substances are brain natriuretic peptide (BNP) and N-terminal pro b-type natriuretic peptide (NT-proBNP). Normally, only small levels of BNP and NT-proBNP are found in the bloodstream. High levels can mean your heart isn't pumping as much blood as your body needs. When this happens, it's known as heart failure, sometimes called congestive heart failure. Natriuretic peptide tests measure the levels of BNP or NT-proBNP in your blood. 1
Other names: brain natriuretic peptide, NT-proB-type natriuretic peptide test, B-type natriuretic peptide. 1

NT-Pro BNP levels are loosely correlated with New York Heart Association (NYHA) functional class, ranging from 31 pg/mL to 26,916 pg/mL, with median values ranging from 377 pg/mL to 3,130 pg/mL 2. Depending on the lab, have 0 pg/mL is a plausible value 3. This information combined with a data-driven approach to empirically establish possible low and high values, leads us to choose 0 and 27,000. As one nanogram = 1000 picgrams, it follows that the plausible low and high values for ng/mL are, 0 and 27 respectively.
