what is the normal b natriuretic peptide
The B-type Natriuretic Peptide (BNP) Test is a blood test for heart failure. It measures the level of B-type natriuretic peptide in your blood. Your heart 's ventricles produce extra B-type natriuretic peptide when they can't pump enough blood to meet your body's needs.So if your B-type natriuretic peptide level is high, you probably have heart failure.The higher the levels are at diagnosis, the worse your heart failure is likely to be. The finding of low levels tends to exclude heart failure.o if your B-type natriuretic peptide level is high, you probably have heart failure.
