Test Overview. A brain natriuretic peptide (BNP) test measures the amount of the BNP hormone in your blood. BNP is made by your heart and shows how well your heart is working. Normally, only a low amount of BNP is found in your blood.
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.
