B-type Natriuretic Peptide – Normal Range

The normal values for B type natriuretic peptide are 100-300 pg/mL, and this range is unisex for all age groups.

Higher-than-normal results suggest that a person has some degree of heart failure, and the level of BNP or NT-proBNP in the blood is related to its severity.

Higher levels of BNP or NT-proBNP are often associated with a worse outlook (prognosis) for the person. Normal results indicate that the person’s symptoms are likely due to something other than heart failure.

The normal level of BNP is 0.5- 30 pg/mL (picograms/ millilitre).

Higher levels (greater than 400 pg/mL) indicate a high possibility of congestive heart failure that occurs due to the incompetent pumping of blood by the ventricles, consequently causing retention of blood in lungs and abdomen. The level of BNP increases rapidly on the occurrence of a heart failure.
