The normal range for brain natriuretic peptide levels is zero to 99 picograms per milliliter, notes WebMD. This can also be converted to zero to 99 nanograms per liter. Brain natriuretic peptide is made in the heart and appears in the blood, states WebMD. When the heart works harder, it releases more brain natriuretic peptide.

Brain natriuretic peptide (BNP) test is a blood test that measures levels of a protein called BPN that is made by your heart and blood vessels. BNP levels are higher than normal when you have heart failure.

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.

Serum creatinine, however, was not associated with higher BNP concentrations. 14 Accordingly, the 95th and 97.5th centiles of normal BNP values in adults aged 20–49 years were slightly higher than the corresponding values in our study. Our data are in line with the very few published reports dealing with BNP values in healthy children.

We have shown age and sex specific trends in normal values of plasma B type natriuretic peptide from infancy to adolescence using a commercially available rapid assay. Plasma BNP concentrations in newborn infants are relatively high, vary greatly, and decrease rapidly during the first week of life.

NT-proB-type Natriuretic Peptide (BNP) blood test. B-type natriuretic peptide (BNP) is a hormone produced by your heart. N-terminal (NT)-pro hormone BNP (NT-proBNP) is a non-active prohormone that is released from the same molecule that produces BNP. Both BNP and NT-proBNP are released in response to changes in pressure inside the heart.

A Comprehensive Guide to Normal Lab Values. Laboratory tests are procedures wherein a sample of blood, urine, other bodily fluid or tissue are checked in order to know more about a person’s health. The results of the test will show if a person is within the normal lab values. What are normal lab values?

Abstract. Aims To define the N-terminal pro-brain natriuretic peptide (NTpBNP) normal range, assessing its cardiovascular screening characteristics in general population and higher risk subjects.. Methods and results A total of 2320 subjects (1392 general population and 928 high-risk) ≥45 years old, selected randomly from seven community practices, were invited to undergo clinical assessment ...

a serum BNP level less than 100 pg/ml (29 pmol/litre) or an NTproBNP level less than 400 pg/ml (47 pmol/litre) in an untreated patient makes a diagnosis of heart failure unlikely the level of serum natriuretic peptide does not differentiate between heart failure due to left ventricular systolic dysfunction and heart failure with preserved left ...

When you have heart failure, your heart makes two proteins. 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 ...
