Vid utredning av misstänkt hjärtsvikt har NT-proBNP ett högt negativt prediktivt värde, det vill säga ett lågt värde (<125 ng/L eller vid akuta symptom <300 ng/L) kan tillsammans med ett normalt EKG med stor sannolikhet utesluta hjärtsvikt. Förhöjda värden kan förutom hjärtsvikt orsakas av många olika sjukdomstillstånd. 2

NT-proBNP =N-terminal prohormone of brain natriuretic peptide. B-type natriuretic peptide(BNP) levels were reduced by 25% in the Tekturna arm compared to 

ProBNP, comprising 108 amino acids, is secreted mainly by the ventricle and, in this process, is cleaved into physiologically active BNP (77‐108) and the N‐terminal fragment NT‐proBNP (1‐76). Studies indicate that NT‐proBNP can be used in diagnostic and prognostic applications.

Test Usage The N-terminal Pro-Brain Natriuretic Peptide (NT-Pro-BNP) is an assay used as an aid in the diagnosis of individuals suspected of having congestive heart failure. If your BNP or NT-proBNP results were normal, it probably means your symptoms are not being caused by heart failure. Your provider may order more tests to help make a diagnosis. If you have questions about your results, talk to your health care provider.

On the other hand, an NT-proBNP cut-off value of 318 pg/mL is more appropriate in differing patients with congenital nonspherocytic hemolytic disease (CNHD) from healthy patients, with 94% sensitivity and 97% specificity. Reference range: The BNSSG Suspected Heart Failure Care Pathway recommends the following cut-off values for NT-proBNP: Men under 70 yr: <100 pg/ml, Women under 70 yr: <150 pg/ml, All 70 yr and over : <300 pg/ml. Container: Serum (Gold top) Ideal volume (mL): 5 mL Referred outside NBT for analysis? No BNP tests, also called a B-type natriuretic peptide test, measure BNP by picograms (pg) per milliliter (mL) or nanograms per liter.

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. N-terminal proBNP and BNP peptide analysisThe N-terminal proBNP concentration in plasma was measured with a processing-independent assay (PIA); the validation of this assay has been reported previously [30].In brief, this assay quantifies the total concentration of both the intact precursor (proBNP 1-108) and the N-terminal fragment (proBNP 1-76) after a pre-analytical enzymatic step [31]. In fact, a BNP twice the normal range can indicate a quadruple risk of death in folks who don't even have symptoms.. There is no other test that has the ability to have this crystal ball power of determining your chances of succumbing to heart failure even if you have no symptoms. 2016-09-21 Conclusions A comparable renal elimination of N‐terminal proBNP and BNP is contrasted by a selective extraction of BNP in the lower extremity.

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.

Notably, the increase in the NT-proBNP levels was associated with the increased GEDVI (r = 0.61, p < 0.0001). Therefore, blood NT-proBNP may be a good indicator of cardiac preload in patients with high volume load Cleavage of the prohormone proBNP produces biologically active 32 amino acid BNP as well as biologically inert 76 amino acid N-terminal pro-BNP (NT-proBNP). Atrial natriuretic peptide (ANP) is a hormone that is released from myocardial cells in the atria and in some cases the ventricles in response to volume expansion and possibly increased wall stress [ 1 ].

AbstractThe aim of the present study was the investigation of N-terminal pro-brain natriuretic peptide (NT-proBNP) in the pediatric population. This is essential for adequate monitoring and classification of pediatric patients with heart disease, but no consistent data are available yet.
