Propeptide of Brain Natriuretic Peptide (NT-proBNP) Blood Test Item # LC143000 Sensitive indicator used to detect risk for cardiac dysfunction 0.0 0 Reviews|Write a review B-type natriuretic peptide (BNP) is a small protein secreted by the ventricles of the heart in response to excessive stretc...
其临床意义如下:(1)心衰的诊断和鉴别诊断:如BNP<100ng/L或NT-proBNP<400ng/L,心衰可能性很小,其阴性预测值为90%;如BNP>400ng/L或NT-proBNP>1500ng/L,心衰可能性很大,其阳性预测值为90%。急诊就医的明显气急患者,如BNP/ NT-proBNP水平正常或偏低,几乎可以除外急性心衰的可能性。(2)心衰的危险分层:有心衰...
NT-proBNP,结果升高无太大意义(即无特异性),阴性才有真正的临床意义。对个体病人来讲,心衰诊断评价的最佳指标为利钠肽(ANP)心房利钠肽和脑利钠肽在心功能不全早期、症状出现之前升高。研究集中在N末端心房利钠肽(NT-ANP)、脑利钠肽、及其前体N末端前脑利钠肽上。这些肽类因其一致的及极高的...
Before the test No preparation is needed for a BNP or NT-proBNP test. During the test The BNP or NT-proBNP test may be performed using a blood sample taken from a vein in your arm during a process called venipuncture. In this procedure, a health professional will cleanse the puncture ar...
Another biomarker of left ventricular dysfunction that could be added to the armamentarium of the generalist is the blood test proBNP, the precursor of brain natriuretic peptide (BNP). Studies have shown that, already in early phases of left-ventricular systolic dysfunction (asymptomatic left ...
Test Details Methodology Electrochemiluminescence (ECLIA) Reference Range(s) 0-74 years<125 pg/mL ≥75 years<450 pg/mL Alternative Name(s) BNP LOINC® Codes, Performing Laboratory Service Area must be determined Preferred Specimen(s) 1 mL plasma collected in an EDTA (lavender-top) tube ...
Methods: According to the CURB-65 score, One hundred and thirty-three patients with clinical diagnosis of CAP were included, and NT-pro-BNP, D-dimer, PCT and lactate acid were detected after collecting blood samples from the above patients. Chi-square test was used to analyze the difference...
(38–149) Blood test at initiation of hospitalization Serum NT-pro BNP level 11530.9 ± 12062.0 (507.1–83097.0) WBC 10.1 ± 4.9 (2.9–39.9) Hb 11.5 ± 2.5 (5.3–20.1) Na 137.7 ± 5.9 (118–157) K 4.1 ± ...
The evaluation of this test shows an excellent repeatability, the absence of hook effect for very high values of NT-proBNP, the absence of BNP recognition and a robustness compared to the interferences classically checked: haemolysis and turbidity. The correlation of this total blood assay with a...
BNP,在常规超声心动图的基础上计算出左心室重量指数(LVMI).分析1,HFNEF患者的发病特点.2,血浆NT-pro BNP,左心室重量指数分别作为诊断HFNEF标准的敏感性,特异性,阳性预测值,阴性预测值.3,以血浆NT-pro BNP做为反映左室充盈压的间接指标,比较左心室重量指数与血浆NT-pro BNP的相关性.4,血浆NT-pro BNP与NYHA...
