POCT法和常规检测法在BNP检测中的对比分析

Comparative analysis of POCT and routine test in BNP testing

目的比较即时检验(POCT)法和常规检测法在B型钠脲肽(BNP)检测中的相关性。方法运用Alere Triage?MeterPro(美国)荧光免疫分析仪或Beckman Coulter Access?2化学发光仪分别检测40份住院患者全血或血浆样本中BNP含量,按照CLCS EP9-A2文件要求进行对比分析。结果 POCT法和常规检测法检测住院患者血样BNP含量的线性回归良好,相关系数(r)=0.999 7。结论 POCT法和常规检测法在BNP检测中的相关性良好,POCT法具有较高的可靠性,可以用于临床检测。

Objective To analyze the relevance between the point-of-care testing （POCT） and routine test in BNP testing .Meth-ods The whole blood samples or plasma samples from 40 inpatients were detected brain natriuretic peptide （BNP） by the Alere Triage？ MeterPro fluorescence immunoassay analyzer （POCT ） or the Beckman Coulter Access ？2 chemiluminescence analyzer （routine test） ,respectively .The acquired data were subjected to comparative analysis according to the CLCS EP 9-A2 .Results The linear regression of the BNP content in the blood samples detected by POCT and the routine test was good ,the correlation coeffi-cient（r） was 0 .999 7 .Conclusion POCT and the routine test have good correlation in BNP testing .POCT for BNP testing has higher reliability and is applicable for clinical detection .
