摘要 目的为验证核酸检测的标本采集后至离心前保存时间4、12、24 h对核酸试验检测结果的影响,为核酸检测的过程控制、检测策略等提供数据支持。方法配制试验用HBV、HIV-1、HCV的三项弱阳性标本,共90支,每项30支,每支5 mL。将90支试验用弱阳性标本分为3组,每组每项为10支,分别置于4℃环境下保存4、12、24 h后,在1600 g,4℃条件下离心15 min。采用Procleix Tigris系统对这90支试验用弱阳性标本进行三项联合检测。结果核酸检测的标本采集后至离心前保存时间4、12、24 h对核酸试验检测结果无统计学意义(P>0.05),3个组样本检出结果均为反应性。结论核酸样本采集后可以保存于4℃,0~24 h之内离心处理,进行常规检测,不会对检测结果造成影响。
