檢測(cè)特異序列的方法常見的是熒光定量PCR（聚合酶鏈?zhǔn)椒磻?yīng)）。因PCR反應(yīng)模板*為DNA，因此在進(jìn)行PCR反應(yīng)前，應(yīng)將核酸（RNA）逆轉(zhuǎn)錄為DNA。在PCR反應(yīng)體系中，包含一對(duì)特異性引物以及一個(gè)Taqman探針，該探針為一段特異性寡核苷酸序列，兩端分別標(biāo)記了報(bào)告熒光基團(tuán)和淬滅熒光基團(tuán)。探針完整時(shí)，報(bào)告基團(tuán)發(fā)射的熒光信號(hào)被淬滅基團(tuán)吸收；如反應(yīng)體系存在靶序列，PCR反應(yīng)時(shí)探針與模板結(jié)合，DNA聚合酶沿模板利用酶的外切酶活性將探針酶切降解，報(bào)告基團(tuán)與淬滅基團(tuán)分離，發(fā)出熒光。每擴(kuò)增一條DNA鏈，就有一個(gè)熒光分子產(chǎn)生。熒光定量PCR儀能夠監(jiān)測(cè)出熒光到達(dá)預(yù)先設(shè)定閾值的循環(huán)數(shù)（Ct值）與病毒核酸濃度有關(guān)，病毒核酸濃度越高，Ct值越小。不同生產(chǎn)企業(yè)的產(chǎn)品會(huì)依據(jù)自身產(chǎn)品的性能確定本產(chǎn)品的陽性判斷值。北京病毒保存液采樣拭子：植絨采樣頭對(duì)細(xì)胞、無毒性作用，且不含RNA酶，能比較大限度地增加樣本采集與吸附量。</p><div
