當(dāng)前市面上雖已有很多廠家推出了相關(guān)檢測產(chǎn)品，但是在實(shí)際應(yīng)用的過程中也發(fā)現(xiàn)在一些不盡如人意的問題，央視白延松采訪呼吸與危重癥醫(yī)學(xué)**、中國工程院副院長、中國醫(yī)學(xué)科學(xué)院院長王辰的過程中，王辰院長指出當(dāng)前臨床確診患者用核酸檢測陽性的檢出率只有30-50%，大部分仍然是靠臨床癥狀的合理性推斷，這反映了當(dāng)前諸多分子快檢產(chǎn)品實(shí)際應(yīng)用中的不足。造成陽性率低的原因很復(fù)雜，從采樣、裂解、提取、擴(kuò)增、檢測各個(gè)環(huán)節(jié)的軟硬件及操作人為因素，都有可能影響到結(jié)果，致善生物研發(fā)生產(chǎn)的一次性使用采樣管可以瞬間滅活，保護(hù)檢測工作者；穩(wěn)定貯存RNA一個(gè)月以上，樣品轉(zhuǎn)運(yùn)無需冷鏈，這些特點(diǎn)可以使PCR檢測操作更便捷、檢測結(jié)果更準(zhǔn)確、具備更高的安穩(wěn)性，有利于回顧性地再研究樣本。 </p><p style="text-indent:25px">一次性使用病du采樣管（滅活型）特點(diǎn)：1.操作使用簡單，無需配液，體系內(nèi)含有高效病du裂解液，采樣后即刻滅活病du，有效防止二次傳播風(fēng)險(xiǎn)，保障運(yùn)輸及檢測人員安全；2.病duDNA/RNA可在常溫保存與運(yùn)輸1周不降解，按大多數(shù)商業(yè)化試劑盒進(jìn)行提取后，獲得的DNA/RNA質(zhì)量好，得率高，可完成各種基因檢測及分析實(shí)驗(yàn)，如PCR、qPCR等，同時(shí)節(jié)省運(yùn)輸成本；3.內(nèi)含核酸RNA酶克制劑，大化程度保護(hù)病du核酸穩(wěn)定不被降解，大幅提高核酸提取效率。4.適用于**病du、流感病du、手足口病du等常見病du樣本采集保存運(yùn)輸工作，可采集咽拭子鼻試子或特定部位組織樣本，儲存的樣本可用于后續(xù)的核酸提取或純化等臨床試驗(yàn)。采樣管的發(fā)布和使用可以更好幫助醫(yī)護(hù)人員采集和監(jiān)測采樣，使用方便。</p><div
