鼻咽拭子，仍是目前**為簡(jiǎn)便普及的方法2.確診患者中咽拭子的陽性率大致為30%-50%。前段時(shí)間王辰院士在**電視臺(tái)采訪時(shí)提出，確診患者中咽拭子的陽性率*為30%-50%；據(jù)四川大學(xué)華西醫(yī)院劉焱斌網(wǎng)絡(luò)始發(fā)的文獻(xiàn)報(bào)道，對(duì)武漢市紅十字會(huì)醫(yī)院100例***肺炎病例同時(shí)留取咽拭子和鼻拭子，深圳2019-nCoV鼻咽拭子，咽拭子陽性檢出率54%，而鼻拭子取樣標(biāo)本的***核酸陽性率89%；綜合分析如下：常見的客觀原因是：鼻，深圳2019-nCoV鼻咽拭子、咽拭子**常用，但與病程密切相關(guān)，早期***分布在上呼吸道，隨著病情發(fā)展，上呼吸道***被***，而下呼吸道***載量反而升高，到后期可能就不易從鼻、咽拭子檢出，深圳2019-nCoV鼻咽拭子。常見的主觀原因是：如果醫(yī)務(wù)人員采樣不熟練或位置不準(zhǔn)確；刮取標(biāo)本時(shí)患者的反應(yīng)比較大；采集時(shí)醫(yī)務(wù)人員正面對(duì)著被采樣者口腔，有飛沫和氣溶膠傳染途徑的風(fēng)險(xiǎn)，取樣時(shí)間較短或力度不夠，很難采集足夠標(biāo)本，導(dǎo)致檢測(cè)假陰性出現(xiàn)。3.棉拭子與尼龍植絨拭子的區(qū)別采樣拭子的材質(zhì)、質(zhì)量對(duì)樣本質(zhì)量也很重要。尼龍植絨拭子上的絨毛，能增加拭子與咽部接觸的表面積，可以**大化地轉(zhuǎn)移細(xì)胞到拭子的表面。一項(xiàng)國(guó)外的研究發(fā)現(xiàn)，植絨拭子在轉(zhuǎn)移表面微生物的效率比棉拭子高20%～60%。上海鼻咽拭子采購！深圳2019-nCoV鼻咽拭子</p><div

編審**：陳美芳北京大學(xué)人民醫(yī)院***科副主任醫(yī)師鼻拭子***核酸檢測(cè)和咽拭子***核酸檢測(cè)是***肺炎（COVID-19）兩種主要的確診方法。曾有報(bào)道，COVID-19病人咽拭子***核酸檢測(cè)出現(xiàn)連續(xù)三次或三次以上陰性的情況。臨床實(shí)踐中發(fā)現(xiàn)，咽拭子核酸檢測(cè)陰性的病人復(fù)查鼻拭子核酸檢測(cè)呈陽性，其原因可能是咽拭子和鼻拭子樣本不同，導(dǎo)致檢測(cè)結(jié)果存在偏差。下邊將為您解讀鼻拭子和咽拭子，以及它們?cè)贑OVID-19診斷上的應(yīng)用和區(qū)別。一、什么是鼻拭子？鼻拭子也稱鼻咽拭子，是提取鼻咽部上皮細(xì)胞和分泌物的取樣工具。鼻拭子提取的分泌物可進(jìn)行病原學(xué)檢測(cè)，如***核酸檢測(cè)、細(xì)菌培養(yǎng)等。常用于呼吸道***性疾病的診斷，如流感、化膿性鼻竇炎、鼻腔癤腫等。取樣方法為，用滅菌的鼻拭子深入到鼻腔內(nèi)，并到達(dá)鼻咽部通過旋轉(zhuǎn)或擦拭等方式提取分泌物和鼻咽部上皮細(xì)胞，然后將粘有分泌物的一段放入無菌容器內(nèi)，再進(jìn)行病原學(xué)檢測(cè)。二、什么是咽拭子？咽拭子是提取口咽部的黏膜細(xì)胞和分泌物的取樣工具。咽拭子提取的分泌物也可進(jìn)行病原學(xué)檢測(cè)，如細(xì)菌培養(yǎng)、***核酸檢測(cè)等。常用于包括咽部病變的呼吸道***性疾病的診斷，如流感、化膿性扁桃體炎、急性細(xì)菌性咽炎等。取樣方法為。深圳2019-nCoV鼻咽拭子湖南鼻咽拭子采購！</p><div

采集時(shí)醫(yī)務(wù)人員正面對(duì)著被采樣者口腔，有飛沫和氣溶膠傳染途徑的風(fēng)險(xiǎn)，取樣時(shí)間較短或力度不夠，很難采集足夠標(biāo)本，導(dǎo)致檢測(cè)假陰性出現(xiàn)。3.棉拭子與尼龍植絨拭子的區(qū)別采樣拭子的材質(zhì)、質(zhì)量對(duì)樣本質(zhì)量也很重要。尼龍植絨拭子上的絨毛，能增加拭子與咽部接觸的表面積，可以**大化地轉(zhuǎn)移細(xì)胞到拭子的表面。一項(xiàng)國(guó)外的研究發(fā)現(xiàn)，植絨拭子在轉(zhuǎn)移表面微生物的效率比棉拭子高20%～60%。4.站在患者側(cè)面的鼻拭子采樣，風(fēng)險(xiǎn)低于站在患者正面的咽拭子采集咽拭子標(biāo)本，需行三級(jí)防護(hù)，在采樣的過程中被采樣者可能因?yàn)檠什坎贿m會(huì)突然惡心、咳嗽等，造成飛沫飛濺。即便有些采集咽拭子標(biāo)本的工作場(chǎng)地被安排在室外，以保證有效通風(fēng)，但仍不能保證此項(xiàng)操作的高風(fēng)險(xiǎn)性。而鼻拭子采樣，可站在患者側(cè)面，并且避開了被患者敏感的咽反射的觸發(fā)（常表現(xiàn)為惡心反應(yīng)，嚴(yán)重者可出現(xiàn)嘔吐，其觸發(fā)區(qū)域?yàn)檠屎蟊?、舌根和雙側(cè)腭弓）。因此，規(guī)范鼻咽拭子、口咽拭子的操作程序，采用合格材質(zhì)的鼻咽拭子和口咽拭子，被采集人員做好配合等等，才能保證結(jié)果的可靠和準(zhǔn)確。下面就按照診療方案（試行第五版修正版）的要求，介紹采集同一患者鼻咽拭子、口咽拭子的流程。</p><p> 通?？上冗M(jìn)行鼻腔粘膜的表面麻醉和收縮，熟練的取樣者可以在不麻醉的情況下對(duì)患者取樣。由于鼻咽取樣時(shí)，操作者可以站在患者側(cè)后方操作，患者下拉口罩*露出鼻孔，遮住口腔，不需直視患者口腔，而且基本不出現(xiàn)咽反射，暴露風(fēng)險(xiǎn)相當(dāng)更低。個(gè)別患者取樣后可能出現(xiàn)噴嚏反射，也可以立即用手肘或紙巾遮擋。咽拭子核酸檢測(cè)標(biāo)本采集若操作不規(guī)范，可能造成“假陰性”的結(jié)果，導(dǎo)致患者延誤***。那么，咽拭子核酸檢測(cè)標(biāo)本采集的關(guān)鍵是什么？田鵬副主任醫(yī)師介紹，無論是采集鼻咽拭子還是口咽拭子，采集的深度和與黏膜接觸的時(shí)長(zhǎng)是關(guān)鍵。如果采集鼻咽拭子沒有采到鼻咽腔深處，采集口咽拭子時(shí)患者嘔吐反應(yīng)較大導(dǎo)致取樣時(shí)間不夠，這時(shí)可能采集到的細(xì)胞絕大部分都是不含***的細(xì)胞，即可能造成核酸檢測(cè)“假陰性”。有些患者核酸檢測(cè)陰性后“復(fù)陽”，有時(shí)與取樣不準(zhǔn)確有關(guān)。梁發(fā)雅表示，少部分患者可能在取樣后出現(xiàn)少許鼻出血，一般都可自行停止，必要時(shí)可用帶腎上腺素的棉簽稍微收縮一下出血部位止血即可。。黃岡鼻咽拭子廠家直銷！</p><div
