University)的研究人员已获得美国政府批准，进行首次唾液测试，以帮助诊断COVID-19新冠病毒。这种新方法，有助于扩大测试范围，并降低医护人员感染的风险。</span></p><p><br /><span>新泽西大学(new Jersey university)在周一表示，美国食品和药物管理局(Food and Drug Administration，简称FDA)在其紧急权力下授权进行检测，以便迅速通过新的检测和治疗方法抗击疫情。这项测试最初将通过学校附属的医院和诊所进行。目前，美国各地社区仍在努力进行检测，以帮助追踪和控制冠状病毒。<br /><br />目前用于筛查COVID-19的方法要求医护人员从患者的鼻子或咽喉处提取拭子。为了降低感染风险，许多医院和诊所要求工作人员在与任何可能感染病毒的人密切接触后丢弃手套和口罩。许多医疗机构正面临基本医疗用品短缺的问题，包括手套、口罩和棉签。<br /><br />有了这种新的基于唾液的测试，病人将得到一个塑料试管，他们可以向里面吐几次唾沫，然后将试管交还给医护人员进行实验室处理。<br /><br />“这避免了医护人员不得不面对一个有症状的人，” 罗格斯大学实验室开发这项测试的负责人安德鲁布鲁克斯(Andrew Brooks)说。<br /><br />一名没有参与这项测试的传染病专家说，这将有助于减轻测试者的一些不适，并降低提取样本时遇到的困难。</span></p><p><br /></p></section><section powered-by="gulangu"><section><span></span><section><p><span><strong><span>2.对比测试结果乐观 准确率100%</span></strong></span><span></span></p></section></section></section><section><p><br /></p><p><span>约翰霍普金斯大学（Johns Hopkins University）的阿达尔贾（Amesh Adalja）博士说:“我们希望可以在各种情况下都有很多种选择，这样我们就可以以最合适的方式进行尽可能多的测试。”阿达尔贾指出，类似的唾液测试还有助于扩大艾滋病毒和其他疾病的检测范围。<br /><br />罗格斯通过采集60名患者的唾液和拭子样本来测试该方法的准确性，病人唾液样本的检测结果与拭子的结果100%吻合。<br /><br />罗格斯利用来自美国犹他州Spectrum Solutions公司的唾液收集工具，开发出了这种实验室测试方法。Spectrum Solutions公司为基于DNA的血统测试服务提供类似的设备。布鲁克斯说，罗格斯大学的实验室目前每天可以处理1万个病人样本。<br /><br />FDA在给罗格斯大学的授权信中说，这项测试应该只在“经过培训的医疗工作者监督下的医疗机构”进行。目前一些公司已经宣布将开始进行家庭测试的计划，但FDA还没有批准COVID-19在家庭中进行测试。<br /><br />此外，FDA表示，使用唾液试剂盒检测结果呈阴性的患者应该用第二种检测方法来确认他们的结果。</span></p><p><br /></p><p><span>4月13日，华盛顿大学宣布：所有入住港景（Harborview）医疗中心和华盛顿大学医疗中心的新病人都将接受新冠病毒的检测。这表明，随着测试方式的增加以及效率的提高，美国或即将展开大范围的新冠病毒测试。</span></p></section><p><br /></p><p><span>来源：<span>华人资讯网</span></span></p><p>
