斯坦福医学院首创验血15秒测出是否有新冠抗体（图） | 美国华文网-圣地亚哥华文网-美国华人网-圣地亚哥华人-USChinesePress-SanDiegoChinesePress-ChineseMedia

科技救人！继上周湾区的Fremont出现首个不下车检测新冠病毒技术后，硅谷今日出现一项突破性成果 – 检测者不用下车，伸出个指头给一滴血，15秒钟即可测出检测者体内是否有新冠抗体。

只需要15秒就可以判断是否已有免疫，包括感染新冠的患者，和无症状感染者，然后可决定哪些人可以复工。这项由斯坦福大学医学院领导的全新测试方式已获得FDA授权。

美国疾病预防控制中心（CDC）发言人称，CDC已开始用其进行血液检查（testing blood）。圣克拉拉县上周有3200多人通过这个抗体检测方式，另外在加大旧金山分校也进行了测试。

血液测试只用等待15秒就能够判断一个人是否在血液中是否产生IgM和IgG抗体，不仅能确定是否感染，还能知道该患者可能已经感染并恢复。

这项研究的负责人之一，斯坦福医学院的Bendavid教授表示：如果可以证明患者有抗体保护，不会再被感染，那么被居家令留在家的人，就可能重新回到工作岗位。

CDC副理事乔布雷西（Joe Bresee）说：我们才刚刚开始进行测试，我们将很快就这些问题进行报告。我们认为血清研究对于了解社区真正感染的真正数量非常重要。

该项血液检查第一阶段将用于这些人群：

1.居住在新冠病毒加州、纽约、华盛顿州这样的高发区，还没有检测过的居民；

2.全国各地的代表性样本；

3.在一线的卫生保健工作者。

另外4月1日美国食品药品监督管理局（FDA）授予紧急授权的测试套件（emergency authorization）后已经开始。由Cellex公司开发的测试装备，和普通验血一样，刺一下手指，就可以在15秒内提供读数。针对全国人口进行检查的第二阶段可能会在今年夏天开始。这项突破性的检测方式，决定了各个城市禁令的走向。虽然不能绝对的说产生免疫系统的人就一定不会感染，但是如果有了免疫的人复工的风险会比较。大规模开展血液测试后，这样就可以判断预测接触居家隔离禁令和复工的时间。看完这些大家是不是觉得离出门的日子又进了一步，宅家隔离的日子总需要一点点盼头。
