什么是抗原检测?它和核酸检测的区别在哪里?张文宏详解

According to the National Health and Health Commission website on March 11, the State Council issued a notice of the comprehensive group of the new type of coronary virus pneumonia. Plan (trial).

What is antigen detection? What is the difference from nucleic acid detection? Why should the state adopt antigen detection as supplement? Zhang Wenhong, the head of the Shanghai New Crown pneumonia clinical treatment expert and director of the Department of Infectious Department of Huashan Hospital affiliated to Fudan University, pointed out in an interview with the media that the antigen is like the clothes worn outside the virus, and the nucleic acid is the gene inside the virus.这两个检测略有不同,抗原的检测方法,是从抗体出发去测衣服,综合特异性之后,就可以让病毒显示出来;而核酸检测更为复杂,需要通过扩增来完成,因为有了In the amplification link, the sensitivity of nucleic acid detection will be higher, but the corresponding results will take longer.张文宏表示,在我们中国抗疫的第一阶段,我们通过核酸检测快速战斗实现清零,但最近大家也发现了,奥密克戎变异株出来后,整体上病毒传播速度在加快,不仅仅在上海,包括全国其他地方,不同地区出现比较多的病人,而且在短时间内病毒传播的速度很快。

At this time we will find that if the detection speed rely only on nucleic acid, there will be some difficulties. Zhang Wenhong said that because nucleic acids need to borrow machines, and sampling requirements and machine amplification have a very professional system. If there are inconvenient sampling or there is no suitable conditions for amplification, is there a simpler way? He said that as if the pregnancy test stick was pregnant, the antigen detection could be tested at home, and the speed was fast. In hospitals with poor conditions, the cost was also relatively low.

Why is this detection method so good, but everyone used to use nucleic acid to detect it? Zhang Wenhong explained that everything has its two sides. Because the antigen detection has not expanded, the sensitivity should be slightly lower, but once the positive is detected, it will have strong value. The antigen detection was adopted during the Hong Kong resistance. The institutions involved in the anti -epidemic also recognized this test method. It can directly declare whether the new crown is infected through the antigen detection, and then take a series of measures. Zhang Wenhong further stated that in the future, if we want to face the input cases brought about after a larger scale of international opening up, we must always control this virus to a very low level of transmission, that is, we compare with the virus time. The case discovers the case discovery of the case. The earlier, the less spread, the faster the speed of our isolation, then we can finally achieve the clear zero of society at a faster speed.

Zhang Wenhong said that in the first stage of our Chinese anti -epidemic, we achieved clear zero through nucleic acid testing, but recently everyone also discovered that after Omikon’s mutant plant came out, the overall virus spread was accelerating, not just not just, not only In Shanghai, there are more patients in different regions, including other parts of the country, and the virus spreads quickly in a short period of time. At this time we will find that if the detection speed rely only on nucleic acid, there will be some difficulties.
