Following the first truly non-stop detection in Fremont in the Bay Area last week, there has been a breakthrough in the detection of Silicon Valley New Crown Virus recently.
This research project led by Stanford University School of Medicine canBlood tests for patients infected with new crowns, including those with asymptomatic infections, whether they are immune,To decide who can resume work.This new test method isThe first case in the United States, and has been authorized by the FDA.
A spokesman for the US Centers for Disease Control and Prevention (CDC) said that the CDC has started testing blood. Last week, more than 3200 people in Santa Clara County tested the COVID-19 antibody through a blood test.The San Francisco UCSF has also been tested.

Diagnosing Covid-19 infection through a blood test is very different from passing the commonly used nasopharyngeal swab test. The main advantages are as follows:
① Simple operation and good experience. Nasopharyngeal swabThe test is to take a sample from the back of the throat. The experience for the subject is very poor, and it is described as "like a needle piercing the brain". For blood tests, medical personnel only need a little blood at their fingertips.

② Blood test results onlyWait 15-20 minutes,Can determine whether a person produces IgM and IgG antibodies in the blood, not only can determine whether it is infected, but also knowThe patient may have been infected and recovered.
Professor Bendavid of Stanford Medical School, one of the heads of the study, said: If it can be proven that the patient is protected by antibodies and will not be infected again, then people who are staying at home by the "home order" may return to work.
However, many experts are uncertain about the "antibody". There is also support for big data after testing.
Joe Bresee, deputy director of the CDC, said: "We have just started testing and we will report on these issues soon." "We believe that serum research is very important to understand the true number of true infections in the community."
blood testThe first stageWill be used by these people:
1. Residents who have lived in high-risk areas such as New Crown Virus California, New York, and Washington State and have not yet been tested;
2. Representative samples across the country;
3. Health care workers in "front line fighting".

In addition, the test authorization (emergency authorization) granted by the US Food and Drug Administration (FDA) on April 4 has begun. The test equipment developed by Cellex, just like a normal blood test, can provide readings within 1 seconds with a finger prick. For the national populationThe second phase may begin this summer.
This breakthrough detection method determines the direction of the ban in various cities. Although it is impossible to say absolutely that people with immune systems will not be infected, the risk of resuming work if people with immunity will be compared. After conducting blood tests on a large scale, you can judge predictionsTime to contact the home segregation ban and return to work.
After reading these, do you think that the days when you leave the house go a step further, and the days of house isolation always need a little bit of hope.
