Nucleic acid detection is to monitor whether a person is infected with the new coronavirus at that time;
Detection of antigen, or detection of new coronavirus infection;
Antibody detection is to detect the amount of gamma globulin (IgG) present in a person's body after vaccination or infection, or the amount of antibodies against the new coronavirus, or even the amount of neutralizing antibodies that can specifically inhibit the new coronavirus
.
Nucleic acid detection is common all over the world
.
The significance of detecting antigens is controversial
.
Testing antibodies, there doesn't seem to be a lot of discussion
.
In fact, whether antibodies should be tested and what antibodies should be tested may now be seriously discussed
.
Collecting antibody data in a timely manner is very important during the COVID-19 pandemic
.
In the period when it was not popular, there was a lack of comparison of detection antibodies, and it was difficult to establish the relationship between the type of antibody, the amount of antibody and the efficiency of immunization and the rate of disease reduction
That is to say, after missing this opportunity, everyone is vaccinated.
Individuals do not know how many shots should be taken to be effective, because each person's reaction may be different.
Detecting antibodies may be the closest to detecting immunity and resistance.
.
Of course, if there is immunity other than antibodies, just looking at antibodies will not give a comprehensive response, but other immunity is not very well detected, and antibodies can not only be detected, but there is a certain possibility that antibodies are also related to other immunity.
Now, China has the ability to detect antibodies on a relatively large scale, especially IgG, and neutralizing antibodies can also be detected
.
The ability to detect different antibodies, throughput varies, but can reach a meaningful degree
Antibodies are detected, and the relationship between the amount of antibodies and the prevention of infection, and the amount of antibodies and alleviation of symptoms can be counted
By detecting antibodies multiple times, you can grasp the effective maintenance time after vaccination, and guide how long the vaccination should be
The above data can guide the vaccination of groups, and can also guide the vaccination of each individual
Having these data in hand will also be of great help to the national epidemic prevention policy
Whether it is insisting on clearing, or letting go, these data help
If you know a person's antibody status, and know what level of antibodies can prevent or alleviate symptoms, then people with sufficient levels of antibodies do not necessarily need to stay at home, but can consider working and living normally
If % of the population reaches sufficient antibody levels, it can be considered to release all
Using nucleic acid data, patients can be observed and tracked;
Using antibody data, if there is a reliable correlation conclusion, it is possible to predict health and predict mild disease, thereby benefiting individuals and helping countries
