Recently, some netizens were tested for antibodies to the new crown virus after receiving the new crown vaccine, but the test results showed that no antibodies were produced in their bodies.
As we all know, whether antibodies are produced after vaccination is an important indicator to test whether the vaccine can work. The lack of antibody production has also raised concerns about whether the vaccine needs to be replenished.
In response to these questions, officials have repeatedly stated that it is not recommended for individuals to be tested for antibodies to the new crown, and that it is not necessary or feasible.
As early as January this year, Feng Zijian, deputy director of the National Center for Disease Control and Prevention, said that the vast majority of people can produce antibodies after vaccination, as proven by numerous clinical trials, but not all vaccines can produce 100% antibodies, which is related to inter-individual differences.
Virologist Chang Rongshan of Shantou University said that a negative antibody test after the required vaccination does not necessarily mean that the person did not produce antibodies, but it is related to many factors, such as the antibody test kit. Most of the current human antibody testing kits focus on naturally occurring antibodies, and may have false negatives for vaccine-generated antibodies.
In addition to performing antibody tests to determine whether they have developed antibodies to new crowns after vaccination, some people use new crown antibody tests to determine whether they are infected with new crowns.
Before vaccination, antibody testing can determine whether you have been infected with the New Coronavirus, but it cannot determine whether you are currently infected with the New Coronavirus, experts say: people who have been vaccinated and have been infected with New Coronavirus are not recommended to use antibody testing to determine whether they are infected. The Nucleic Acid Rapid Test remains the "gold standard" for diagnosing patients with neoplastic disease.
Why is the Nucleic Acid Rapid Test the "gold standard" for diagnosing NICs?
First, we need to know the principle of Nucleic Acid Rapid Test. Nucleic acid rapid test is to detect the specific nucleic acid fragment of the virus by PCR amplification method to increase the nucleic acid exponentially, and if there is nucleic acid fragment of neo-coronavirus, it will be fluorescently labeled to determine whether it has nucleic acid by fluorescence signal.
The PCR amplification method is an extremely sensitive way of experimentation, and generally accurate results can be obtained without contamination.
Secondly, the New Crown Nucleic Acid Rapid Test is more convenient than other currently accepted methods, eliminating the need for complex sampling and allowing for large scale and rapid sampling activities.
Most critically, New Coronavirus is a respiratory infectious disease, and in the early stages of infection, New Coronavirus is present on the epidermal cells of our upper respiratory tract. Because the virus is cryptic, other methods may not be able to determine it in the early stages of infection, but the New Coronavirus Rapid Nucleic Acid Test is able to confront the virus head-on and detect it in the early stages.
Finally, it is because the method of neostriatal nucleic acid rapid test for neostriatal virus has matured, and the accuracy and sensitivity and efficiency have been greatly improved by the optimization and upgrading of manufacturers, especially the launch of high efficiency amplification reagents and neostriatal nucleic acid rapid test system, which can meet the demand of rapid screening in multiple scenarios.
To sum up, the accuracy, sensitivity, convenience, adaptability, and various needs are all features that make New Crown Nucleic Acid Rapid Test the "gold standard". For individuals, the New Crown Nucleic Acid Rapid Test has been able to address most of the needs of individuals on the go, and antibody testing is not necessary for individuals if they are not judging treatment.
