First of all, the test results are related to the level of detoxification. From infection to detoxification is a process. Detoxification level, detoxification time and detection time determine the accuracy of the detection results. Single nucleic acid detection is a time node in the whole process. If there is no detoxification at this time node, or the detoxification level is low, it may not be detected, and the potential infected person will not be detected. With the passage of time, the replication of the virus in the body will continue to increase, and the level of detoxification will be strengthened, so it is possible to become a positive infected person and there is a risk of spread in society, which is also the reason for doing a lot of tests. Find the infected person as soon as possible, and find and control it in time before it causes social spread or when the spread range is very small, so as to prevent the further spread of the disease.
Secondly, the current detection cannot be completely accurate at one time. The location of sampling, the time and depth of contact between throat swab and throat during sampling all affect the accuracy of sampling detection, which is also the reason why nucleic acid detection is needed for many times.
