After the implementation of the liberalization policy in various places, many nucleic acid testing points were cancelled. I have been able to complete the nucleic acid test in the past ten minutes, and now I have been waiting in line for two hours. Obviously, there are not enough nucleic acid detection points, which leads to slow detection results.
The substance of nucleic acid detection is the nucleic acid of virus. Nucleic acid detection is to determine whether COVID-19 is infected by detecting whether there is nucleic acid of foreign invasive virus in human respiratory tract samples, blood or feces. Therefore, once the nucleic acid is detected to be positive, it can be proved that there is a virus in the patient.
