Can foreign ID card holders do nucleic acid testing if they live in different places in February?

It is completely possible to do nucleic acid testing in different places. Nucleic acid detection is not limited to a small area of a province, a city, a county, a community or a village.

Nucleic acid detection method: the substance of nucleic acid detection is the nucleic acid of virus. Nucleic acid detection is to determine whether the patient is infected by COVID-19 by detecting whether there is nucleic acid of foreign invasive virus in respiratory tract samples, blood or feces. Therefore, once the nucleic acid is "positive", it can prove that there is a virus in the patient.

After COVID-19 infects the human body, it will first reproduce in the respiratory system, so we can judge whether the human body is infected with the virus by detecting the virus nucleic acid in sputum and nasopharyngeal swab. Therefore, positive nucleic acid detection can be used as a new standard for the diagnosis of novel coronavirus infection.
