Should we use plastic bags to seal the door for nucleic acid testing at home?

No need. According to the relevant information about nucleic acid at home, we learned that there is no need to seal the door with a plastic bag for nucleic acid at home. There are two ways to collect nucleic acid at home:

1. The staff should provide comprehensive protection, and the staff will knock on doors door-to-door to collect.

2. The staff placed the nucleic acid collection materials at the door of their home. The residents took the nucleic acid collection materials back and put them back to the original place, and the staff took them away.
