During the epidemic in novel coronavirus, nucleic acid detection was the most effective method to diagnose and screen COVID-19 infected people.
In some high-risk areas, in order to screen out COVID-19 infected people more accurately and avoid missed detection, it is generally necessary to do multiple whole-course nucleic acid tests, and some need to do nucleic acid tests every other day. Because COVID-19 nucleic acid test is prone to false negative, it needs multiple tests. Nucleic acid testing twice every three days means that after a nucleic acid test, it needs to be tested again every 24 hours and twice every three days. Some COVID-19-infected people also need to do nucleic acid tests twice every three days during the treatment to understand the recovery of the disease.
