[Introduction]: How long can Shanghai nucleic acid test results remain valid? Holding the nucleic acid test results of coronavirus within 7 days can be used as a basis for medical treatment. If the nucleic acid test exceeds 7 days, it needs to be tested again.
How long can Shanghai nucleic acid test results remain valid?
The validity period of the negative result of nucleic acid test of covid-19 is only 7 days, that is, if the nucleic acid test exceeds 7 days, it needs to be tested again.
The reason why effectiveness is limited to 7 days is mainly determined according to the incubation period rule of coronavirus. The incubation period of coronavirus is usually 3 to 7 days. In some cases, the incubation period is less than 3 days or more than 7 days, and the longest incubation period is 14 days.
The feasibility of actual operation is considered. The ideal validity period of negative nucleic acid test results is, of course, the shorter the setting, the safer. However, if it is too short, frequent detection is required, which is difficult to operate in reality, and 7 days is exactly the time with scientific operability.
