What should I do if I don't check it in time after receiving the text message?

If you miss the time for nucleic acid testing, you can go to a hospital that provides 24-hour nucleic acid testing first.

If the relevant policy requires that the nucleic acid test cannot be carried out on the due date, it is enough to make up the test at the first time.

If the information such as health code is abnormal due to the lack of nucleic acid detection, such as yellow code, it can generally return to normal after the completion of supplementary detection and the uploading of nucleic acid detection results.
