If you miss a nucleic acid test, you can just go to the hospital or have a make-up test in the first place, and the display of relevant information will return to normal after the nucleic acid test results are uploaded. If you miss the time for the nucleic acid test, you can firstly go to a hospital that provides 24-hour nucleic acid test and have the nucleic acid test performed. If it is required by the relevant policy, the test should be failed on the date when the nucleic acid test is conducted, and a make-up test can be conducted in the first instance. If the health code or other information is displayed abnormally such as yellow code due to the failure of nucleic acid test, it can be restored to normal after the supplementary test is completed and the nucleic acid test result is uploaded. If you have missed the test and are unable to change the reporting time of the nucleic acid test to the same day, you can only make up the test in time, and you can consult with your local CDC department for the relevant policy.
