If you want to change the health code back to the green code, you need to do nucleic acid testing. If you have completed the "two tests in three days", that is, you have done two nucleic acid tests, and the interval between the two tests is more than 72 hours, and the results are negative, then the yellow code will be automatically lifted. Therefore, it takes at least 3 days to recover the green code from the healthy code after the completion of nucleic acid detection.
