How long does it take to check the yellow code twice every three days to turn green?

It will turn green in 72 hours at the earliest.

After moving and staying near the key places where the confirmed cases and asymptomatic infected people have stayed, and may have had contact with the confirmed cases and asymptomatic infected people, the health code will turn yellow, and the person assigned the yellow code needs to complete two tests in three days before it can turn back to the green code, that is, two nucleic acid tests have been done, and the interval between the two tests is more than 24 hours, and the results are all negative. The system will delete the yellow code and convert it to a green code.

Therefore, when the health code turns yellow and needs to be tested twice within three days after receiving the short message, you should avoid taking public transport, go to the nearest medical institution for nucleic acid testing within 12 hours after receiving the short message, test again 24 hours after sampling, and actively report the epidemiological history. If the test results are all negative, the health code will automatically return to the green code.

There is no reason for the nucleic acid to turn green after two times.

If a person with a yellow code or a red code does not turn into a green code after completing nucleic acid twice, it may be related to the following situations:

1. Too many people inquired about the health code, which delayed the system update. It is suggested to check the health code status later.

2. Personal information is incorrect, resulting in inaccurate nucleic acid results and misjudgment of health codes. You can change the code by providing corresponding information through the health code complaint platform. After the user submits the complaint request, if it meets the code change conditions, the system will generally complete the processing within 24 hours.

3. The nucleic acid test has been done, and the result is negative, but the yellow code has not been converted into green code, because the transcoding operation of health code involves the transmission of nucleic acid test data and the determination of provincial and municipal health codes, and there will be a delay in the middle. It is suggested to wait patiently, inquire again, and accept the third nucleic acid test if necessary.
