If the nucleic acid test result is negative, the health code will change from yellow code to green code. To remove the yellow code, we should not only do negative nucleic acid detection, but also observe it in time. During this period, the relevant departments will upload the results to the platform system, and wait for 24 hours before releasing the yellow code. If the yellow code is still not released, users need to report this problem to CDC for a solution.
In the case of the spread of nucleic acid detection, some areas of the city are divided into prevention areas and key places. If you have been to these places, many friends' health codes will turn yellow, that is, the health codes will turn yellow. If the health code is yellow, you will not only take the subway and bus, but also restrict access in many places.
How to do nucleic acid detection?
You should register your real name with your ID card, and then apply for nucleic acid testing at a fever clinic or a designated hospital. Nucleic acid detection is mainly through throat swab sampling. That is, use a soft cotton swab (a special collection tool for throat swab) to continuously rotate on the posterior pharyngeal wall and bilateral tonsils, put it into a test tube after obtaining obvious secretion, tighten the test tube cover, and then put the test tube into a sealed bag.
Keep the sealed sample tube at low temperature and send it for inspection as soon as possible.
