? The health code is green, but the scan code is yellow. What happened? How can the nucleic acid test be negative or yellow?

What happens when the health code is green but the scan code is yellow?

The health code is green, but the scanned place code turns yellow, which may be caused by poor communication signal and delayed mobile phone. I suggest you wait for a while before scanning or turning it off before turning it on.

The location code is the only two-dimensional code given to this important location by the platform. After scanning the place code, it will not only show the personal health status, but also show the location, name and other information of this important place. Generally speaking, the data of health code and place code are interoperable, so they are generally consistent.

Why is the nucleic acid test negative or yellow?

Please consider the following reasons:

1, the result of nucleic acid test hasn't come out yet: nucleic acid test needs to go through many steps such as sampling, extracting nucleic acid, testing and uploading the results, so it takes some time to get the results, but sometimes the time for nucleic acid test results to come out will be delayed if there are many people.

2. System update delay: If the health code or yellow code is considered to be a system or network problem after nucleic acid detection, you can quit refreshing and check again, or you can appeal to the import platform and provide relevant information before transcoding.

3. Abnormal nucleic acid test results: Generally, the yellow code can only be converted into green code after being tested twice every three days. However, if there is only one negative nucleic acid test result or one nucleic acid test result is abnormal for some reason, it will not be decoded, and the nucleic acid test needs to be carried out again. Only when the result is negative can the green code be converted.

I didn't go anywhere. Why did the health code turn yellow?

It may be judged by the disk as a space-time companion.

As an epidemic health code system, health code is located by residents' mobile phone numbers, based on actual real data, and generated by citizens or people who have returned to work through online self-declaration and background audit.

Under normal circumstances, residents' health codes will not turn yellow for no reason. If residents don't go anywhere, but the health code turns yellow, the main consideration at this time is to judge as a space-time companion. The so-called spatio-temporal companion mainly refers to staying together for 10 minute within 14 days in the same spatio-temporal grid as the diagnosed patient, usually taking 800 meters * 800 meters as the detection range. Generally speaking, the confirmed patient has been to a place within 14 days. If the person concerned crosses the diagnosed patient in the trajectory of 14 days, whether it is physical shoulder crossing or communication signal drifting, it may be considered as a space-time companion, and the health code will turn into a yellow code.

There are many reasons for residents' health code to turn yellow in life. If you still have questions, you can contact the epidemic prevention personnel in your area to ask. Yellow code doesn't mean infection. People with yellow code don't have to worry too much.
