At present, in order to detect novel coronavirus infection, it is necessary to carry out nucleic acid detection and antigen detection. The nucleic acid results are usually uploaded to the health code, which can show whether the patient is infected or not, but not in real time.
1, No nucleic acid test: If the patient is positive when he does antigen test himself, but does not do nucleic acid test, the health code will not be positive, so it is still green.
2. The system has not been updated: if the patient has both antigen test and nucleic acid test, the antigen test result will usually come out before the nucleic acid test result. After the patient knows that the antigen test result is positive, the health code may still be green, because it will take some time for the nucleic acid test result to come out and the health code will be updated.
3. Uploading error: Because the health code is identified according to the ID number, if the patient's result is positive when doing nucleic acid test and antigen test, but the staff uploads not the patient's own nucleic acid result, the health code will still be green.
