No notification message of nucleic acid detection was received.

Normal. I didn't receive the notification message or phone call. The results of nucleic acid test showed that the four-day green code was normal. The green code stands for "normal", even if it is a green code, personal protection is still needed. After nucleic acid detection, if the nucleic acid result is negative, the health code will be displayed in green; If the nucleic acid result is positive, the health code will be displayed in red, which needs to be reported immediately for subsequent processing.
