Why didn't Beijing Xingyang receive the short message?

First, personal information is entered incorrectly; Second, there are many people who have been diagnosed recently, and the workload of nucleic acid testing is heavy. When the results are abnormal, a second re-inspection is needed immediately, and the re-inspection tube is still occupying the testing machine, resulting in the delay of other tubes. Third, in the case of positive mixed tube, in addition to waiting for the second re-examination, the relevant personnel also need to wait for the SMS notification from the CDC before they can carry out single tube nucleic acid. In addition, it failed to upload information on the registration platform in time, and it was impossible to continue using the sampled samples due to epidemic prevention, transportation and other reasons. It may also lead to the failure of nucleic acid results.
