How is it that children's mixed nucleic acid test is suspicious and positive, but there is no SMS notification?

As the number of positive mixing tubes increases, the notification time is longer. Don't panic when you encounter mixed positive or abnormal situations. At the same time, due to the increase in the number of positive mixing tubes, the notification time is longer. People who find mixed positive need to take single-tube nucleic acid sampling at designated sampling points according to relevant regulations, try not to gather in public places, wait for single-tube results at home, actively contact the community after the results are negative, and travel normally after the health code returns to green code.
