Mixing test tubes means putting several cotton swabs into the sampling test tube. 10: 1 mixed tube mixed sampling mixed detection is to improve the efficiency of large-scale nucleic acid detection in a short time, find potential infected people early and block the spread of the disease.
The personnel leaving the cabin can be mixed tube after three months, and the positive infected persons will not be included in the community mixed tube screening within three months after leaving the hospital and disembarking. According to this logic, three months after leaving the hospital, the nucleic acid password will be unlocked and the test tubes can be mixed.
There are two main reasons why the policy requires out-going personnel and key security personnel to be single-person. On the one hand, the mixed tube will dilute the specimen, which will lead to the missed inspection of abnormal personnel in key security industries. On the other hand, for those who leave the cabin, there may still be residual virus fragments in the body, and the test results may be positive. Although the virus is not active, it will affect others who are mixed.
In the name of key industry security personnel, they are all included in the single-person single-tube, not listed separately. As for when they entered the cabin, when they left the cabin, and whether there was a resurgence, this information needs time to trace, verify, count and enter. At present, the epidemic prevention situation is still relatively tense, and the pressure of flow regulation in various districts is still not small, so this part of the work has not yet started.
