Why is the detection of nucleic acid No.6 abnormal in Circular No.9?

Lawless elements. Many criminals pretend to be "epidemic prevention and control office" to send short messages with abnormal nucleic acid test results to the public. The municipal anti-fraud center specially reminds you not to click on the link when you receive such information. Please delete it directly. If the detection of nucleic acid 6 is abnormal, it will be notified soon, not until the 9 th. After receiving the notice, we need to check the nucleic acid according to the arrangement of the staff, that is, sampling and re-examination. There is a certain probability that the abnormal result of nucleic acid is positive, so the abnormal result of nucleic acid will be isolated separately to ensure closed-loop management, and it can be determined whether it is true positive or false positive through re-examination. False positives may be caused by reagents used in nucleic acid sampling, nonstandard sample collection, sample storage errors, etc.
