What does it mean to receive a text message saying that the nucleic acid sample is damaged?

The news that the nucleic acid sample is missing means that the nucleic acid test has not been completed. Comprehensive detection of nucleic acid is a screening method for risk areas, which can find infected people as soon as possible, and then take corresponding measures as soon as possible to avoid the spread of the epidemic in a wider range. For those who do less nucleic acid testing, it is suggested to report to the community in time to see if they can make up for it, or go to a third-party nucleic acid testing institution or medical institution for nucleic acid testing as appropriate.
