The 10-person mixed nucleic acid test is generally used to test people in low-risk areas for novel coronavirus pneumonia, and the results are available on your cell phone the day after the nucleic acid test is done in the absence of special circumstances. 10-person mixed nucleic acid tests, in which 10 people are sampled separately with a throat swab and placed in the same collection tube, are performed. If the test result is positive, the 10 people will be isolated and tested again separately for nucleic acid to find the person who tested positive. If the test result is negative, all 10 individuals are considered free of novel coronavirus pneumonia. 10-person mixed nucleic acid testing can improve the efficiency of the test, which can now test 10 individuals in the time it takes to test one individual, allowing for faster detection of confirmed novel coronavirus pneumonia and protecting the health of the entire population. In addition, note that 10 people mixed test nucleic acid sampling within 2 hours before avoid eating, so as not to collect samples in the throat caused by the subject nausea, vomiting and other gastrointestinal discomfort symptoms. When waiting in line for testing should wear a good medical mask, maintain a distance of more than 1m, avoid crowding, reduce mutual conversation to prevent cross-infection. Immediately after the sampling should wash their hands or use alcohol, hand sanitizer, etc. disinfect hands, and leave the sampling crowded places as soon as possible.
