What to do if a pooled PCR test yields a positive result
If a pooled sample testing for COVID-19 is positive, the people whose samples are involved will see their test results on the Suishenban App appear as 待复核, which means under verification.
Then they will receive a text message from the pandemic control authorities alerting them of the result and asking them to do an individual test ASAP.
People can go to a nearby testing site to take an individual test with the text message as a certificate.
Usually, 10 people's throat swab samples are mixed together and tested in a batch in order to improve efficiency.
