The trouble with testing
The fast-test kit, also known as the Elisa test, is a blood test checking antibody levels, which determine whether you have been infected with the coronavirus and your body developed antibodies to fight it. So the Elisa test is best for those who returned home between July 1 and 14. Those who were in Đà Nẵng after the 14th need to wait a little longer for any antibodies to be produced.
Many doctors have gone on social media to warn people about properly understanding negative Elisa test results, saying they should still self-quarantine for 14 days to protect themselves and those close to them.
The RT-PCR test has proven to be the most accurate way of detecting COVID-19 currently available.
