FAQs about antigen self-testing for COVID-19

Can antigen self-testing replace nucleic acid testing?

No. Nucleic acid testing result is still essential to confirm the infection of novel coronavirus.

Antigen tests are generally used during the acute infection period, which means within 7 days of suspected COVID-19 cases showing symptoms. A nucleic acid testing is required for the suspected cases, regardless of their antigen test results.

What to do after testing positive from an antigen test?

People who have positive antigen test result should immediately report to local authorities regardless of having respiratory symptoms or fever. They will be transferred to designated medical facilities for nucleic acid tests.
