The world has never encountered a strain of coronavirus, SARS-CoV-2, until the end of 2019. A new testing solution has been developed to diagnose the presence of the virus and it is being widely used. Positive results indicate the suspects are COVID-19 infected. Examination specimens could be collected by aural or nasal. Available tests included nucleic acid tests, antigen tests and antibodies tests. With increasing awareness of being infected, we could start seeing the self-administered test kit launched in the market.
