As the SARS-COV-2 Omicron subvariants BA.4 and BA.5 make their way across the EU and the US, China-based Joysbio has developed Coronavirus Antigen Rapid Test Kit that can effectively detect these subvariants. The test is certified by CE1434 (PCBC) for self-testing by layperson.

The professional version of this test is recently included in the "EU Common List of COVID-19 rapid antigen tests" under Category A that is strongly recommended to use by the European Commission for the issuance of EU digital COVID certificates.

Back in June 2020, Joysbio released their breakthrough testing COVID-19 antigen rapid test. The 15-minute results allow government officials, event organizers, school officials, and others to make decisions about distancing, mask wearing, and other precautions. 

Since they released their first COVID-19 antigen test, JOYSBIO has supplied more than 200 million of tests around the world.
