China-based Joysbio (Tianjin) Biotechnology Co., Ltd. has developed a rapid test to diagnose the latest SARS-CoV-2 omicron subvariants BA.4 and BA.5. The Joysbio Coronavirus Antigen Rapid Test Kit, suitable for self-testing and requiring no professional support, can effectively detect these subvariants and has been certified by the Polish Centre for Testing and Certification (PCBC; CE1434).
Product Details and Certification
Joysbio states that the professional version of the test is already included in the “EU Common List of COVID-19 rapid antigen tests” under Category A. It is strongly recommended for use by the European Commission for the issuance of EU digital COVID certificates. The firm has already supplied over 200 million COVID antigen tests to markets around the world during the current pandemic.
Variant Background and Significance
The BA.4 and BA.5 variants were first discovered in South Africa and carry unique mutations, including changes in the viral spike protein. Scientists believe these changes mean even those with immunity to other COVID variants can be re-infected by BA.4/BA.5, highlighting the importance of effective diagnostic tools in managing the pandemic.-Fineline Info & Tech
