China approves five COVID-19 antigen kits for self-testing - CCTV

China has granted approval to five COVID-19 antigen kits made by local companies to be used for self-testing, state broadcaster CCTV said on Saturday, as it tweaks its testing regime that has been pressured by Omicron. China's National Medical Products Administration (NMPA) published a notice saying Beijing Huaketai Biotechnology had been allowed to make changes to its COVID-19 antigen test kit's device certificate. It published a similar approval for four other companies, Nanjing Vazyme Biotech, Guangzhou Wondfo Biotech, Beijing Jinwofu Bioengineering Technology and a BGI Genomics subsidiary, Shenzhen Huada Yinyuan Pharmaceutical Technology, on Saturday.
