新冠抗原检测试剂获批
COVID antigen tests approved China's top drug regulator has approved two antigen tests for COVID-19 that can produce results within 20 minutes, aimed at expediting management of suspected cases of the virus and boosting testing capacity. Antigen tests, which detect proteins on the surface of the virus, are considered cheaper and faster, but less accurate than the widely used nucleic acid tests, which look for genetic traces of the virus in samples. The newly approved tests, developed by Guangzhou Wondfo Biotech Co and Beijing Jinwofu Bioengineering Technology Co, are the first antigen tests for COVID-19 to be approved by the National Medical Products Administration, it said in a statement released on Thursday. The administration noted, however, that antigen tests alone cannot be used to confirm COVID-19 infection. "Antigen test results should be evaluated along with nucleic acid test results, CT imaging and epidemiologic history before making a diagnosis," it said. |
