Scientists from several institutions in Guangzhou, China, have developed a new test that is similar to a pregnancy test, that detects antibodies against COVID-19
The WHO’s war cry against the novel coronavirus pandemic was “test, test, test.” Such is the importance of extensive testing in a rapidly worsening global health crisis where time is not money but life. In such a scenario, accurate and quick testing methods are essential for tackling the spread of COVID-19. Providing hope in this regard, researchers from China have developed a test that can detect antibodies against the SARS-CoV-2 virus in just 10 minutes.
The new test is a result of the collaboration between scientists from several institutions in Guangzhou, China, and builds on a testing technique known as a lateral flow immunoassay (LFA). An example of such a test is a home pregnancy test. It is based on the detection of the antibody, Immunoglobulin G (IgG), produced by the body to counter the coronavirus.
Expressing confidence over the new testing technique, the authors wrote in the study, “We expect this assay to be highly useful for helping to contain the COVID-19 outbreak by allowing timely diagnosis through early detection of SARS-CoV-2.”
