Researchers at Caltech have developed a low-cost multiplex test that can rapidly provide three different types of data on COVID-19. The test can detect the presence of SARS-CoV-2, antibodies against the virus (potentially indicating a level of immunity), and inflammatory markers that could indicate the severity of COVID-19. Using blood or saliva, the test can provide a result in as little as 10 minutes. The researchers hope that it could soon be used by people at home to assess their COVID-19 status. Read More.
