Less-sensitive COVID-19 tests may still achieve optimal results if enough people tested, study finds: Analysis suggests same epidemiological outcomes possible with rapid-antigen versus RT-PCR tests

  • Different states in India use different mixes of two main tests for COVID-19: a very sensitive reverse-transcriptase polymerase-chain-reaction (RT-PCR) test and a less sensitive rapid antigen test.
  • Accounting for the movement of people between different locations, they calculated the total number of infections that would occur by the end of a pandemic under each scenario.
  • The authors also note that governments should continue to explore different mixes of tests that will yield the biggest reduction in the number of cases.
