Nearly 90% of study participants also had high levels of the virus in their bodies for at least a day before they received a positive result on their home COVID-19 test, the researchers found.
COVID-19 rapid antigen tests (RATs) have been widely used for diagnosis of COVID-19. The World Health Organization (WHO) COVID-19 Case Definition states that a person with a positive RAT (also known as an antigen rapid diagnostic test or Antigen-RDT) can be considered a "confirmed case of SARS-CoV-2 infection" in two ways.
