Health experts have been calling for expanded at-home testing to make it easier for people to determine whether they have COVID-19 and, if so, to avoid contact with others. However, it can take some time for manufacturing to scale up.
Most tests still require health professionals to perform a nasal swab, many of which are sent to labs for analysis. The FDA previously approved other tests that can deliver results in under 15 minutes.
Many airlines and countries require proof of a negative COVID-19 test before allowing travelers to fly or enter the country. Having the option to carry out a test at home with rapid results could make it easier for people to travel if they need to.
