| Officials at SD Biosensor check COVID-19 self-test kits developed by the company, at its factory in Osong, North Chungcheong Province, Thursday, before they are sent to pharmacies or online sellers. The kits received conditional approval for use from the authorities last week. People can collect samples from their noses with the kits, and see the results of the test within 15 to 20 minutes.
