TOKYO -- Japan hopes to test 400,000 people per week for the novel coronavirus, with the health ministry planning to approve the nation's first antigen test kit for COVID-19 on Wednesday.
Though antigen tests are less accurate than polymerase chain reaction testing, they offer results in about 15 minutes as opposed to hours. PCR testing is currently the primary method for detecting COVID-19 infections, but Japan hopes to bolster its testing regime by combining the two types.
