Mike DeWine of Ohio, who last week tested positive for the coronavirus, then negative and then negative again, said on CNN on Sunday that his roller-coaster ride should not be reason for people to think “that testing is not reliable or doesn’t work.”His first test result was positive, when he was screened with a rapid testing method on Thursday before President Trump arrived in Ohio for campaign appearances. Mr. DeWine was given an antigen test made by Quidel, one of two companies that have received emergency use authorization from the Food and Drug Administration for coronavirus antigen tests. These tests, while fast and convenient, are known to be less accurate than PCR tests, which were used to retest Mr. DeWine twice on Thursday and once more on Saturday. All three PCR tests turned up negative, confirming that Mr. DeWine was not infected with the virus.
