Co-hosts Ana Navarro and Sunny Hostin were booted from Friday morning's live broadcast after returning the positive results at the eleventh hour.
The bombshell news caused chaos on the show's set and forced Harris to delay her interview, which was eventually conducted via video link from another room at ABC's New York studios.
But it has since emerged the results were both false positives after Navarro and Hostin tested negative in antigen and PCR tests taken as soon as they were whisked off air.
The co-hosts looked stunned as they received the news ahead of the highly-anticipated interview
The pair were dramatically ordered off set seconds before Harris walked out in front of a live audience, leaving producers scrambling
Navarro, who only co-hosts the show a few times a week, told CNN's Anderson Cooper on Friday night that she is 'tested weekly' and had tested negative after the broadcast.
'All of sudden it turned into an episode of Curb Your Enthusiasm,' she told Cooper.
She told Cooper she and Hostin were taken to their dressing rooms where they received an antigen and a PCR test and had to wait there until they got their results.
Navarro declined to reveal Hostin's results, but revealed her original test was a 'false positive.'
Hostin and Navarro had been sitting on stage alongside co-hosts Joy Behar and Sunny Hostin shortly after 10am Friday as they prepared to welcome Harris to their table.
But the introduction was dramatically interrupted by showrunner Teta, who yelled for Hostin and Navarro to leave the room, leaving Behar to explain to the audience what had happened.
'Sunny and Ana both apparently tested positive for COVID. No matter how hard we try, these things happen,' she stated.
'They probably have a breakthrough case and they will both be okay, I'm sure, because they are both vaccinated'.
Their sudden departure left Behar and Haines scrambling to fill air time. The pair spent several minutes taking viewer questions in scenes
