The study, conducted by the University of Toronto’s Rotman School of Management, was published in the JAMA peer-reviewed journal on Jan. 7, 2022. The researchers studied the results of roughly 900,000 rapid antigen tests taken in over 530 workplaces across Canada between Jan. 11 and Oct. 13, 2021.
During this period, the country experienced two major COVID-19 waves driven by the Delta variant, recording 1,322 positive rapid tests results, or 0.15 percent of the total tests. Among these positive cases, 1,103 patients were asked to take a polymerase chain reaction (PCR) test for further confirmation.
The study found that a total of 462 rapid test results were false, which represents 42 percent of the total 1,322 positive test results identified in the study, or 0.05 percent of the 900,000 results.
“These results inform the discussion of whether rapid antigen tests will result in too many false-positives that could overwhelm PCR testing capacity in other settings,” the researchers wrote.
They said their findings reflect the importance of having “a comprehensive data system to quickly identify potential issues,” though they also noted that the overall rate of the false-positive results compared to the total rapid antigen test screens was “very low.”
“With the ability to identify batch issues within 24 hours, workers could return to work, problematic test batches could be discarded, and the public health authorities and manufacturer could be informed,” they wrote.
Of the 462 false positive results, 278 (60 percent) were undertaken in two workplaces 675 kilometers apart by different companies between Sept. 25 and Oct. 8, 2021. The researchers said all of these false-positive test results were caused by a single batch of Abbott’s Panbio COVID-19 Ag Rapid Test Device, likely due to manufacturing issues rather than implementation.
The tests being administered too early or too late in the infectious stage, or the tests being done in an incorrect manner, were some of the reasons that could also contribute to the false-positive results, the study says."
