In Reply In response to the request by Dr Bezerra for additional details about the COVID-19 tests used in our study, there were 1322 presumptive positive results out of 903 408 rapid antigen tests. Of these, 92 504 were performed using BD Veritor tests (which had 125 presumptive positive results) and 810 904 using Abbott Panbio tests (which had 1197 presumptive positive results). Of the 462 presumptive positive results that were false-positives, 278 came from the same lot of Panbio rapid antigen tests that were used at 2 workplaces separated by a distance of 675 km.
