Becton Dickinson and Co.’s 15-minute COVID-19 test has been cleared for use in countries that accept Europe’s CE marking. In theory, the rapid “point-of-care” test meets an urgent need. There’s another problem. However, the reported accuracy of these rapid antigen tests is actually the percent positive agreement (PPA) and not sensitivity. o BD Veritor System • When compared with usual RT-PCR testing, the Quidel Sofia Antigen FIA showed a positive percent agreement (PPA) of 96.7% and a negative percent agreement (NPA) of 100%; the BD Veritor System showed a PPA of 84% and an NPA of 100%. BinaxNOW™ COVID-19 Ag Card Test & NAVICA™ App But a closer look at BD’s data reveals limits to the new test’s effectiveness. Of the seven discrepancies, PCR analysis agreed with the BD Veritor™ Plus system on five results and agreed with the Sofia 2 SARS AFI on two results. As part of its emergency use authorization (EUA) for the SARS-CoV-2 assay for the BD Veritor™ Plus system, BD completed one of the geographically broadest U.S. clinical trials of any antigen test on the market today, collecting and analyzing 226 samples from 21 diverse areas across the United States. “We are ramping up larger manufacturing capacities at the existing BD plant in Suzhou, China, as well as by a contract manufacturer in Massachusetts,” the company told The Daily Beast in a statement. Numerous universities rely on antigen testing to screen students in congregate living facilities and identify infectious individuals for isolation. Find out how each test is performed and how accurate they are. $125.00 Expedited RT-PCR COVID-19 Test (results within 12-24 hrs) This type of testing is the most accurate available to detect the SARS-CoV-2 virus.

Adjusting from the reported test performance to real-world diagnostic sensitivity shows that such decision makers could be substantially underestimating the number of missed infections. © 2020 Elsevier Ltd. All rights reserved. “Negative results should be treated as presumptive, do not rule out SARS-CoV-2 infection and should not be used as the sole basis for treatment or patient management decisions, including infection control decisions,” the FDA warned. University and school decisions about testing frequency and closing or isolation criteria often rely on risk tolerance for missing infections, the probabilities of which depend on test sensitivity. And that underscores how difficult it can be to quickly develop a coronavirus test that’s both fast and accurate. “We’re trying to make this something that’s not a whole lot more complicated than a pregnancy test,” Keith Jerome, a University of Washington virologist, told The Daily Beast in March. Policy optimisation and implementation requires an accurate understanding of testing sensitivity. You swab a patient, stick the sample in a vial containing a special cocktail of reagents, squirt the sample onto a plastic card then slip the card into a palm-sized test unit.

The U.S. Food and Drug Administration (FDA) maintains a list of in vitro diagnostic tests for COVID-19 that are approved under an Emergency Use Authorization (EUA). Note: Antigen tests can be used in a variety of testing strategies to respond to the coronavirus disease 2019 (COVID-19) pandemic. The FDA only approved the BD test for patients “who are suspected of COVID-19 by their healthcare provider within the first five days of the onset of symptoms.” And the only labs allowed to use the new test are those that the FDA previously authorized to use the Veritor system to detect other diseases. The PPA is measured relative to an RT-PCR test, which is imperfect itself. The BD Veritor ™ System for Rapid Detection of SARS-CoV-2 is a chromatographic immunoassay for the direct and qualitative detection of SARS-CoV-2 antigens in nasal swabs from patients with signs and symptoms who are suspected of COVID-19. FDA regulators issued a broad warning over potential false positive results from antigen test that return results in minutes. Poor sensitivity doomed an earlier, 13-minute coronavirus test from Chicago-based pharma Abbott Laboratories that the FDA approved for emergency use in March.
