At the beginning of the pandemic, the only test available was a PCR test, which with an accuracy rate of 63 to 98 percent is still considered the "gold standard" of COVID testing. BD Veritor™ Plus System has a 98%-100% specificity, which means the false positive rate is less than 2% of all the tests performed. The problem is, these tests are more likely to miss active infection. There are no FDA-authorized, at-home antibody tests. There’s encouraging and not so encouraging news about COVID-19 testing. Experts generally agree that the RT-PCR tests are more accurate and useful than antigen and antibody tests, which are better used as confirmatory tools. BD… The objective of this study was to evaluate the performance of the BD Max enteric viral panel (Max EVP) assay for identification of viral pathogens in stool specimens from individuals with symptoms of acute gastroenteritis, enteritis, or colitis. “Never in my career have I seen anything like this, where the public is discussing and analyzing the data at the same time as the researchers,” she said. Confused about coronavirus testing? “Doing a full clinical trial takes a long time, but we need tests now,” said Sherry Dunbar, PhD, senior director of global scientific affairs for Luminex Corporation, which manufactures a pair of PRC tests and has submitted an application to the FDA for emergency approval of a new antigen test. "The BioGx molecular test for the BD MAX™ System and our recently announced serology test that can help detect current and past exposure to COVID-19 are part of BD's approach to give health care workers choice and access to the right test for the right situation," said Dave Hickey, president of Integrated Diagnostic Solutions for BD. False-negative results from antigen tests may range as high as 20 to 30 percent. BD Integrated Diagnostic Solutions president Dave Hickey: “The BioGx molecular test for the BD MAX System and our recently announced serology test that can help detect current and past exposure to Covid-19 are part of BD’s approach to give health care workers choice and access to … Testing is limited to laboratories certified … All products and services featured are selected by our editors. ... with certain COVID-19 tests from BD.

As with most other things regarding the novel coronavirus, pathologists and testing labs are learning about COVID-19 on the fly, said Dunbar. Find out how each test is performed and how accurate they are. Here's how COVID-19 can spread quickly and easily in bars, contributing to an increase in infections. False-positive results, while rare, can occur with PCR tests, said Wojewoda, because the coronavirus’ genetic material may linger in the body long after recovery from an infection. The BD Veritor™ Plus System for Rapid Detection of SARS-CoV-2 Assay is deemed to be a CLIA-waived immunoassay designed to be used in health care settings to provide an aid to rapid diagnosis of COVID-19 in symptomatic individuals. That has allowed novel coronavirus tests to quickly hit the market without the research and testing normally required for FDA approval.
