Becton Dickinson (NYSE:BDX) is touting the results of a small, in-house study of its Veritor Plus antigen test over molecular (PCR) tests to indicate whether an infected person is more likely able to spread SARS-CoV-2.
The peer-reviewed study compared antigen and PCR test results to positive results using a viral cell culture test. Viral growth in the cell culture test indicates the presence of live virus in the patient sample, which may indicate the presence of infectious virus at the time the sample was taken. If no growth is present in the viral cell culture test, it is likely that there wasn’t enough viable virus for the patient to be contagious at the time the sample was taken, according to BD. The study was published in Clinical Infectious Diseases.
