The U.S. Food and Drug Administration (FDA) has granted Emergency Use Authorization (EUA) for BD’s new molecular diagnostic test for both SARS-CoV-2 and Influenza A+B that can generate results in two to three hours. The new test also has been CE marked.
The test's instructions for use were updated to address SARS-CoV-2 variants, including those from the U.K. and South Africa. Computer analysis showed 99.9 percent of these variants’ genetic sequences are an identical match to at least one of the test’s two molecular targets1. This also applies to the standalone SARS-CoV-2 test for the BD MAX System.
The BD SARS-CoV-2/Flu assay is run on the BD MAX System and distinguishes between SARS-CoV-2 and Influenza A+B, providing a positive or negative result with a single specimen.
"The guidelines from the U.S. Centers for Disease Control and Prevention (CDC) recommend testing for both Flu and SARS-CoV-2 for all patients who are hospitalized and for patients who will not be hospitalized but for whom a positive result will change clinical management," said Dr. Charles K. Cooper, vice president of Medical and Scientific Affairs for Integrated Diagnostic Solutions at BD in a press release. "Since COVID-19 and Flu often present with similar symptoms, such as fever and dry cough, having a single specimen for accurate diagnosis speeds time to results and helps clinicians determine the right care more quickly to help prevent community transmission."
The BD SARS-CoV-2/Flu for BD MAX System kits can now be ordered in the U.S. and Europe. The test is the latest addition to the company's comprehensive COVID-19 diagnostics response. In October 2020, BD announced the CE mark for the CerTest Biotec VIASURE SARS-CoV-2 (N1 + N2) Real Time PCR Detection Kit, which allows BD MAX System users to combine as a single test the VIASURE Flu A, Flu B & Respiratory Syncytial Virus (RSV) Real Time PCR Detection Kit and report concurrently.
"Our diagnostic solutions for COVID-19 and Flu will help inform timely diagnosis and, ultimately, may contribute to faster and clinically appropriate patient management and treatment," said Dave Hickey, president of Life Sciences for BD. "In addition, the new information provided on the test's ability to detect the U.K. and South African variants provides helpful guidance to health care practitioners as we look to identify and contain these new strains."
This product has not been FDA cleared or approved, but has been authorized for emergency use by FDA under an EUA for use by authorized laboratories; this product has been authorized only for the detection of nucleic acid from SARS CoV-2, influenza A virus, and influenza B virus and not for any other viruses or pathogens.

1 The N1 and N2 primers and probes utilized for SARS-CoV-2 detection within the BD SARS-CoV-2/Flu for BD MAX System are identical in sequence to those reported in the CDC 2019-Novel Coronavirus (2019-nCoV) Real-Time RT-PCR Diagnostic Panel. An in silico comparison of the N1 and N2 primer sets was performed using all available high quality SARS-CoV-2 sequences submitted to the GISAID EpiCoV database6 by January 13, 2021 (n=329,434). Alignments against the N gene showed that both N1 and N2 primer/probe sets are a perfect match to 93.8 percent of sequences in the database, 96.8 percent of the sequences were a perfect match to the N1 primer set region, and 97.0 percent were a perfect match to the N2 primer set region. In total, 99.9 percent are a perfect match to either the N1 or the N2 region primer sets. The clinical performance has not been established in all circulating variants but is anticipated to be reflective of the prevalent variants in circulation at the time and location of the clinical evaluation. Performance at the time of testing may vary depending on the variants circulating, including newly emerging strains of SARS-CoV-2 and their prevalence, which change over time.
