DiaSorin Molecular LLC (Cypress, CA, USA) has received FDA Clearance for its Simplexa Flu A/B & RSV Direct Gen II kit that can be run alone or alongside the Simplexa COVID-19 Direct kit, allowing for differential diagnosis of SARS-CoV-2, influenza A (Flu A), influenza B (Flu B), and respiratory syncytial virus (RSV).

The upcoming 2020/2021 flu season will be complicated by the presence of SARS-CoV-2 also circulating in the community. Viral infections caused by Flu A, Flu B, RSV and SARS-CoV-2 have similar clinical presentations, however treatment options are different and thus it is important to differentiate. Additionally, co-infection with SARS-CoV-2 and Flu A or B has been shown to cause increased severity of respiratory disease and the need for a combination therapy. The accurate diagnosis of the virus causing the infection can have major implications for the management of therapeutic regimens, infection control and community mitigation efforts.

DiaSorin’s latest generation Simplexa Flu A/B & RSV Direct Gen II kit delivers continued comprehensive strain coverage and accurate detection in an efficient and trusted sample-to-answer format that does not require extraction. Collectively, over 100 Flu A, Flu B and RSV strains have been validated, including the 2020/2021 influenza vaccine strains. The Simplexa Flu A/B & RSV Direct Gen II assay is designed for use with the LIAISON MDX instrument.

“With COVID-19 set to play a major role in the upcoming flu season, it was critical for us to have the Simplexa Flu A/B & RSV Direct Gen II assay available in time for patient samples to be tested, when needed, alongside the Simplexa COVID-19 Direct assay,” said Michelle Tabb, chief scientific officer of DiaSorin Molecular. “Detection and differential diagnosis between influenza, RSV and COVID-19 will be vital this year and we are pleased to contribute to this solution.
