Our First FDA Clearance: SimplicityDx™ Panel FluA/FluB/RSV

We're proud to announce that the U.S. Food and Drug Administration (FDA) has granted 510(k) clearance (K262789) for the SimplicityDx Panel FluA/FluB/RSV. It's Molecular Designs' first FDA-cleared assay and a milestone for our whole team.

About the SimplicityDx FluA/FluB/RSV Panel

The SimplicityDx Panel FluA/FluB/RSV is a multiplex real-time RT-PCR assay that qualitatively detects and differentiates influenza A, influenza B and respiratory syncytial virus (RSV) RNA in anterior nasal swab specimens from individuals with signs and symptoms of respiratory tract infection.

Influenza and RSV often circulate at the same time, and respiratory season can stretch lab capacity. Testing for all three viruses in a single run can help laboratories keep pace during those months. Results are intended as an aid in differential diagnosis, in conjunction with other clinical, epidemiologic and laboratory findings.

The panel includes influenza A, influenza B, RSV and an internal control. It is designed to work with Molecular Designs' SimplicityDx Extraction products.

Built around lab workflows

The panel's breakaway format is designed to let labs use only the assays needed for each run with minimal pipetting. This can help reduce waste and simplify inventory management, which is especially useful for labs with staffing constraints or volumes that swing with respiratory season. The format also supports batch processing for higher-volume days.

"Our goal was never just to add another respiratory assay," said Dr. Greer Massey, Chief Scientific Officer of Molecular Designs. "We set out to design one around how clinical labs actually work, with quality and efficiency as priorities from the start. Every choice, from the assay format to the run controls, came from working alongside lab teams and listening to what they need day to day."

A milestone for Molecular Designs

"This is a defining moment for Molecular Designs," said Michael Clark, CEO of Molecular Designs. "Earning FDA clearance requires rigorous manufacturing, robust quality systems and scientific discipline, and our team built all three. With respiratory season underway, we're ready to support labs with a cleared, practical way to test for flu A, flu B and RSV in a single run."

This clearance reflects work from every part of our company, and we're grateful to the people who made it happen.
