Respiratory Panel Tests Flow from EUA Pipeline Ahead of Flu Season

The robust COVID-19 testing EUA pipeline has opened up a new opportunity for companies that produce multi-analyte panels capable of detecting not only the SARS-CoV-2 virus but other respiratory viral infections. And with the approach of flu season, half a dozen of these panel tests have reached the U.S. market with more to follow.

The New FDA Multi-analyte Testing Policy

As it customarily does, the FDA signaled its new policy of granting EUA to panel tests bundling SARS-CoV-2 with other respiratory viruses via informal guidance by posting a new Q&A to its website Questions & Answers for COVID-19 testing labs and test manufacturers. The new QA, which was posted on Sept. 9, notes “the overlap in signs and symptoms between SARS-CoV-2 and other respiratory viral infections, including influenza.” Multi-analyte panels capable of detecting and sorting out different viruses “are useful when multiple respiratory pathogens are circulated at the same time, as is expected with the upcoming flu season.”

The FDA also listed the factors it would consider in deciding whether to issue an EUA for such tests, including:

  • The extent to which the test aids differential diagnosis;
  • Whether the proposed use meets the requirements for the public health emergency declaration; and
  • The approval or clearance status of the individual tests within the panel.
Multi-Analyte Respiratory Panel Laboratory Tests with EUA Clearance
As of Sept. 29, the FDA has awarded EUA to the following multi-analyte respiratory panel tests:

  • QiaStat-Dx Respiratory SARS-CoV-2 Panel (Qiagen)
  • BioFire COVID-19 Test (BioFire Defense)
  • BioFire Respiratory Panel 2.1 (RP2.1) (BioFire Diagnostics)
  • Influenza SARS-CoV-2 (Flu SC2) Multiplex Assay (U.S. Centers for Disease Control and Prevention)
  • Cobas SARS-CoV-2 & Influenza A/B Nucleic Acid Test for use on Cobas Liat System (Roche)
  • Xpert Xpress SARS-CoV-2/Flu/RSV test (Cepheid)
