QAPs Supporting Molecular Diagnostic Tests for Dominant COVID-variant

MISSISSAUGA, CANADA, April 29, 2022 – Microbix Biosystems Inc. (TSX: MBX, OTCQX: MBXBF, Microbix®), a life sciences innovator, manufacturer, and exporter, announces it will present performance results of its Quality Assessment Products (“QAPs™”) supporting molecular-diagnostic tests for the Omicron variant of the SARS-CoV-2 virus (“Omicron”) at the 2022 Clinical Virology Symposium of the American Society for Microbiology (“CVS”) taking place in West Palm Beach, Florida from May 1-4, 2022.

At CVS, Microbix will be exhibiting alongside leading diagnostics firms that provide tests for detection of COVID and other infectious diseases. Microbix will also review performance of its QAPs to support quality management of testing for infection with Omicron (the B.1.1.529 variant of SARS-CoV-2).

Its poster presentation is titled “Use of SARS-CoV-2 Omicron External Controls for Verifying the Performance of Primary and Reflex SARS-CoV-2 Molecular Detection Methodologies.” The poster details the performance of Microbix’s Copan® FLOQSwab® formatted, room-temperature stable, and whole-genome Omicron-focused QAPs in challenging the accuracy of molecular (e.g., PCR-based) assays testing for mutations specific for this dominant variant and the generic tests designed to target only the wild type. The poster will be made available on Microbix’s website ( and from CVS following its presentation.

With over 50 reported mutations in its viral genome, Omicron can lead to reduced assay sensitivity or the outright inability of assays to detect it. Use of Microbix’s REDxFLOQ or PROCEEDxFLOQ QAPs offer whole-genome controls that contain all Omicron mutations and provide lot-to-lot consistency in order to optimally support clinical laboratories and test-makers in monitoring their assay performance.

Microbix now has QAPs to support tests for six (6) variants of the virus that causes COVID available for sale in Canada, Europe, the United States, and other commercially-important jurisdictions under its “REDx™” or “PROCEEDx™ brand names. Its QAPs support tests for the “Wuhan” strain, as well as those variants that have since become most prevalent, including the Alpha (B.1.1.7 or UK), Beta (B.1.351 or South African), Delta (B.1.617 or Indian), Gamma (P.1 or Brazilian), and Omicron (B.1.1.529 or Botswana).

Microbix is proud to be a strategic partner of Copan and offer a broad portfolio of infectious-disease oriented “PROCEED™FLOQ®” (RUO) and “REDx™FLOQ®” (IVD) QAPs to support testing programs worldwide.
