Microbix Expands Pandemic Test Controls (QAPs™) Portfolio

Helping Ensure Workflow Accuracy of PCR Tests for COVID “Variants of Concern”

MISSISSAUGA, Ontario, Nov. 17, 2021 (GLOBE NEWSWIRE) — Microbix Biosystems Inc. (TSX: MBX, OTCQX: MBXBF, Microbix®), a life sciences innovator and exporter, announces the expansion of its portfolio of Quality Assessment Products (“QAPs™”) to include controls that support PCR tests for each of the four major variants of concern (“VOCs”) of the SARS-CoV-2 virus that is the cause of the COVID-19 pandemic.

Specifically, Microbix has developed, and is now commercializing, In-Vitro Diagnostic (“IVD”) quality controls to support workflow accuracy of clinical laboratory PCR tests for the Brazilian (P.1), Delta (B.1.617), South African (B.1.351), and UK (B.1.1.7) VOCs. These four VOCs are in addition to QAPs for the original Wuhan strain of the virus and are made using COPAN^® FLOQSwabs^® – the optimal format for accuracy and point-of-care use, plus room-temperature stability for 12 months. As for all Microbix’s QAPs, these VOC products contain all possible PCR targets and are validated on multiple test platforms.

These new QAPs are branded as a REDx™FLOQ^® SARS-CoV-2 P.1, B.1.617, B.1.351 or B.1.1.7 Swab Positive Control respectively and are available to support clinical laboratory quality management system (“QMS”) covering central lab and point-of care workflows in both the U.S. and Canada. Research-Use-Only (“RUO”) PROCEEDx^®FLOQ^® versions are now available for other markets, with REDx IVD versions to follow.

Microbix’s QAPs portfolio now consists of 70 proprietary SKUs in the categories of respiratory, sexually-transmitted, and gastrointestinal infectious diseases. Of that portfolio, 15 QAPs are available as REDx™ Controls for IVD use by clinical labs. Such Microbix REDx QAPs help manage the accuracy of workflows to avoid the systemic errors that result in false-negative or false-positive test results. Such errors occur and are consequential, as vividly demonstrated by the recent case of an estimated 43,000 false-negative COVID test results at a clinical lab doing COVID PCR testing on behalf of the UK’s National Health Service.

In addition to QAPs to support PCR testing for each of the most important COVID-19 strains, Microbix also has IVD QAPs to support COVID-19 antigen tests (REDxFLOQ SARS-CoV-2 Ag). Microbix’s QAPs for PCR-test and Antigen-test support are also available as ONBOARDx™ kits that include both positive and negative controls for convenient qualification of new instruments for clinical use and for the training of laboratory staff. This portfolio of COVID-oriented QAPs is in widespread use and can be paired with Microbix’s DxTM™ viral transport medium to enable collection and stabilization of patient test-sample specimens.

Cameron Groome, CEO and President of Microbix, commented “Microbix has been providing critical test ingredients to the diagnostics industry for over three decades. So it is our duty and privilege to apply that expertise to helping health authorities, clinical labs, test-makers, and lab accreditation agencies implement and conduct the widespread screening and diagnostic testing needed to mitigate the pandemic. I thank our staff, collaborators, suppliers, customers, and regulators for helping us to create these important new products and make them available to labs across Canada and the United States.”
