Microbix Launches Omicron Variant Test Control

Helping Ensure Workflow Accuracy of Tests for Respiratory Viruses

Mississauga, ON (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 a swab-formatted control that helps validate the accuracy and integrity of the workflows of nucleic-acid based tests (e.g., “PCR” tests) for SARS-CoV-2 (“COVID”) Wuhan strain and the Omicron variant (“Omicron”) – the latter now being the most prevalent form of COVID.

Specifically, Microbix is commercializing its In-Vitro Diagnostic (“IVD”) quality control to support workflow accuracy of clinical laboratory PCR tests that aim to detect and differentiate SARS-CoV-2 Wuhan strain and Omicron infections. This innovative, proprietary, and branded control provides a fully-compliant, comprehensive, and cost-effective quality management tool to help avoid the systemic errors that can be driven by technicians, consumables, or instruments. Users of this IVD control will include lab accreditation agencies, makers of tests oriented to clinical labs or point-of-care, and clinical labs or medical clinics.

This Microbix Omicron QAP is made using Copan® FLOQSwabs® – the optimal format for accuracy and point-of-care use, and with room-temperature stability for 12 months. As for all Microbix’s QAPs, this latest IVD control contains all possible PCR targets and is validated on multiple test platforms. This new QAPs SKU is labelled REDx™FLOQ® SARS-CoV-2 B.1.1.529 SWAB POSITIVE CONTROL and is now available to support clinical laboratory quality management systems (“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 over 70 proprietary SKUs in the categories of respiratory, sexually-transmitted, and gastrointestinal infectious diseases. Of that portfolio, 17 QAPs are available as REDx Controls for IVD use by clinical labs. In addition to QAPs to support PCR-based testing for the most important respiratory illnesses, including all major COVID variants, Microbix also has IVD QAPs to support antigen-based respiratory pathogen tests (e.g., 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 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 “For optimal patient care and public health management, clinicians and lab directors need controls that can provide them justifiable confidence in the accuracy and reliability of their testing programs. Microbix’s suite of QAPs to support testing for respiratory pathogens is providing that essential support, driven by our ability to quickly respond to the emergence of new viruses or variants with pandemic-generating potential. We are pleased to add this Omicron-oriented QAP to maintain our complete coverage of all major COVID variants.”
