Microbix Presents Results of STI Test Controls at AACC

FLOQSwab-formatted QAPs Supporting Fourplex PCR Tests for Bacterial STIs

MISSISSAUGA, Ontario, July 24, 2023 (GLOBE NEWSWIRE) -- Microbix Biosystems Inc. (TSX: MBX, OTCQX: MBXBF, Microbix®), a life sciences innovator, manufacturer, and exporter, announces that it is presenting results of its Quality Assessment Products (“QAPs™”) for supporting the clinical use and accuracy of multiplex tests for four of the most prevalent sexually-transmitted infections (“STIs”) at the American Association of Clinical Chemistry (“AACC”) conference taking place in Anaheim, California July 23 to 27, 2023.

At AACC, Microbix will exhibit alongside leading firms that provide tests to diagnose and direct treatment of STIs and other infectious diseases. Microbix will thereby showcase its ever-growing portfolio of QAPs that help ensure the accuracy of antigen and molecular (i.e., “PCR”) tests and their workflows.

Also at AACC, Microbix will present a poster titled “Evaluating the Performance of Emerging STI Point of Care Assays Using Novel, Room Temperature Stable CT/NG/TV/MG Positive Swab Quality Control Materials.” The poster reviews the performance of novel PROCEED®FLOQ® (RUO) QAPs to support the clinical use and accuracy of multiplex PCR tests for Chlamydia trachomatis (CT), Neisseria gonorrhoeae (NG), Trichomonas vaginalis (TV), and Mycoplasma genitalium (MG) – four of the most prevalent STIs. The poster can be read at https://microbix.com and a REDx®FLOQ® (IVD) product format is also available.

Point of Care Tests (“PoCTs”) that can distinguish between STI-causing pathogens promise improved access to care and faster turnaround time from patient-sampling to test-result. However, users of such PoCTs must have accurate and robust test-control materials for quality management purposes. Microbix therefore developed a whole-workflow multiplex STI QAP desiccated on a Copan FLOQSwab® that is stable at 2-30°C and contains inactive whole-genome target pathogens. The poster evaluated its performance with multiple diagnostic platforms in current use and in development, namely the Abbott Alinity™ m STI assay, Aprimeo/Bosch Vivalytic™ STI Assay, BD MAX™ CT/GC/TV assay, Cepheid Xpert® CT/NG and TV assays, Seegene Novaplex™ CT/NG/TV/MG assay, an IVD assay in late-stage development, and a lab-developed assay.

Dr. Amer Alagic, an author of the poster and Director of R&D at Microbix, commented prior to his presentation of the poster at AACC “Microbix’s whole-genome and room-temperature stable FLOQSwab-formatted QAPs continue to demonstrate their ability to support quality management on a wide range of molecular assays and instrument platforms. We’re pleased to be offering Microbix QAPs to support clinically-important STI testing – as tools for validation, verification, and training, as external quality assessment samples, and as in-kit controls.”
