QAPs Supporting Tests That Simultaneously Detect Multiple Respiratory Viruses

MISSISSAUGA, CANADA, April 19, 2022 – Microbix Biosystems Inc. (TSX: MBX, OTCQX: MBXBF, Microbix®), a life sciences innovator, manufacturer, and exporter, announces it will be presenting performance results of its quality assessment products (“QAPs™”) that support molecular-diagnostic (“MDx”) screening-tests for respiratory viruses at two industry congresses – “Labquality Days” in Helsinki, Finland April 20-21, 2022 and “ECCMID 2022” in Lisbon, Portugal, April 23-26, 2022.

Labquality Days is an annual international congress focusing on quality in laboratory medicine and medical devices. It is sponsored by Labquality Oy, a well-established Scandinavian clinical-lab proficiency and accreditation authority that is also a Microbix distribution partner. ECCMID 2022 is the 32nd annual congress organized by the European Society of Clinical Microbiology and Infectious Diseases.

At these events Microbix will be presenting performance results of its QAPs for support of MDx tests that detect multiple respiratory viruses from a single patient-sample. At Labquality Days, Microbix’s presentation is titled “Microbix’s Cross-Platform Compatible Respiratory Virus Multiplex Samples for use as a Quality Management Tool in Laboratory Syndromic Testing.” At ECCMID, Microbix’s presentation is titled “Respiratory Virus Multiplex Formulations Desiccated on Copan’s FLOQSwab® for use as Cross-Platform Compatible EQA Samples and Laboratory Quality Controls.” Microbix gratefully acknowledges the assistance of its six collaborator firms in planning and executing these evaluations. The posters will be available on Microbix’s website ( following their presentation.

The two poster presentations detail the performance of three Microbix “multiplex” QAPs that each support testing for three to four pathogens, collectively providing quality management support of testing for 11 common respiratory viruses – Adenovirus, Enterovirus, Influenza A, Influenza B, Metapneumovirus, Parainfluenza 2, Parainfluenza 3, Respiratory Syncytial Virus, Rhinovirus, SARS-CoV-2 (a.k.a., COVID-19), and Seasonal Coronavirus OC43. Each of these 11 viruses continue to cause widespread human disease.

These QAPs support the new-generation diagnostics that simultaneously detect multiple pathogens from a single patient sample – referred to as “multiplex” tests. By establishing the precise cause of disease symptoms, multiplex tests help enable better patient-care while also providing public health with intelligence on institutional or community prevalence of pathogens. Multiple new multiplex MDx tests are also suitable for use outside clinical laboratories – at point-of-care (“POC”) sites such as clinics or pharmacies – and thereby provide easier access to care and faster test results. Microbix “PROCEEDx™FLOQ®” and “REDx™FLOQ®” QAPs formatted onto Copan® FLOQSwabs® are ideal for supporting POC tests, as they fully-emulate test-workflows and are room-temperature stable.
