Microbix Biosystems: presentation of data on respiratory virus controls at two events

MISSISSAUGA, CANADA, April 19, 2022 – Microbix Biosystems Inc. (TSX: MBX, OTCQX: MBXBF, Microbix®), a life sciences innovator, manufacturer and exporter, announces that it will present the performance results of its quality assessment products (“QAP™”) that support molecular diagnostics (“MDx“) Respiratory Virus Testing at Two Industry Conventions – “Laboratory Quality Days” in Helsinki, Finland on April 20 and 21, 2022 and “ECCMID 2022” in Lisbon, Portugal, from April 23 to 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 laboratory competence and accreditation authority that is also a Microbix distribution partner. ECCMID 2022 is on the 32n/a annual congress organized by the European Society of Clinical Microbiology and Infectious Diseases.

At these events, Microbix will present the performance results of its QAPs for supporting MDx assays that detect multiple respiratory viruses from a single patient sample. At Labquality Days, Microbix’s presentation is titled “Multi-platform compatible multiplex respiratory virus samples from Microbix for use as a quality management tool in syndromic laboratory testing.” At ECCMID, the presentation of Microbix is ​​called “Multiplex formulations of respiratory viruses dried on Copan’s FLOQSwab® for use as cross-platform compatible EQA samples and laboratory quality controls.“Microbix would like to thank its six collaborating firms for their assistance in planning and conducting these reviews. The posters will be available on the Microbix website (https://microbix.com) 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 testing quality management support for 11 common respiratory viruses – adenoviruses, enterovirus, influenza A, influenza B, metapneumovirus, parainfluenza 2, Parainfluenza 3, respiratory syncytial virus, rhinovirus, SARS-CoV-2 (aka COVID-19) and seasonal coronavirus OC43. Each of these 11 viruses continues to cause widespread human disease.

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