MBX Microbix Biosystems Inc

Microbix Biosystems Inc. (TSX: MBX, OTCQX: MBXBF, Microbix®), a life sciences innovator, manufacturer, and exporter, announces that it is presenting results of a novel Quality Assessment Product (“QAP™”) for supporting Point-of-Care-Tests (“POCTs”) for infection with the Hepatitis C Virus (“HCV”) at the American Diagnostic and Laboratory Medicine (“ADLM”) conference taking place in Chicago, Illinois July 29 to August 1, 2024.

At ADLM, Microbix will exhibit alongside leading firms that provide tests to diagnose and direct treatment of HCV and many 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 ADLM, Microbix will present its poster titled “Novel Hepatitis C Virus External Quality Control that is Stable at Ambient Temperature and Suitable for Use in Low-Resource Settings.” The poster reviews the performance of a novel PROCEED®FLOQ® (RUO) QAP to support the training for and prospective quality management of POCT PCR tests that use fingerstick whole-blood samples to detect HCV. Following presentation of the poster on the afternoon of July 30, it will be made available at https://microbix.com.

In spite of efforts to eliminate viral hepatitis, it is estimated that 58 million individuals are infected with HCV. The majority of such persons live where conventional lab-based diagnostics are inaccessible due to high costs, want of equipment or trained personnel, or lack of “cold-chain” refrigeration. HCV POCTs are therefore critical for improving test accessibility, surveillance, and treatment, with such POCTs requiring suitably designed and robust External Quality Controls (e.g., QAPs) to monitor the accuracy of testing.

The novel Microbix HCV QAP is formatted onto a COPAN® FLOQSwab® to help achieve a consistent and accurate signal, provide room-temperature stability, and be superior to conventional HCV quality controls that must be kept frozen until use. The QAP is also whole-genome to contain all relevant PCR-test targets, works with the relevant sample-elution reagents, and has long-term stability at ambient temperatures (i.e., 2 to 30 ºC). This QAP is intended to facilitate and accelerate the rollout and adoption of POCTs for HCV, particularly for geographically or culturally-isolated persons and in low or middle-income countries.

Amer Alagic, Microbix’s Director of R&D and a co-author of the poster commented, “We believe this PROCEEDxFLOQ QAP is the first swab-based and room-temperature stable control for HCV POCTs. Our Microbix team is pleased to again be speeding-up the responsible rollout of tests for high-impact infectious diseases such as HCV and thereby reducing its individual and global health burden.”

Microbix gratefully acknowledges three external collaborators on this work, namely Flinders University (Australia), BioQControl (The Netherlands), and Cepheid Inc. (United States).
