Microbix Presenting Test Validation Methods at AACC

MISSISSAUGA, Ontario, June 03, 2022 (GLOBE NEWSWIRE) -- Microbix Biosystems Inc. (TSX: MBX, OTCQX: MBXBF, Microbix®), a life sciences innovator, manufacturer, and exporter, announces it is presenting about the utility of its Quality Assessment Products (“QAPs™”) to monitor the end-to-end diagnostic process, including the impact of “preanalytical” sample-handling variables on test accuracy, at the 2022 “Preanalytical Phase Conference” of the American Association of Clinical Chemistry (“AACC”) taking place in Alexandria, Virginia from June 3-4, 2022.

Microbix is attending this AACC conference to present about these important aspects of infectious disease testing, alongside leaders in the global medical diagnostics industry. Microbix will also be conducting business development activities in relation to its expanding portfolio of QAPs, which includes Health Canada, U.S. FDA, EU “CE mark,” or TGA (Australia) in-vitro-diagnostic (“IVD”) regulated SKUs and research-use-only (“RUO”) designated SKUs across both liquid-vial and Copan FLOQSwab® formats.

Its poster presentation is titled “Simulated Swab Specimens for Whole Workflow Quality Control of SARS-CoV-2 Molecular Diagnostic Testing.” The poster details methods of using Microbix’s REDx™FLOQ® SARS-CoV-2 Swab Positive Control QAPs to assess the influence on patient-samples of hold-period durations of up to five (5) days, high temperatures of 35-40 °C, or a freeze-thaw cycle, relative to more optimal conditions. The study examined the effects of such conditions on the detectability of Microbix’s positive QAPs at full-strength and in 1:100 diluted form relative to strong-positive and weak-positive clinical specimens, using two different viral transport mediums (Microbix’s DxTM™ branded viral transport medium and another commercially-available brand) and two different Health Canada approved assays.

The results establish that the effects of sample storage and handling conditions can be accurately modeled using QAPs as proxies for clinical patient-samples. These Microbix products and methods can be used to validate processes for new-generation testing practices, such as at-home sample-collection, for a wide range of disease screening and diagnostic purposes, including COVID-19 and high-risk HPV infection, among others. The study was conducted in collaboration with FH Health Laboratory of Toronto, Ontario, whose support in sourcing clinical specimens, testing, and tabulation is gratefully acknowledged.
