MBX Microbix Biosystems Inc

Microbix Biosystems Inc. (TSX: MBX, OTCQX: MBXBF, Microbix®), a life sciences innovator, manufacturer, and exporter and Labquality Oy (Labquality), a global provider of laboratory external quality assessment (“EQA”) programs, announce their creation of the world’s first program to support accreditation of clinical laboratories for detecting the pathogens most commonly causing genital ulcer disease (“GUD”).

This novel Labquality EQA program will help ensure the proficiency of clinical labs testing to diagnose the pathogens that cause GUD. Initially, the program ascertains lab competency in detecting the four pathogens that are the most common causes of GUD – the organisms of Herpes Simplex 1 and 2 (HSV 1&2), Varicella Zoster (VZV/Chicken Pox), and Treponema pallidum (TP/Syphilis). As the clinical presentation of these infections can be similar, testing distinguishes between them to better direct treatment decisions. Other GUD pathogens, such as Mpox (Monkeypox), can be added to the program as-needed.

A Microbix fourplex quality assessment product (“QAP™”), formatted onto a Copan® FLOQSwab®, is used to establish the proficiency and accuracy of the GUD testing. In turn, Labquality has designed and is managing this GUD-oriented EQA program – which is now offered to labs in 60 countries.

The QAPs and EQA program were validated by way of a pilot-study that involved 18 clinical laboratories in 9 countries. In the EQA rounds performed thus far, the Microbix “PTDx™FLOQ® - HVT” QAPs were detected by 97% of the participants using tests across different instrument/assay platforms. Full results will be presented by Labquality or Microbix at an appropriate industry forum over the coming months.

Juha Wahlstedt, Sales Director at Labquality, commented, “We’re pleased to be employing Microbix’s innovative QAPs for this new and important EQA program. Genital ulcers are the cause of a considerable and growing burden of disease that can only be alleviated by way of accurate diagnosis and treatment.”

Pavel Zhelev, Director of Project Management at Microbix also commented, “We’re pleased to enable the creation of EQA for these clinically-important diseases. Our expertise was joined to that of Labquality and Copan to ensure accurate testing and properly-directed treatment is widely available for GUD patients.”

Canadian labs can enroll in this GUD EQA program (product code 5556) via R-Biopharm Clinical Canada at orders@r-biopharm.ca, international labs via their local Labquality distributor or info@labquality.fi, and enquires about Microbix QAPs can be directed to customer.service@microbix.com.
