G6PD Operational Research Community of Practice

By Diagnostics

Advancing the use of G6PD tests at the point of care

The G6PD Operational Research Community of Practice (GORCoP) is a collaboration of researchers, organizations, malaria control programs, and clinicians committed to advancing the introduction and scale-up of glucose-6-phosphate dehydrogenase (G6PD) diagnostics in support of safe access to radical cure treatment for Plasmodium vivax malaria through operations research. There are several G6PD diagnostics available now and in the pipeline that have the potential to expand access to safe radical cure. The GORCoP seeks to understand and prepare for the transitions that health systems will need to undergo to adopt these tests.

This community of practice aims to harness best practices and lessons learned from multiple stakeholders, benefiting from the expertise of participants in areas such as diagnostic introduction, operations research, implementation science, quality assurance, and training. To support information sharing, the GORCoP maintains a publicly available repository of resources accessible through the GORCoP website, hosts meetings and presentations, provides ongoing updates, and creates connections among participants.


The GORCoP offers resources and materials to support collaboration between national malaria control programs, researchers, and institutions working to advance the use of G6PD tests at the point of care. This includes sample protocols, test training materials, quality assurance and patient education materials, and archived webinars.

September 14, 2021 webinar: The validation and operational use of point-of-care G6PD testing in the Brazilian Amazon: a presentation of data from clinical study and real-life settings to inform test performance and considerations for use.

Stephanie Zobrist and Jose Diego Brito-Sousa presented data generated in two distinct research settings: a highly controlled clinical validation trial and municipal vivax malaria diagnostic units in the Amazonas and Rondônia states of Brazil. Their presentations will highlight key aspects of the performance and operational use in both settings, relevant distinctions, and discuss the implications of those differences for program planning and patient care.
