Abstract:
Pathogen genomics has transitioned rapidly from the research setting into a powerful tool now routinely used in public health microbiology, for surveillance, outbreak investigations and disease control. As these investigations can have significant public health, treatment and legal impacts, we must ensure the accuracy of these results through validation of testing processes. For laboratories working in this space, it is important to approach this work with a quality and accreditation framework in mind, working towards implementation of quality systems and test validation that meet international regulatory standards. Here we outline the key international standards and processes that lead toward accreditation for pathogen genomics.
Insights
Pathogen genomics is now a vital public health tool for disease surveillance and outbreak investigations. Ensuring accuracy through test validation and quality systems is crucial for reliable results and international accreditation.
Area of Science:
- Microbiology
- Genomics
- Public Health
Background:
- Pathogen genomics has evolved from a research tool to a routine public health application.
- Its use in surveillance, outbreak investigations, and disease control has significant implications.
Purpose of the Study:
- To outline key international standards and processes for laboratory accreditation in pathogen genomics.
- To emphasize the importance of quality systems and test validation for public health microbiology.
Main Methods:
- Review of international standards and regulatory frameworks relevant to diagnostic testing.
- Discussion of quality system implementation and test validation processes.
Main Results:

Infection
The chain begins with pathogens: bacteria, viruses, fungi, prions, or parasites such as protozoa helminths. These can be present on the skin as transient or resident flora, or they can be acquired from the environment. Identifying and treating the type of infection and...
