[Expert consensus on laboratory identification of emerging pathogens based on metagenomic next-generation sequencing technology(2025 edition)].

Emerging pathogen infections pose a significant challenge to global public health security. Pathogen metagenomic next-generation sequencing (mNGS), characterized by its hypothesis-free, culture-independent, and unbiased nature, provides a powerful tool for the timely detection and precise identification of emerging pathogens. This consensus was jointly developed by multidisciplinary experts from clinical laboratories, infectious diseases, disease prevention and control, and other relevant fields. It aims to standardize the identification process for clinically suspected emerging pathogen infections, as well as specimen submission, technical requirements, bioinformatic analysis, and reporting and interpretation procedures for the laboratory identification of emerging pathogens using clinical mNGS technology. This framework provides systematic guidance for clinical early warning and practice.
