ISO 25184:2026 PDF

Overview

ISO 25184:2026 - Molecular biomarker analysis - Nucleotide sequencing - Verified next generation sequences (VNGS) sets international requirements for reference nucleotide sequences generated by next generation sequencing (NGS) technologies. This standard ensures that verified next generation sequences (VNGS) are reliable, precise, and accessible in publicly or privately managed databases, and that they are usable on the semantic web for comparative genomics, molecular diagnostics, bioinformatics, and related scientific disciplines.

By providing structured requirements for VNGS, ISO 25184:2026 enhances sequence data quality, interoperability, annotation, and provenance, supporting the development and validation of molecular biomarker methods across biotechnology, food safety, clinical genomics, and life science research.

Key Topics

• VNGS Requirements: Defines platform-agnostic requirements for VNGS data, metadata, and use cases, including detection, identification, and quantification in diverse applications.
• Unique Identifiers and Versioning: Specifies a persistent and opaque URI scheme for VNGS, ensuring traceability and avoiding duplication or collision of sequence identifiers.
• Data Format and Machine Readability: Supports JSON, XML, and RDF for machine-readable data exchange, as well as version control practices for data and metadata.
• Semantic Interoperability and Ontology: Emphasizes the use of web ontologies (e.g., OWL, OBO Foundry) to ensure consistent knowledge representation and facilitate data integration across bioinformatics pipelines.
• Technical and Organizational Responsibilities: Outlines roles for reference sequence providers in establishing, maintaining, documenting, and updating VNGS, including ensuring format validation, data structure, annotation, and compatibility.
• Quality Metrics: Details essential sequencing quality indicators including base quality scores, coverage, GC content, N50/NG50 metrics, contamination removal, fragment size, and read depth.
• Minimum Metadata Requirements: Identifies mandatory annotation elements such as sample identifiers, organism metadata, sequencing and isolation details, and contact information to support data provenance and traceability.

Applications

ISO 25184:2026 enables a wide range of practical applications by providing harmonized reference standards for VNGS in:

• Comparative Genomics: Reliable VNGS facilitate the comparison of unknown sequences against reference genomes, essential in research and clinical diagnostics.
• Molecular Diagnostics: Standardized VNGS underpins accurate pathogen detection, strain identification, and surveillance in clinical and public health laboratories.
• Food Safety and Authenticity: Supports the verification and identification of foodborne pathogens and genetically modified organisms through high-quality sequencing data.
• Bioinformatic Pipelines: Ensures machine-readability, format validation, and interoperability, making VNGS ideal for automated pipelines in research and industry settings.
• Regulatory Compliance: Assists organizations in meeting traceability, annotation, and version control requirements for genomic data submissions.
• Data Sharing and Accessibility: By using semantic web standards and persistent URIs, VNGS are easier to share, find, and reuse across global scientific communities and regulatory bodies.

Related Standards

ISO 25184:2026 is part of a broader set of molecular biomarker and informatics standards. Key related standards include:

• ISO 16577: Vocabulary for molecular biomarker analytical methods in agriculture and food production.
• ISO/IEC 23092 series: Information technology standards for genomic data compression and representation (Parts 1-6).
• Official Methods of Analysis of AOAC INTERNATIONAL: Equivalent standard requirements for nucleotide sequences in biothreat agent detection.
• OBO Foundry/OWL: Ontology frameworks for knowledge representation in bioinformatics.

By aligning with ISO 25184:2026, laboratories and organizations benefit from international best practices in managing, validating, and utilizing NGS reference sequences, thereby supporting robust molecular biomarker analysis and fostering interoperability worldwide.
