ABSTRACT
Scaling molecular diagnostic facilities is essential for meeting growing demands for infectious disease surveillance, oncology, genetic screening, and precision medicine, particularly across resource-constrained and rapidly expanding health systems. This study examines how standardized infrastructure and operational design models can enable scalable, high-quality molecular diagnostics while ensuring biosafety, regulatory compliance, and cost efficiency. It synthesizes insights from laboratory engineering, health systems planning, and diagnostic network design to propose an integrated approach to molecular facility expansion. Standardized infrastructure models emphasize modular laboratory layouts, flexible cleanroom zoning, validated airflow and contamination control systems, and harmonized utilities for power, water, and waste management. These design principles enable rapid replication, phased expansion, and adaptability to evolving assay technologies without compromising analytical integrity. Operational design models complement physical standardization through optimized workflow sequencing, sample logistics, equipment utilization, and quality management systems aligned with international laboratory standards. Together, these models reduce setup time, minimize variability, and support consistent performance across decentralized molecular testing sites. The study further highlights the role of digital enablement in scaling molecular diagnostics, including laboratory information management systems, remote monitoring platforms, and standardized data architectures that support traceability, quality assurance, and network-level oversight. Workforce-aligned operational models, incorporating task differentiation, competency-based training, and remote supervision, are identified as critical to sustaining performance in settings with limited specialist capacity. Financing and governance mechanisms, including pooled procurement, regional laboratory networks, and public–private partnerships, are discussed as enablers of affordability and long-term sustainability. The study concludes that scalable molecular diagnostic capacity depends on the integration of standardized infrastructure with adaptive operational design. By embedding flexibility, quality assurance, and interoperability into facility and workflow models, health systems can rapidly expand molecular testing while maintaining safety, reliability, and regulatory alignment. Such approaches strengthen outbreak preparedness, support routine disease management, and advance equitable access to advanced diagnostics across diverse healthcare contexts. Importantly, standardization does not constrain innovation but provides a stable platform for continuous technological evolution, network optimization, and resilient diagnostic system growth in low-, middle-, and high-income settings globally. These frameworks also facilitate benchmarking, performance comparison, regulatory audits, and coordinated scale-up across national, regional, and cross-border diagnostic ecosystems worldwide.
