Early disease detection is crucial for improving health outcomes and offers significant economic benefits by addressing conditions before they become more complex and costly to treat. Unfortunately, diagnostics solutions are often the weakest link in the healthcare chain despite their important role. This project seeks to perform a landscape analysis to assess the status of diagnostics infrastructure in APEC economies. It aims to explore the role of diagnostics in strengthening the health system and the current gaps in infrastructure, accessibility, regulatory frameworks, and intergovernmental coordination. The study will also explore how real-time diagnostics can enhance rapid decision-making in clinical and public health responses. The project supports the 76th World Health Assembly's resolution on strengthening diagnostic capacities, which emphasizes equitable access to quality diagnostic tools for resilient healthcare systems. It will also consider the role of diagnostics in supporting regional and member economies’ disease control programs and priorities, particularly for high-burden diseases. The project will convene experts and stakeholders from APEC economies to evaluate their current capabilities and challenges in diagnostics adoption. The activities will include workshops, surveys, and a final report outlining recommendations.
