UNDER-funded and inefficient diagnostic networks limit access to quality healthcare.

In low- and middle-income countries, basic diagnostic capacity is available in just 1% of primary care clinics and 14% of hospitals. Decision-makers struggle to expand access to these networks while improving efficiency and managing costs.

OptiDx is a web-based, open-access tool to conduct diagnostic network optimization (DNO) and route optimization analysis, for any disease. It enables countries to design diagnostic networks that align with national health goals and supports efforts towards universal health coverage.

enabling data-driven decisions for best network design

OptiDx uses national data to create a baseline network, or a digital model of the country’s current diagnostic network. It helps create various scenarios or alternative network designs, and compares them to identify a “best-fit” approach that can improve access, equity and cost-efficiency.


by reviewing the national or regional diagnostic network structure and performance, and identifying gaps and areas for improvement


by exploring various scenarios and suggesting best-fit solutions tailored to local contexts and priorities


by recommending the optimal frequency, mode and route for transporting samples from health facilities to laboratories


to achieve data-driven strategic planning and investments, through advanced network analytics that are

  • led by ministries of health in coordination with partners and easily updated as needed
  • backed by advanced technology, a standardized package of resource for quality practice and appropriate data security

OptiDx helps

  • weigh possible strategies and recommend solutions based on local contexts to strengthen diagnostic networks and expand access to testing
  • compare costs and outputs to shape investments for diagnostics systems strengthening
  • inform evidence-based strategic national plans and guidelines
  • evaluate the integration of new tests on existing devices
  • plan procurement or placement of new devices or the procurement of assays
  • guide funding requests
