From List to Impact: Operationalizing National Essential Diagnostics Lists
Diagnostics are the entry point to every health intervention - without diagnosis, there is no treatment.
Yet, access to diagnostics is as low as only 19% in low- and middle-income countries.
The gap is not a lack of knowledge about what tests are needed — it is the absence of systems to deliver them.
National Essential Diagnostics Lists (NEDLs) help countries define which tests should be available at different levels of care. The list alone does not guarantee that diagnostics become available, affordable, quality-assured, and used for decision-making.
WHO SEARO’s current operationalization work focuses on moving from policy lists to health-system implementation across governance, service delivery, procurement, quality management, monitoring, and digital/data systems.
WHO SEARO is developing a Regional NEDL Implementation Guidance Document — a practical, country-facing playbook connecting NEDLs with facility-wise test menus, procurement and supply planning, quality assurance, referral pathways, monitoring, and digital reporting.
