01 Improving diagnostics and surveillance  

From renovating clinical laboratories to building links between them, the Mérieux Foundation helps low- and middle-income countries to improve their diagnostic capabilities in order to promote universal access to high-quality diagnostics and build robust surveillance systems.  

From early screening to implementing appropriate treatment, patient follow-up, and preventing epidemics, laboratory diagnostics are at the heart of an efficient healthcare system. Strengthening clinical laboratories is a key focus of the Mérieux Foundation’s work and encompasses renovating or building infrastructure, training staff, and implementing surveillance systems and networks at both regional and national levels.

Training and the appropriation of expertise

Our approach is focused on the specific needs of each country and promotes laboratory autonomy through skills development: initial and continuing training is an essential component of all our projects. The Mérieux Foundation is one of eleven entities accredited by the Global Fund for laboratory capacity building.

Networking and sustainable governance

We promote networking as an essential factor in the performance of health systems and the development of coordinated responses to health emergencies. This involves providing support for the establishment of laboratory systems, strategies, and policies, with a view to building robust, sustainable governance.

The Foundation’s work in 2025 was significantly affected by political instability and conflicts in several areas where it operates. In each of the regions where we work, our teams had to adapt—sometimes urgently—to keep our projects on track, and several were scaled back. Wherever we are, we ensure the safety of our staff and partners while maintaining our commitment to beneficiary populations as far as possible.

In 2025, the Mérieux Foundation’s expertise in strengthening clinical biology laboratories was deployed across more than 30 projects in 25 countries
