Global laboratory systems development: needs and approaches.

Functional laboratory systems are a key component of country health care systems. Laboratory strengthening in resource-limited countries has been supported by disease-specific vertical programs that have focused on laboratory methods, procedures, and supplies for a country program, and providing training in performing tests. A health systems focus requires attention to regulations, management of national systems, national approaches to quality assurance, and education of laboratory scientists. An immediate focus of resources on the components required for a functioning system and continued technical support will enable countries to assume responsibility for their country-specific needs and improve their capability to address international responsibilities.
