Accreditation Tools

Our contribution to high quality laboratory services

Laboratory Accreditation Tools

No laboratory should have to reinvent the wheel. Also not with implementation of a quality management system. So many laboratories have already succeeded. Why not learn from the experience of others?

GLI tool

DATOS and the GLI tool

In 2011 the GLI tool, fully called ‘Global Laboratory Initiative (GLI) Stepwise Implementation Towards Laboratory Accreditation’, was launched. This tool assists tuberculosis laboratories with implementation of an ISO 15189 quality management system and achieve accreditation. It is an online, free of charge tool that provides a stepwise plan for implementation of a quality management system. Where possible, the tool offers support materials, such as templates of Standard Operating Procedures and forms used in the laboratory, and background reading materials.

Our experts were the lead developers of this tool, which is the fruit of a consensus project in collaboration with partners, including the World Health Organization (WHO), U.S. Centers for Disease Control and Prevention (CDC), and the Clinical and Laboratory Standards Institute (CLSI).

DATOS and the LQSI tool

The GLI tool was received with so much enthusiasm that the World Health Organization requested our experts to develop a similar tool, but then for any type of medical/public health laboratory. This led to the development of the Laboratory Quality Stepwise Implementation (LQSI) tool.

The LQSI tool and GLI tool are nowadays widely used my numerous laboratories in low- and middle-income countries but also in high-income countries. A recent survey showed that the tools have guided many laboratories towards international ISO 15189 accreditation.

DATOS still maintains and improves the LQSI tool for the World Health Organization and contributed to the translation into Spanish, French, Russian, Arabic and Turkish.
