The GLI tool guides implementation of a quality management system in medical laboratories to get into compliance with the ISO 15189 standard. It is therefore highly recommended to purchase the ISO 15189 standard first, before starting the implementation of the Quality Management System. This standard should be used as reference for the requirements of the quality management system.

In this tool also references are made to the ISO 15190 standard for biosafety in medical laboratories. In order to implement biosafety adequately and according to the international standard it is also recommended to purchase this standard before continuing.

After familiarizing with both standards continue with phase 1.
