Briefly explained

Good Laboratory Practice (GLP)

According to the Organization for Economic Cooperation and Development (OECD), “Good Laboratory Practice (GLP) (...) is a quality assurance system that addresses the organizational process and framework under which non-clinical health and environmental safety testing is planned, conducted and monitored, as well as the recording, archiving and reporting of testing.”. GLP studies are, for example, an important component in the approval of plant protection products.

In Germany, the scope and type of monitoring of GLP are anchored in the Chemicals Act (paragraphs 19a to 19d). The Federal Institute for Risk Assessment (BfR) is responsible for the coordination and harmonization of GLP-relevant issues as well as the monitoring of certain GLP test facilities in Germany and abroad.
