Good Laboratory Practice

Good Laboratory Practice (GLP) is a set of principles defined by Organisation for Economic Co-operation and Development (OECD) and implemented by national authorities. It provides a framework for how laboratory studies are planned, performed, monitored, recorded, reported and archived.

These principles ensure that studies producing data for assessing hazards and risks — whether to users, consumers, third parties, or the environment — are carried out in a consistent and reliable manner. GLP applies to areas such as preclinical pharmaceutical testing, agrochemicals, cosmetics, food and feed additives, contaminants, novel foods, biocides, and detergents.

By following GLP, laboratories demonstrate to regulatory authorities that the submitted data accurately reflect the results obtained during the study and can be relied upon for risk or safety assessments.
