Chemical safety and biosafety

Good Laboratory Practice (GLP)


The OECD Principles of Good Laboratory Practice (GLP) ensure the generation of high quality and reliable test data related to the safety of industrial chemical substances and preparations. The principles have been created in the context of harmonising testing procedures for the Mutual Acceptance of Data (MAD).

What's New

  • 19 April 2018 - Advisory Document of the Working Group on Good Laboratory Practice on the Management, Characterisation and Use of Test Items. This new Advisory Document provides clarity for test facilities on the expectations of national Good Laboratory Practice (GLP) compliance monitoring authorities regarding how test items are transported, received, identified, labelled, sampled, handled, stored, characterised, archived and disposed according to the Principles of OECD GLP. The document consolidates existing OECD guidance on test items that are used in studies conducted in compliance with the Principles of GLP. It also aims to promote a consistent approach that is appropriate to the objective of the study and the nature of the test item.
