This document discusses Good Laboratory Practice (GLP), which are quality standards that regulate the conduct of non-clinical laboratory studies. It was created by the FDA in 1978 after investigations found fraudulent activities and poor practices in toxicology labs. GLP provides principles for planning, conducting, monitoring, recording, reporting and archiving laboratory studies according to standard operating procedures to ensure the quality and integrity of data. Non-compliance with GLP can result in the disqualification of a testing facility, rejection of study data, and civil or criminal penalties.
