GLP (Good Laboratory Practice) is a formal regulation created by the FDA in 1978 to ensure the quality and integrity of safety data involved in regulatory decision making. It was developed because of cases of poor laboratory practices, fraudulent activities, and inaccurate reporting of studies. GLP principles provide a framework for planning, conducting, monitoring, recording, reporting and archiving laboratory studies according to standard operating procedures. Following GLP helps ensure the reliability and integrity of data, provides better control and guidelines for laboratory processes, and gives companies conducting research a quality image in the global market.
