WHAT IS GLP?
Good Laboratory Practice (GLP) deals with the organization, process and conditions under which laboratory studies are planned, performed, monitored, recorded and reported. GLP practices are intended to promote the quality and validity of test data.
Published GLP regulations and guidelines have a significant impact on the daily operation of an analytical laboratory.
GLP is a regulation. It is not only good analytical practice. Good analytical practice is important, but it is not enough. For example, the laboratory must have a specific organizational structure and procedures to perform and document laboratory work. The objective is not only quality of data but also traceability and integrity of data. But the biggest difference between GLP and Non-GLP work is the type and amount of documentation.
For a GLP inspector it should be possible to look at the documentation and to easily find out
who has done a study,
how the experiment was carried out,-
which procedures have been used, and
whether there has been any problem and if so
how it has been solved.
The key requirements of a GLP type works are
Responsibilities should be defined for the sponsor management, for study management and for the quality assurance unit.
All routine work should follow written standard operating procedures.
Facilities such as laboratories should be large enough and have the right construction to ensure the integrity of a study, for example, to avoid cross contamination.
Test and control articles should have the right quality and instruments should be calibrated and well maintained
People should be trained or otherwise qualified for the job
Raw data and other data should be acquired, processed and archived to ensure integrity of data
The GLP requirements for proper planning, for controlled performance of techniques, for faithful recording of all observations, for appropriate monitoring of activities and for complete archiving of all raw data obtained, serve to eliminate many sources of error.
Whatever the industry targeted, GLP stresses the importance of the following main points:
1. Resources: Organisation, personnel, facilities and equipment;
2. Characterisation: Test items and test systems;
3. Rules: Protocols, standard operating procedures (SOPs);
4. Results: Raw data, final report and archives;
5. Quality Assurance: Independent monitoring of research processes.
