Good laboratory practices.pptx
- 2. Good laboratory practice is a quality system which intends to ensure, thorough, careful and accurate documentation covering all aspects of study and of its environment, the quality, integrity and reliability of safety data. The principles of good laboratory practice have been developed to promote the quality and validity of test data.
- 3. There are about three issues that are central to ideas behind GLP. They are: Continuation in testing. Accountability. Awareness. GLP is primarily intended to ensure data quality and integrity.
- 4. It makes sure that the data submitted are a true reflection of the results that are obtained during the study. GLP also makes sure that data is traceable. Promotes international acceptance of tests .
- 5. Industrial chemicals. Pharmaceuticals. Veterinary drug Pesticides, cosmetics Food additives preservatives Basic research Any laboratory procedure.
- 6. Availability of written documents availability of written procedures sops protocols Documentation in approved formats Regular quality checks Management commitment
- 7. Presence of appropriately trained and well organized laboratory staff. All laboratory personnel must receive direct and detailed job- specific training and continuing education to perform all duties so that they understand and completely carry out the necessary functions. competency assessments must be conducted every six months during the first year of employment, and annually thereafter. Annual evaluations for the employee’s overall performance of job responsibilities, duties, and tasks as outlined in the job description must be given to all laboratory personnel
- 8. The laboratory must employ an adequate number of qualified personnel to perform all of the functions associated with the volume and complexity of tasks and testing performed within the laboratory.
- 9. Approval or rejection of all raw materials, packaging materials. Evaluation of batch records. Ensuring validation or testing of analysts. Setting up a system of Quality Assurance. Preparing a quality control manual giving all details about systems to be followed.
- 10. The safety of all laboratory staff is paramount to avoid laboratory accidents that may jeopardize acquisition of infectious agents through handling of blood.
- 11. Safety policies defined according to regulatory organizations such as the Occupational Safety and Health Administration (OSHA) or the International Organization for Standardization (ISO) must be present in the laboratory. The following safety policies must be in place to ensure the safety of laboratory staff and any authorized individuals : Standard Precautions Universal Precautions Policy, Chemical Hygiene/Hazard Communication Plan, Waste Management Policy, Safety Equipment, and general safety policies .
- 12. Fire extinguishers, emergency shower, eye wash, and sharps containers must be present in each laboratory, in compliance with general safety/local laws. Periodic inspection and/or function checks of applicable safety equipment must be documented. Safety Training: the safety training must include : Blood borne pathogens, Chemical Hygiene/Hazard Communications, use of safety equipment in the laboratory, use of cryogenic chemicals (e.g., dry ice and liquid nitrogen), transportation of potentially infectious material, waste management/biohazard containment, and general safety/local laws related to safety. Safety training must be documented and maintained.
- 13. Safety incident reporting. Safety-related incidents must be documented, submitted, reviewed, and signed by the Laboratory Manager or designee on a regular basis, not to exceed one month from time of submission. Safety reports must be incorporated into the Quality Management (QM) program allowing the laboratory to note trends and correct problems to prevent recurrence.
- 14. Proper maintenance of all laboratory equipment is necessary for assays to function within manufacturer’s specifications. Internal preventative maintenance activities as well as vendor provided maintenance/repair for laboratory equipment is paramount in providing accurate and reliable results.
- 15. Laboratory staff must conduct preventive maintenance and service per manufacturer specifications by following documented daily, weekly, and/or monthly routine maintenance plans for all equipment utilized to ensure that all equipment performs consistently and reproducibly during the conduct of the trial. the laboratory must document all scheduled preventive maintenance, unscheduled maintenance, service records, and calibrations for all equipment utilized. This documentation should be readily accessible to operators .
- 16. The laboratory must establish tolerance limits for equipment temperatures and other monitored conditions (e.g., % CO2, liquid nitrogen levels) that are consistent with manufacturers’ guidelines and procedural activities because certain reagents and equipment perform optimally under specific conditions. The lab should also maintain daily (or “dates of use”) record of temperatures and other monitored conditions (e.g. humidity). For observations that fall outside of designated tolerance ranges, the laboratory must maintain appropriate documentation of corrective action for these out-of-range temperatures and other conditions.
- 17. Standard operating procedures (SOPs) are critical for maintaining consistent test performance. The laboratory must write SOPs for all laboratory activities to ensure the consistency, quality, and integrity of the generated data. They must be written in the standard formats. Current SOPs must be readily available in the work areas and accessible to testing personnel. All laboratory personnel must document and maintain verification that they have reviewed and understood all relevant SOPs so that there is evidence that all personnel are knowledgeable of appropriate laboratory SOPs .
- 18. The laboratory must maintain a written current document control plan that addresses and ensures the following vital elements of SOPs: A master list of SOPs currently used in the laboratory; an authorization process that is standard and consistent, limiting SOP approvals to laboratory management ; SOPs are procedurally accurate and relevant, as well as review of each SOP at appropriate time intervals ; removal of retired or obsolete SOPs from circulation and identification of them as retired or obsolete; and an archival system that allows for maintenance of retired or obsolete SOPs for a period defined by the laboratory that meets or exceeds the requirements of applicable regulatory bodies, such as the U.S. FDA.
