The document outlines the principles of Good Laboratory Practice (GLP) established by the OECD in 1981, aimed at ensuring the integrity of non-clinical health and environmental safety studies. GLP was created in response to unethical practices in laboratories, promoting trust, high quality data, and international acceptance while also highlighting the need for adequate personnel, equipment, and quality assurance. The document details specific requirements for personnel, study protocols, animal housing, facilities, and documentation to maintain compliance with GLP standards.

1. Good Laboratory Practice (GLP)

2. Scope of GLP
In 1981an organization named OECD (Organization for
Economic Cooperation and Development) produced GLP
principles that are international standards.
GLP in OECD principles is defined as “a quality system
concerned with the organizational process and the conditions
under which non-clinical health and environmental safety
studies are planned, performed, monitored, recorded,
archived and reported”.

3. Why GLP was created?
1) GLPs were initially invoked in a reaction to malpractices in the
laboratories conducting safety
experiments of medicines.
2) in the early 1970s, research laboratories in the USA found doing
work in unethical ways, like
• Data generation without conduct of the study.
•Falsification of the laboratory work.
•Replacement of dead animals and fabrication of test results etc
therefore GLP was created to Minimize this

4. Advantages of GLP
• Assures that the data are a true reflection of results
obtained from studies.
• Preclinical safety and residue safety.
• Generation of high quality and reliable test data.
•Mutual acceptance of data
•Increases public confidence.
•Shortens the time-to-market for new products.

5. Disadvantages of GLP
• More man power is required.
•Expensive process.
•Time consuming process.
Objectives of GLP
1) GLP mates sure that the data submitted are true reflection of the
results obtained from the studies.
2) GLP makes sure that the data is traceable.
3) Promotes international acceptance of tests.

6. 1. Personnel
 Each individual engaged in the conduct of or responsible for the supervision of
a non-clinical laboratory study shall have education, training, and experience
 There shall be a sufficient number of personnel for the timely and proper
conduct of the study according to the protocol.
 Personnel shall take necessary personal sanitation and health precautions
designed to avoid contamination of test and control articles systems.
 Personnel engaged in a non—clinical laboratory study shall wear clothing
appropriate for the duties they perform.
 Any individual found at any time to have an illness that may adversely affect
the quality and integrity of the non-clinical laboratory study shall be excluded
from direct contact with test systems, test and control articles

7. 2. Equipment
 Appropriate design and adequate capacity.
 Equipment shall be adequately inspected, cleaned and
maintained.
 Equipment used for generation, measurement or
assessment of data shall be adequately tested,
 calibrated and standardized.
 Log books for each equipment should be there.

8. 3. Quality Assurance Unit
 An individual or a group designated by management to assure that the studies s in
compliance with GLP principles.
 Monitors the study to assure management that the facilities. equipment, personnel, methods,
 practices, records and controls are in conformance with the regulations.
 Maintain the copies of master schedule sheet, protocol and SOPs.
 Access to updated study plans and SOPs.
 Documented verification of compliance of the study with GLP principles.
 Inspections to determine the compliance of the study with GLP principles and three types of
inspections are: a) Study based inspections b) Process based inspections c) Facility based
inspections
 Determines any deviation from the approved protocol and report to SD, PI and management.
 Prepare statements to be included in the final report containing dates and types of
inspection.

9. 4. Protocol for conduct of non-clinical testing
Protocol for and conduct of a non-clinical laboratory study 1) Protocol 2) Conduct of
a nonclinical study
Contents of protocol:
 Identification
 Title and statement of purpose
 Identification of test (Or control) items
 Names and address of the sponsor, test facility and test site
 Name of the study director and other personnel
 Proposed dates
 Justification for selection of the test system
 Description of the test system
 Experimental design

10. Conduct of a non-clinical laboratory study:
 Study shall be conducted in accordance with the protocol.
 Information of the specimens should be present on the container to
avoid error in recording and storage of data.
 All the data generated shall be recorded directly, promptly and
legibly by ink.

11. 5. Control on animal house
 Located away from testing laboratories preferably in a separate building.
 Contamination risk is reduced by "barrier” system, as well as by providing “clean" and "diary”
corridors.
 Separate areas for animals of different species and studies.
 Separate areas for diagnosis, treatment and control of laboratory animal diseases.
 Lightening should be proper as light intensity and noise level is sufficient.
 Maintain room temperature, humidity and air changes in animal quarters.
 SOPs - for housing, feeding, handling and care of animals.
 Animals should be free of any disease and if, during the course of study, animals contract a disease
then the diseased animals shall be isolated.
 Diagnosis, authorization of treatment, description and date of treatment shall be documented and
retained.
 Animals of different species shall be housed in separated rooms when necessary.
 The animal cages, racks and accessory equipment shall be cleaned and sanitized at appropriate
interval.

12. 6. General facilities
Testing system facilities
 Suitable size, construction and location.
 Adequate degree of separation of different activities.
 Laboratories should be well ventilated, free of dust, drafts and extreme temperatures.
 Minimum l50sq.feet of floor space and minimum 6 linear feet of usable bench space
should be provide for each analyst.
Archive facilities
Secure storage and retrieval of study plans, raw data. final report and specimens to
prevent untimely deterioration.
Waste disposal
Appropriate collection, storage and disposal facilities and decontamination procedures.

13. 7. Report preparation and documentation
Records and Reports includes: 1) Reporting of nonclinical laboratory results
2) Storage, retrieval
And retention of records and data
•Reporting of nonclinical laboratory study results Final report shall contain:
 Information on sponsor and test facility.
 Experimental starting and completion dates.
 Objectives and procedures stated in protocol (including the changes in
protocol).
 Description of materials and test methods.
 A Quality Assurance Program statement.
 Storage (specimens, reference items, raw data and final report).

14. •Storage, retrieval and retention of records and data:
 Archives should be there for orderly storage and expedient of all raw data,
documentation,
 protocols, specimens and final reports.
 Index of materials retained.
 Master schedule sheet, copies of protocols and records of Quality Assurance
inspections shall be maintained by QAU.
 Wet specimens and samples of test and control articles Shall be retained until
the quality of preparation affords evaluation.
 If any study plan is disposed of before expiry the reason to be justified and
documented.
