2. GLP : GOOD LABORATORY PRACTICES
In the experimental (non-clinical) research area, the phrase good
laboratory practice or GLP specifically refers to a quality system of
management controls for research laboratories and organizations to
ensure the uniformity, consistency, reliability, reproducibility, quality,
and integrity of chemical (including pharmaceuticals) non-clinical safety
tests; from physio-chemical properties through acute to chronic toxicity
tests.
3. LP was first introduced in New Zealand and Denmark in 1972, and later
in the US in 1978 in response to the Industrial Bio Test Labs scandal. It
was followed a few years later by the Organization for Economic Co-
operation and Development (OECD) Principles of GLP in 1992; the
OECD has since helped promulgate GLP to many countries.
“Good Laboratory Practice (GLP) embodies a set of principles that
provides a framework within which laboratory studies are planned,
performed, monitored, recorded, reported and archived”.
4. REASON BEHIND THE CREATION OF GLP
:
In the early 70’s FDA became aware of cases of poor laboratory practice
all over the United States.
FDA decided to do an in-depth investigation on 40 toxicology labs.
They discovered a lot fraudulent activities and a lot of poor lab
practices.
Examples of some of these poor lab practices found were
1. Equipment not been calibrated to standard form , therefore giving
wrong measurements.
2. Incorrect/inaccurate accounts of the actual lab study
3. Inadequate test systems
5. One of the labs that went under such an investigation made headline
news. The name of the Lab was Industrial Bio Test.
This was a big lab that ran tests for big companies such as Procter and
Gamble (P & G).
It was discovered that mice that they had used to test cosmetics such as
lotion and deodorants had developed cancer and died.
Industrial Bio Test lab threw the dead mice and covered results
deeming the products good for human consumption.
Those involved in production, distribution and sales for the lab
eventually served jail time.
6. OBJECTIVES OF GLP
GLP 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.
7. THE OECD
The OECD Council, data generated in the testing of chemicals in one
OECD Member Country, in accordance with OECD Test Guidelines and
the Principles of GLP are accepted in all other OECD Member Countries.
GLP is a quality system concerned with the organizational process and
conditions under which non-clinical health and environmental safety
studies are :
- planned,
- performed,
- monitored,
- recorded,
- archived and
- reported.
8. GLP PRINCIPLES
1. Test Facility Organisation and Personnel.
2. Quality Assurance Programme(QAP).
3. Facilities.
4. Apparatus, Material and Reagents.
5. Test systems.
6. Test and Reference Substances.
7. Standard Operating Procedures(SOP).
8. Performance of The Study.
9. Reporting of Study Results.
10. Storage and Retention of Records and materials.
9. 1. TEST FACILITY ORGANIZATIONAL AND
PERSONNEL
Should have the Knowledge of the GLP principles.
Access to the study plan and appropriate SOP’s.
Comply with the instructions of the SOP’s.
Record raw data.
Study personnel are responsible for the quality of their data.
Exercise health precautions to minimize risk.
Ensure the integrity of the study.
10. 2. QUALITY ASSURANCE PROGRAMME
Access to the updated study plans and SOP’s.
Documented verification of the compliance of study plan to the GLP
principles.
Inspections to determine compliance of the study with GLP principles.
Three types of inspection. – Study-based inspections. – Facility-based
inspections. – Process-based inspections.
Inspection of the final reports for accurate and full description.
Report the inspection results to the management.
Statements.
11. 3. FACILITIES
Suitable size, construction and location.
Adequate degree of separation of the different activities.
Isolation of test systems and individual projects to protect from
biological hazards.
Suitable rooms for the diagnosis, treatment and control of diseases.
Storage rooms.
12. 4. APPARATUS , MATERIALS AND
REAGENTS
Apparatus of appropriate design and adequate capacity.
Documented Inspection, cleaning, maintenance and calibration of
apparatus.
Apparatus and materials not to interfere with the test systems.
Chemicals, reagent and solutions should be labelled to indicate identity,
expiry and specific storage instructions.
13. 5. TEST SYSTEMS
Physical and chemical test systems.
Biological test systems.
Records of source, date of arrival, and arrival conditions of test systems.
Proper identification of test systems in their container or when
removed.
Cleaning and sanitization of containers.
Pest control agents to be documented.
14. 6. TEST AND REFERNCE ITEMS
Receipt, handling, sampling and storage
Characterization.
Known stability of test and reference items.
Stability of the test item in its vehicle (container).
Experiments to determine stability in tank mixers used in the field
studies.
Samples for analytical purposes for each batch.
15. 7. STANDARD OPERATING PROCEDURES
(SOPS)
Written procedures for a laboratories program.
They define how to carry out protocol- specified activities.
Most often written in a chronological listing of action steps.
They are written to explain how the procedures are suppose to work.
Routine inspection, cleaning, maintenance, testing and calibration.
Actions to be taken in response to equipment failure.
Keeping records, reporting, storage, mixing, and retrieval of data.
Definition of raw data.
Analytical methods.
16. 8. PERFORMANCE OF THE STUDY
Prepare the Study plan.
Content of the study plan.
› Identification of the study.
› Records.
› Dates.
› Reference to test methods.
› Information concerning the sponsor and facility.
Conduct of the study.
17. 9. REPORTING OF THE STUDY RESULTS
Information on sponsor and test facility.
Experimental starting and completion dates.
A Quality Assurance Program Statement.
Description of materials and test methods.
Results.
Storage (samples, reference items, raw data, final reports) etc.
18. 10. STORAGE AND RETENTION OF
RECORDS AND MATERIALS
The study plan, raw data, samples.
Inspection data and master schedules.
SOPs.
Maintenance and calibration data.
If any study material is disposed of before expiry the reason to be
justified and documented.
Index of materials retained.
19. WHAT GOOD LABORATORY MUST
CONTAIN ?
Area should be free from smoke, smell, dust etc.
Ensure good ventilation, proper illumination and prefer natural light.
Air conditioned the lab with humidity control.
Enough space for measuring and testing instrument.
Proper arrangement of testing.
Take care of all safety points including proper earthing as well as fire
safety.
Avoid uncleanable spots in floors, walls, ceiling.
Establish proper areas for storage of incoming samples as well as test–
completed samples.
Also provide sample collection place as well as packing and disposal of
tested samples.
20. DO THIS FOR GLP
Keep the things at its location after use.
Store heavy things at bottom & if possible on Trollies.
Give name of location to everything.
Follow “Everything has the place & Everything at its place” principle.
Prepare location list & display it.
Put ladders for things stored on top.
Identify everything with its name/ purpose.
21. BENEFITS OF GOOD LABORATORY
PRACTICES
It will give better image of company as a Quality producer in Global
market.
Provide hot tips on analysis of data as well as measure uncertainty and
perfect record keeping.
Provide guideline for doing testing and measurement in detail.
Provide guidelines and better control for maintenance of instruments,
environment control, preservation of test records etc.
22. CONCLUSION
Gives better image of company as a Quality producer in Global market
Provide hot tips on analysis of data as well as measure uncertainty and
perfect record keeping & guideline for doing testing and measurement
in detail.
Finally GLP Provide guidelines and better control for maintenance of
