ANNEX I THE OECD PRINCIPLES OF GOOD LABORATORY PRACTICE (GLP)

SECTION I INTRODUCTION

Preface
Government and industry are concerned about the quality of non-clinical health and environmental safety studies upon which hazard assessments are based. As a consequence, OECD Member States have established criteria for the performance of these studies.
To avoid different schemes of implementation that could impede international trade in chemicals, OECD Member States have pursued international harmonisation of test methods and good laboratory practice. In 1979 and 1980 an international group of experts, established under the special programme on the control of chemicals, developed the ‘OECD principles of good laboratory practice’ (GLP), utilising common managerial and scientific practices and experience from various national and international sources. These principles of GLP were adopted by the OECD Council in 1981, as an Annex to the Council Decision on the mutual acceptance of data in the assessment of chemicals (C(81) 30 (final)).
In 1995 and 1996, a new group of experts was formed to revise and update the principles. The current document is the result of the consensus reached by that group. It cancels and replaces the original principles adopted in 1981.
The purpose of these principles of good laboratory practice is to promote the development of quality test data. Comparable quality of test data forms the basis for the mutual acceptance of data among countries. If individual countries can confidently rely on test data developed in other countries, duplicative testing can be avoided, thereby saving time and resources. The application of these principles should help to avoid the creation of technical barriers to trade, and further improve the protection of human health and the environment.

1. Scope
These principles of good laboratory practice should be applied to the non-clinical safety testing of test items contained in pharmaceutical products, pesticide products, cosmetic products, veterinary drugs as well as food additives, feed additives, and industrial chemicals. These test items are frequently synthetic chemicals, but may be of natural or biological origin and, in some circumstances, may be living organisms. The purpose of testing these test items is to obtain data on their properties and/or their safety with respect to human health and/or the environment.
Non-clinical health and environmental safety studies covered by the principles of good laboratory practice include work conducted in the laboratory, in greenhouses, and in the field.
Unless specifically exempted by national legislation, these principles of good laboratory practice apply to all non-clinical health and environmental safety studies required by regulation for the purpose of registering or licensing pharmaceuticals, pesticides, food and feed additives, cosmetic products, veterinary drug products and similar products, and for the regulation of industrial chemicals.

3. All data generated during the conduct of the study should be recorded directly, promptly, accurately, and legibly by the individual entering the data. These entries should be signed or initialled and dated.
4. Any change in the raw data should be made so as not to obscure the previous entry, should indicate the reason for change and should be dated and signed or initialled by the individual making the change.
5. Data generated as a direct computer input should be identified at the time of data input by the individual(s) responsible for direct data entries. Computerised system design should always provide for the retention of full audit trails to show all changes to the data without obscuring the original data. It should be possible to associate all changes to data with the persons having made those changes, for example, by use of timed and dated (electronic) signatures. Reason for changes should be given.

9. Reporting of study results

9.1. General
1. A final report should be prepared for each study. In the case of short-term studies, a standardised final report accompanied by a study specific extension may be prepared.
2. Reports of principal investigators or scientists involved in the study should be signed and dated by them.
3. The final report should be signed and dated by the study director to indicate acceptance of responsibility for the validity of the data. The extent of compliance with these principles of good laboratory practice should be indicated.
4. Corrections and additions to a final report should be in the form of amendments. Amendments should clearly specify the reason for the corrections or additions and should be signed and dated by the study director.
5. Reformatting of the final report to comply with the submission requirements of a national registration or regulatory authority does not constitute a correction, addition or amendment to the final report.

9.2. Content of the final report
The final report should include, but not be limited to, the following information:
1.

Identification of the study, the test item and reference item
(a) A descriptive title
(b) Identification of the test item by code or name (IUPAC, CAS number, biological parameters, etc.)
(c) Identification of the reference item by name
(d) Characterisation of the test item including purity, stability and homogeneity.
2.

Information concerning the sponsor and the test facility
(a) Name and address of the sponsor
(b) Name and address of any test facilities and test sites involved
(c) Name and address of the study director
(d) Name and address of the principal investigator(s) and the phase(s) of the study delegated, if applicable
(e) Name and address of scientists having contributed reports to the final report.
3.

Dates
Experimental starting and completion dates.
4.

Statement
A quality assurance programme statement listing the types of inspections made and their dates, including the phase(s) inspected, and the dates any inspection results were reported to management and to the study director and principal investigator(s), if applicable. This statement would also serve to confirm that the final report reflects the raw data.
5.

Description of materials and test methods
(a) Description of methods and materials used
(b) Reference to OECD test guideline or other test guideline or method.
6.

Results
(a) A summary of results
(b) All information and data required by the study plan
(c) A presentation of the results, including calculations and determinations of statistical significance
(d) An evaluation and discussion of the results and, where appropriate, conclusions.
7.

Storage
The location(s) where the study plan, samples of test and reference items, specimens, raw data and the final report are to be stored.

10. Storage and retention of records and materials
10.1. The following should be retained in the archives for the period specified by the appropriate authorities:
(a) the study plan, raw data, samples of test and reference items, specimens, and the final report of each study;
(b) records of all inspections performed by the quality assurance programme, as well as master schedules;
(c) records of qualifications, training, experience and job descriptions of personnel;
(d) records and reports of the maintenance and calibration of apparatus;
(e) validation documentation for computerised systems;
(f) the historical file of all standard operating procedures;
(g) environmental monitoring records.
In the absence of a required retention period, the final disposition of any study materials should be documented. When samples of test and reference items and specimens are disposed of before the expiry of the required retention period for any reason, this should be justified and documented. Samples of test and reference items and specimens should be retained only as long as the quality of the preparation permits evaluation.
10.2. Material retained in the archives should be indexed so as to facilitate orderly storage and retrieval.
10.3. Only personnel authorised by management should have access to the archives. Movement of material in and out of the archives should be properly recorded.
10.4. If a test facility or an archive contracting facility goes out of business and has no legal successor, the archive should be transferred to the archives of the sponsor(s) of the study(s).
