The document outlines Good Laboratory Practices (GLP), which are essential for ensuring the quality and validity of test data in non-clinical health and environmental studies. It details the objectives, principles, and responsibilities associated with GLP, including the organization of test facilities, personnel qualifications, and adherence to standard operating procedures. Additionally, it emphasizes the importance of accurate record keeping, quality assurance, and the retention of study materials to ensure compliance and integrity in laboratory practices.

3. Good laboratory practices -
“A quality system related with the organizational process and the conditions under which non-
clinical health and environmental safety studies are planned, performed, monitored, recorded,
archived and reported.”
GLP describes good practices for non-clinical lab studies that support research or marketing
approvals for FDA-regulated products.
Purpose of Good laboratory practices –
The principles of good laboratory practice (GLP) is to support the development of quality and
validity of test data used for determining the safety of chemicals and chemical product.

4. Objectives of Good laboratory practices –
• Development of quality test data
• Improve the protection of human health and environment
• Avoid technical barrier
• Comparable quality of test data to avoid duplicative testing

5. • Principles of Good laboratory practice -
 Test facility organization and personnel
 Quality assurance program
 Meeting the requirements of the test facility
 Appratus,material and reagents
 Test system
 Test and reference items
 Standard operating procedures.
 Performance of the study.
 Reporting of study results
 Storage and retention of records and materials.

6. 1. Test facility organization and personnel –
a) Test facility management’s responsibility –
• Well educated or qualified personnel.
• Appropriate facilities,equipments and materials are available.
• Test facility should be of appropriate size,costruction and location to meet requirement of
study.
• Ensure that personnel clearly understand the function that they are to perform.
• Valid standard operating procedures are established.
• Ensure maintenance of records of the qualification, training and experience of individual.
• Ensure that study director has made the approved study plan.

7. b) Principal investigator’s responsibilities –
• Investigator will ensure that study conducted in accordance with applicable principles
of GLP.
• Approve the study plan and any amendments and SOP’s are available to study
personnel.
c) Study directors responsibility –
• Study director has overall responsibility for technical conduct of study and fir
interpretation,analysis,documentation and reporting of results.
• Study director has responsibility of for overall quality and integrity of study.

8. d) Study personnel responsibilities –
• Personnel involved in the study must be knowledgeable in those parts of principles of
GLP.
• Access to the study plan and appropriate SOP’s
• Record raw data.
• Study personnel are responsible for quality of their data.
• Exercise health precautions to minimize risk.
• Ensure the integrity of the study.

9. 2. Quality assurance program –
• Responsibilities of QA personnel –
• Access to the updated study plans and SOP’s
• Documented verification of compliance of study plan to GLP principles.
• Inspection to determine compliance of the study with GLP principles.
3 types of inspection
a) Study based inspection
b) Facility based inspection
c) Process based inspection
• Inspection of final reports for accurate and full description.
• Report the inspection result to management.

10. 3.Facilities –
• Should have sufficient no.of rooms or areas
• Suitable rooms should be available for diagnosis,tratment and control of diseases
• There should be storage rooms or areas as needed for supplies and equipment
• Separate areas for receipts and storage of test and reference items
• Should ensure safe storage for Hazardous substance
• Handling and disposal of wastes should be carried out in such a way as not to jeopardies
the integrity of studies

11. 4. Appratus,material and reagent –
• Validated computerized system used for the generation, storage and retrieval of data and for
controlling environmental factors (Humidity , Temperature)
• Apparatus used in a study should be periodically inspected,cleaned,maintained, calibrated
according to SOP’s
• Apparatus and materials used in a study should not interfere adversely with test systems.
• Chemicals, reagents and solution should be labelled to indicate identity, expiry date and
storage instruction.

12. 5. Test system –
a) Physical / Chemicals –
• Apparatus used for generation of physical or chemical data should be suitable
located and of appropriate design and adequate capacity.
• The integrity of Physical or chemical test system should be ensured.
b) Biological –
• Proper conditions for storage,housing,handling and care of biological test sample.
• Isolation of newly received animal and plant test system until health status is
evaluated.
• Records of source, date of arrival and arrival condition of test system should be
maintained.
• During use, housing or containers for test system should be cleaned and sanitized at
appropriate interval.

13. 6. Test and reference items –
a) Receipt,handling,sampling and storage –
• Records for date of receipt, expiry date, quantities received and used in studies.
• Handling, sampling and storage procedures to ensure homogeneity and stability and avoid
contamination or mix-up.
• Identification information on storage container (expiry date, some storage instruction)
*Characterization –
• Each test and reference item should be appropriately identified .
(e.g.- CAS no.,Code,name,biological parameter)
• Each batch of test or reference items should have identity, batch
no.,purity,composition,concentration.
• Stability of test and reference items under storage and test condition should be known for all
studies.

15. 7.Standard operating procedure –
SOP’s should be available for following categories
a) Test and reference items –
• Receipt,identification,labelling,handling,sampling and storage
b) Appratus,materials and reagents –
• Apparatus – Use,maintainance,cleaning and calibration
• Computerized system – Validation,operation,maintainance,security,change control and back-
up
