    Good Laboratory Practice (GLP) is a quality system concerned with the organisational process and the conditions under which non-clinical health and environmental safety studies are planned, performed, monitored, recorded, archived and reported.

    (OECD, 1997)What is GLP?Adamo JE et al. A roadmap for academic health centers to establish good laboratory practice-compliant infrastructure. Acad Med. 2012 Mar;87(3):27984.


    Historical Background


    GLP TIMELINEGLP was first introduced in New ZealandEarly 1970sIndustrial Bio Test Lab case was most notableFDA became aware of cases of poor laboratory practice all over the US decided to do an in-depth Investigation on 40 toxicology labs.

    197821 CFR, Part 58FDA promulgated the Good Laboratory Practice (GLP) Regulations


    National GLP-compliance Monitoring Authoritywas established by the Department of Science & Technology1981An organization named OECD produced GLP principles that are international standardInternational Standard20022011India becomes full-member for Mutual Acceptance of Data (MAD) in the OECD's Working Group on GLP


    Objectives of GLPTrue reflectionEnsure HonestyInternational acceptanceGLP makes sure that the data submitted are a true reflection of the results that are obtained during the study.GLP also makes sure that not to indulge in any fraud activity by labsPromotes international acceptance of tests


    Scope of GLP (OECD)Principles of GLP apply to all non-clinical health and environmental safety studies required by regulations for the purpose of registering or licensing -

    Pharmaceuticals Pesticides Food and feed additives Cosmetic productsVeterinary drug products and similar productsIndustrial chemicals

    Approval of protocols & the study plan including amendments Ensure QA personnel and study personnel are updated with study plans & SOP Ensure the follow up of SOPs periodically and take appropriate corrective action Archiving Raw data, supporting materials and final report.

    The individual responsible for the overall conduct of the non-clinical health and environmental safety study


    Organisation & Personnel

    Ensures the study is conducted in accordance with GLP

    Recording of all raw data in compliance with the principles of GLP

    Deviations from the instructions to be reported the PI or SD

    Takes health precautions and personal safety

    Apparatus, Materials & ReagentsApparatus, including validated computerised systems should be of appropriate design & adequate capacityChemicals, reagents and solutions should be labelled to indicate identity, Conc, DOE & storage instructionsApparatus to be periodically inspected, cleaned, maintained, and calibrated according to Standard Operating Procedures.Should not interfere adversely with the test systems.


    Test Systems

    Physical/ Chemical appropriately designed apparatus Integrity of test systems to be ensured Biological Proper storage, housing and handling conditionsIsolation of newly received animals / plants for evaluation and acclimatisationInformation regarding identity at the containersRecords of source, date of arrival and arrival conditionInterference & Contamination free test system


    Test & Reference ItemsRecords including item receipt, expiry, quantities and used in studies. Handling, sampling & storage procedures should be identified.

    Verification system for sponsor supplied test item.

    Stability of test & Reference item under storage and test conditions.

    Stability in case of vehicle to be determined.


    Standard Operating Procedure1. Test facility should have a written SOP approved by management

    2. SOPs should be available wherever applicable e.g. Test and reference itemsApparatus, materials and reagentsRecord keeping, reporting, storage and retrievalTest system Quality assurance procedures

    3. Any deviations from SOP should be documented & acknowledged by SD and PI

    GLP in our country


    NGCMA National GLP-compliance Monitoring Authoritywas established by the Department of Science & Technology Approval of the Union Cabinet on April 24, 2002 Full-member for Mutual Acceptance of Data (MAD) in the OECD's Working Group on GLP from March, 2011 The Authority has certified 31 TF in India as GLP compliant


    Scope of GLP application to NGCMA (India)Physical-chemical testingToxicity studiesMutagenicity studiesEnvironmental toxicity studies on aquatic and terrestrial organismsStudies on behaviour in water, soil and air, bio-accumulationStudies on effects on natural ecosystemsAnalytical and chemical testing


    GLP Certification process


    GLP Application form & certificate


    Are we ready for GLP?when we do what we writewhen we write what we doWe will achieve GLP


    GLP is an FDA regulation which is accepted and approved as international standards by OECD

    GLP compliance is monitored in India by NGCMA since 2002. Summary

  • Thank You

    Not GLP Excellence of a laboratoryQuality of an organisationQuality of a productProfessional competence

    PLANNED..which is why great emphasis is placed on the study plan (protocol) and to planned changes throughout the study.PERFORMED.this refers to the standard operat-ing procedures (SOPs) which are a GLP require-ment.RECORDEDi.e. the collection of raw data and the recording of deviations, if any, during the of the problems pre-GLP was that study reports did not always reect the study data accurately. Assuring accuracy in the report has now become an essential part of studies may be audited many years after their completion, it is important that the study data, specimens, samples and reports are properly archived. MONITORED..monitoring by study staff, quality assurance personnel and national inspectors helps to assure GLP compliance.

    *Poorly-trained Study Directors and study personnelPoorly-designed protocolsRaw data badly collected - not correctly identified, without traceability - not verified or approved by responsible personsPoor animal husbandryEquipment not properly calibrated or otherwise qualifiedInadequate archives and retrieval processes

    In 1976, the FDA published a draft regulation on GLP and requested comments from interested parties.After the consultation period, the nal regulation was published in 1978 - This came into force in 1979.
