Good Laboratory Practice: GLP Essentials

Good Laboratory Practice: GLP Essentials: Good Laboratory Practice is a quality system concerned with the organisation and conditions under which applicable non-clinical health and environmental safety studies are planned, performed, monitored, recorded, reported and archived.

Why professionals need this knowledge: GLP study compliance is not synonymous with routine diagnostic laboratory accreditation, and its applicability depends on the type of regulated study.

Step 1: Clarify the study's regulatory purpose, whether GLP applies and which personnel carry specific responsibilities.

Step 2: Establish study plans, equipment and facility controls, SOPs, quality assurance oversight and contemporaneous raw data.

Step 3: Ensure deviations, final reports, specimen retention and archives support transparent reconstruction of the study.

Worked example: A laboratory conducting a regulated non-clinical toxicity study needs traceable study conduct and an independent quality assurance function appropriate to the governing GLP framework.

What to avoid: Assuming every scientific experiment is legally required to be GLP, confusing GLP with GCP or failing to protect archived raw data. An apparently neat form is not a substitute for reliable actions and sound judgement in the real workflow.

Records and audit trail: Study plan, QA inspections, equipment logs, raw data, deviations, final report and archiving records. Accurate records enable independent review and appropriate follow-up when concerns arise.

Try this exercise: Map one study's original data and critical approvals from protocol authorisation to archive retrieval. Discuss the exercise with an appropriately qualified colleague before applying it to a live case.

Standards and references: OECD Principles of Good Laboratory Practice and applicable receiving-country regulation. This is educational material; the approved protocol, governing standard and local law take precedence.
