What Is Good Laboratory Practice

many of these concerns relevant to the FBI lab are not apphcable to many other laboratories. But they illustrate the importance of instituting good laboratory practices. Had the FBI lab been more diligent in the care of its practices, it may have avoided the turmoil of this investigation. 

The exact definition of good laboratory practice depends on who is defining it and for what purpose. A broad definition encompasses such issues as organization of the laboratory, management, personnel, facilities, equipment, operations, method validation, quality assurance, and record keeping. The goal is to certify that every 

GOOD LABORATORY PRACTICE QUALITY ASSURANCE OF ANALYTICAL MEASUREMENTS 

The laboratory should have SOPs for every method. 

The QAU is responsible for assuring good laboratoiy practices are implemented. Everyone in the lab is responsible for following them.

This chapter introduces the most important aspect of TEQA for the reader After the basics of what constitutes good laboratory practice are discussed, the concept of instrumental calibration is introduced and the mathematics used to establish such calibrations are developed. The uncertainty present in the interpolation of the calibration is then introduced. A comparison is made between the more conventional approach to determining instrument detection limits and the more contemporary approaches that have recently been discussed in the literature (1-6). These more contemporary approaches use least squares regression and incorporate relevant elements from statistics (7). Quality assurance/quality control principles are then introduced. The chapter ends with a comparison of the performance from two hypothetical labs. Every employer wants to hire an analyst who knows of and practices good laboratory behavior. 

Chemists whose work is characterized by good laboratory practice will work in such a way that they make sure they fully understand what it is they have to do before they begin work. They will always be in control of their actions. 

Much of what is done (and how it is done) in repeat-dose studies is a response to a number of regulations. Three of these have very broad impact. These are the Good Laboratory Practices requirements, Animal Welfare Act requirements, and regulatory requirements that actually govern study design. 

Data are evaluated by considering their relevance to the measurement and assessment endpoints selected during problem formulation. The analysis techniques that will be used also are considered data that minimize the need for extrapolation are desirable. Data quality (e.g., sufficiency of replications, adherence to good laboratory practices) is another important consideration. Finally, characteristics of the ecosystem potentially at risk will influence what data will be used. Ideally, the test system reflects the physical attributes of the ecosystem and will include the ecological components and life stages examined in the risk assessment. 

In order to be able to recognise what Good Laboratory Practice is all about, what this set of rules intends to achieve, and in what advantages the application of these principles should result, it might be useful to look at the interpretations of this term from different angles. The term Good Laboratory Practice may invoke three different notions, two of which are inaccurate if not even completely false ... 

The definition of a non-clinical health and environmental safety study takes up again the scope of Good Laboratory Practice in reiterating that it means an experiment or set of experiments in which a test item is examined under laboratory conditions or in the environment to obtain data on its properties and/or its safety, intended for submission to appropriate regulatory authorities . While it should be clear in general, what a study is, there may be some need for additional clarifications regarding what may constitute a study under GLP . 

What is a Validation Master Plan There is no official definition however, based on the interpretation of FDA regulatory guidelines on current Good Manufacturing Practice (cGMP), Good Laboratory Practice, and process validation, a suitable definition may be described as ... 

The major regulatory guidelines for Good Manufacturing Practice (GMP) and Good Laboratory Practice (GLP) are similarly vague. Fitness for purpose is the phrase that is commonly used, but what does this mean in practice ...
