GLP is a quality system of management controls for research laboratories and organizations to ensure the uniformity, consistency, reliability, reproducibility, quality, and integrity of products in development for human or animal health (including pharmaceuticals) through non-clinical safety tests; from physio-chemical properties through acute to chronic toxicity tests.
GLP applies to non-clinical studies conducted for the assessment of the safety or efficacy of products in development (including pharmaceuticals) for people, animals, and the environment. GLP, a data and operational quality system, is not the same as standards for laboratory safety – appropriate gloves, glasses and clothing to handle lab materials safely. The principles of GLP aim to ensure and promote safety, consistency, high quality, and reliability of chemicals in the process of non-clinical and laboratory testing. GLP is not limited to chemicals and also applies to medical devices, food additives, food packaging, colour additives, animal food additives, other non-pharmaceutical products or ingredients, biological products, and electronic products.
A laboratory is a facility that provides controlled conditions in which scientific or technological research, experiments, and measurement may be performed. Laboratory services are provided in a variety of settings: physicians’ offices, clinics, hospitals, and regional and national referral centers.
Reliability describes the ability of a system or component to function under stated conditions for a specified period of time. Reliability is closely related to availability, which is typically described as the ability of a component or system to function at a specified moment or interval of time.
Reproducibility is a major principle underpinning the scientific method. For the findings of a study to be reproducible means that results obtained by an experiment or an observational study or in a statistical analysis of a data set should be achieved again with a high degree of reliability when the study is replicated.. There are different kinds of replication but typically replication studies involve different researchers using the same methodology. Only after one or several such successful replications should a result be recognized as scientific knowledge.
