Which statement best applies to Good Laboratory Practices regulations?

• A. They apply to studies of the effect of inorganic compounds on animal subjects.
• B. They apply to non-clinical studies for the assessment of the safety of chemicals to humans, animals, and the environment.
• C. They apply to studies that are done on nonhuman primates that have the potential to cause pain and distress.
• D. They must be applied only under supervised conditions in registered institutions.

Answer: (B)

Good Laboratory Practices establish a quality system for nonclinical safety studies, ensuring that how a study is planned, performed, recorded, and reported is standardized and auditable. This framework is designed to ensure the data from safety tests are reliable and acceptable to regulators. The statement that best fits is that GLP applies to non-clinical studies used to assess the safety of chemicals for humans, animals, and the environment. It covers a wide range of studies, across different substances and organisms, and emphasizes proper protocols, documentation, data integrity, and quality assurance. It’s not limited to a specific type of chemical, a single species, or to studies conducted only in “registered” facilities; rather, it governs how nonclinical safety work is conducted across appropriate settings to support regulatory decisions.
