What set of principles guides the planning of laboratory studies?

Good laboratory practices (GLP) provide a framework for the planning, execution, and reporting of laboratory studies. These principles are essential for ensuring the quality and integrity of data generated during scientific research, especially in fields related to biomedical and environmental studies. GLP encompasses aspects such as personnel training, equipment calibration, maintenance of laboratory records, and standard operating procedures. By adhering to GLP, laboratories can ensure that studies are conducted consistently and that results are reproducible, which is crucial for regulatory acceptance and scientific validity.

Other frameworks, like ISO standards, FDA regulations, and CLIA regulations, address specific areas of laboratory operations or compliance. However, GLP is specifically focused on the overall management and conduct of laboratory studies, making it the most relevant answer for the planning of such studies.
