Wedlich, Richard C.; Libera, Agata E.; Pires, Amanda; Therrien, Matthew T. – Journal of Chemical Education, 2013
The Good Laboratory Practice (GLP) regulations were put into place in 1978. They establish a standard of practice to ensure that results from the nonclinical laboratory study reported to the U.S. Food and Drug Administration (FDA) are valid and that the study report accurately reflects the conduct of the study. While the GLP regulations promulgate…
