Yes. The GLPs were written with the aim of being applicable to a broad variety of studies,
test articles and test systems. Nonetheless, the agency realizes that not all of the GLP
provisions apply to all studies and, indeed, for some special studies certain of the GLP
provisions may compromise proper science. For this reason, laboratories may petition the
agency for exemption for certain studies from some of the GLP provisions. The petition
should contain sufficient facts to justify granting the exemption.
