GLP what is a note to file?

A "note to file" in Good Laboratory Practice (GLP) is a document used to clarify or provide additional information regarding specific aspects of a study or experiment. It serves to ensure transparency and traceability, addressing any deviations or issues that may arise during the study that are not fully documented in the official study report. This note helps maintain compliance with regulatory standards by capturing important details that may affect the interpretation of the study results.
