Cross-References
Important
This section is a fundamental building block of any SOP
The ‘Cross-References’ section of an SOP should list other controlled documents that support or relate to the procedure. Cross-references ensure that users can easily identify associated SOPs, validation documents, and equipment instructions necessary for performing the procedure correctly.
Depending on the procedure, cross-references may include:
Associated SOPs: Related procedures that describe upstream or downstream processes, such as wet-lab procedures or reporting workflows.
Validation and verification documents: References to documents establishing the analytical performance, accuracy, and reproducibility of the pipeline or procedure.
Equipment or instrument SOPs: Instructions for using specific laboratory instruments or software platforms required for the procedure.
Guidelines and standards: Relevant internal or external guidelines, such as laboratory standards, regulatory requirements, or best practice documents.
Attention
If the organisation does not have an electronic document management system (eQMS), cross-references should include version numbers and revision dates to ensure users access the correct version.
