Lot traceability gives a research team a defensible link between the material in hand and the supporting records used to review it.

What to keep together

• Material name, format and label image
• Lot or batch reference
• Analytical documentation
• Receiving date and condition
• Storage transition and location
• Internal disposition or use record

Where traceability often breaks

Common breaks include renaming a sample without preserving the source lot, separating a certificate from the receiving record, or applying one batch result to a different batch. A simple, consistent naming convention prevents much of this ambiguity.
