Interpret exposure records against evidence for the same material and packaging.
Exposure is not the same as a stability conclusion
ICH Q1A(R2) addresses changes over time under environmental influences such as temperature, humidity and light, with relevant packaging. A transport log records exposure. Its effect on quality requires corresponding stability and analytical evidence.

Packaging and material state also matter
Q5C discusses interactions with container-closure systems and distinguishes the stability of freeze-dried material from stability after reconstitution. A review should identify the tested material state and packaging combination before applying its conclusions elsewhere.

Organize the evidence as a complete timeline
Organize storage, transfer and receipt records chronologically and connect them to sample identifiers, packaging and test results. These are general ideas for reading quality evidence. The cited guidelines have specific scopes and do not establish storage conditions or a shelf life for an individual research sample.
