Every biobank eventually becomes an archive.
The shift usually doesn’t happen on a calendar. It happens quietly, when the same samples start coming back under retired P*s and closed protocols.
They were stored for today’s research. Then, somewhere between year five and year fifteen, they became the raw material for questions no one had thought of yet.
That changes what infrastructure has to do.
A system built for active collection assumes the researcher, the study, and the context are still available.
An archive assumes none of them are.
Every sample question has to be answerable from the record itself.
Not memory.
Not a hallway filing cabinet.
Not the person who built the study and left in 2018.
The biobanks that make this transition well tend to make three early decisions: they treat the audit trail as the primary record, they preserve field-level context, and they choose infrastructure built to outlast current staff.
At what point does a biobank stop being a collection and become an archive?
