Laboratory sample tracking connects a sample’s identity to the events and locations in its workflow. Start by distinguishing the original sample, each aliquot and its container, then define how receipt, transfer, storage and disposal are recorded and corrected.
Speak directly with Oxford Traceability about laboratory sample identification workflows.
Define when the sample identity is created and how it follows aliquots, containers and storage positions. Map collection, transfer, testing and disposal events, including corrections and relabelling. Trial scanning or RFID capture with the real containers and workflow, and agree who can change records and how those changes are retained.
Trace a sample split without losing the original identity: A laboratory tracking process must distinguish the original sample, its containers and any derived aliquots.
Define which identifier represents the material and which represents its current container. Specify how aliquots relate to their parent sample. Reusing a rack position or replacing a tube must not silently transfer the history of one sample to another.
List receipt, preparation, testing, movement, storage and disposal events that need recording. State when each event becomes complete and who or what confirms it. A scan should have a defined workflow meaning rather than merely adding another timestamp.
Use the real tube, vial, plate or other container with its intended contents and surface condition. Include the storage and cleaning conditions relevant to the laboratory. Check that readable identification remains accessible when samples are placed in racks or storage carriers.
Identify the laboratory or other business system that owns sample identity, status and results. Define the permitted exchange with readers and workflow software. Avoid separate devices independently creating competing records for the same sample.
Specify how staff deal with an unreadable code, unexpected duplicate, incorrect location or interrupted transfer. Require an explicit decision before replacing an identifier. Retain the original event and the reason for a correction where the laboratory’s record policy requires it.
Challenge whether a selected sample can be located and whether a storage position’s contents match the record. Include aliquots and disposed items in the test set. Use the sample tracking integration guide to define interfaces and exception ownership.
Container identification establishes the link at the bench or store. Data integration then preserves that link through transfers, aliquots and exceptions in the laboratory’s record system.
Map original samples, aliquots, containers, locations and the events that change their state.
Trial label or tag reading with the actual containers, racks and storage conditions.
Agree identifiers, event acknowledgement, permissions and handling of unavailable systems.
Test relabelling, duplicate scans, interrupted transfers and retrieval of a complete sample history.
Your final solution for laboratory sample identification workflows must reflect the law, current standards and site-specific risks that apply to your installation.
