How to manage time records for specimen and blood transport

Short answer

Find the laboratory's acceptance instructions for the specimen type and requested analysis. Record collection, carrier handoff, laboratory arrival, and acceptance, matching temperature data where required. If a time or condition is outside specification, do not automatically reject or use the sample; get a decision from the laboratory lead.

Applicable time and temperature conditions depend on specimen type and requested analysis. Do not apply one transport window to blood, serum, and all other samples; check the laboratory's current acceptance instructions before dispatch.

Match specimen ID, collection time, collection point, carrier handoff, and laboratory receipt time on the label or transport form. If procedure requires temperature monitoring, link logger ID, recording interval, and the relevant file to the same chain.

Compare route planning with laboratory receiving hours and stated analysis conditions. Account for collection order, traffic waits, and laboratory closures; keep estimated duration separate from actual arrival and acceptance records.

If records have gaps, a specimen is delayed, or transport conditions appear exceeded, contact the laboratory quality lead. Suitability for analysis and any recollection decision should follow the specialist procedure.
