Specimen Transport & Chain-of-Custody
BCHPR · 50+ sending and receiving lab sites · 2023 – present
2,328-line specimen transport and chain-of-custody tracking system linking sending and receiving REDCap records with study-ID validation and transport-quality assurance — enables 100% specimen accountability across the CHPR lab network.
Highlights
- Bidirectional matching of Specimen Sending (_st) and Specimen Receiving (_sr) records by study ID and timestamp.
- Multi-format study-ID extraction handling 6+ project ID patterns.
- Wide participant tables (one row per study ID) plus long dimensions tables (one row per transport event).
- Automated alerts for missing specimens (sends without receives) and unexpected extras.
- Transport-timing analysis: screening → specimen collection → processing latency.
- Audit trail linking every specimen to its data-entry events for IRB compliance.
- Satisfies regulatory and IRB specimen-handling requirements across GHIT and TB Reach programmes.
