Sample Receipt & Chain-of-Custody Check
Lab intake checklist for labeling, storage conditions, custody records, and sample integrity at receipt.
Why it matters
Analytical results are only as reliable as the chain of custody from sampling to storage. Mislabeled containers, broken cold chains, or missing custody signatures invalidate tests and delay releases. Reception staff need a fast, mandatory checklist so non-conforming samples are rejected or quarantined before they enter the workflow.
What to check in the field
Sample receipt and custody verification includes:
- Match external label to internal LIMS or register ID
- Verify sample type, matrix, and requested test panel
- Check container integrity, seals, and leakage
- Confirm temperature on arrival for cold-chain samples
- Record sender, collection date/time, and courier reference
- Complete custody transfer signature or digital handoff
- Assign storage location and retention deadline
- Quarantine and notify client if any criterion fails
Regulation and standards context
Accredited laboratories under ISO/IEC 17025 must control sample handling, identification, and storage. Sector rules (environmental, food, clinical) add specific preservation requirements. Documented intake checks support audits and defend results if legal or commercial disputes arise.
How Check8ge helps
Standardize intake across benches with barcode-friendly steps, photo capture of labels and damage, and timestamps for every handoff. Supervisors review quarantine rates and shorten onboarding for temporary staff with the same digital SOP.
