Specimen Tracking,
From Collection to Accessioning

Build a searchable chain of custody for Pathology, Histology, and Cytology—with passive RFID that reads through sealed bags/containers, fast recovery, and LIS-aligned events.

Why Specimen Tracking Matters

Every tube, cup, or cassette can determine a care plan—especially in Pathology, Histology, and Cytology, where specimens are irreplaceable once collected. Breaks in custody, off-route bags, or missed arrivals stall diagnosis, raise costs, and elevate legal exposure. A modern program creates a searchable, time-stamped trail from collection to accessioning, with rapid recovery tools and temperature oversight for items requiring refrigeration or freezing.

What Leaders Gain

  • Network-wide visibility across inpatient units, clinics, couriers, and core labs
  • Faster recovery when an item is missing or off route
  • Audit-ready evidence for CAP, Joint Commission, and internal QA
  • Lower exposure tied to lost/mixed Pathology, Histology, Cytology specimens
  • Documented cold-chain compliance for cooled/frozen materials
  • Lower exposure to litigation risk tied to lost or mixed specimens

How An Automated Specimen Tracking System Works (Executive View)

1. Label & link at collection
The barcode remains the clinical label. Add a passive RFID label (or paired ID) carrying a non-PHI key linked to the LIS order (accession). Apply policies for container types used in Pathology/Histology/Cytology—including cassettes, slides, and fluid containers.

2. Automate handoffs
Fixed readers at unit exits, dispatch hubs, pneumatic-tube entry/exit, lab receiving thresholds, refrigerators/freezers, and processing benches generate automatic “departed/arrived” events—no added steps. Overhead ceiling mounts in hallways and elevator lobbies capture motion between departments.

3. Keep the transport leg visible
When a bag or cooler leaves a unit, start an expected-arrival timer per route. Receiving reconciles expected vs. seen immediately, flagging any missing LIS orders.

4. Recover fast when there's a gap
Handheld readers guide staff by signal strength to locate a sealed or misplaced specimen—no line of sight, even inside coolers.

5. Cold chain, where required
For specimens that must be refrigerated or frozen, simple temperature loggers in coolers post a pass/fail result at receipt. Store that alongside custody events for an integrated integrity record.

6. Integrate with LIS
Post concise time/place events keyed to the accession; retain detailed exception notes for QA and audits.

Align Tracking with LIS Milestones

Mirror real lab flow so data is meaningful without noise.
  • Order created
  • Specimen(s) collected & tagged
  • Packed/associated to bag/cooler
  • Depart unit
  • Arrive receiving
  • Accessioned
  • Processing/Storage (ambient/2–8 °C/frozen)

Exceptions:

  • Partial receipt
  • Missed arrival (timer expired)
  • Retag/correction
  • Cold-chain fail/pass
  • Off-route find

Specimen Tracking Without Line of Sight

Barcodes are essential, but depend on manual scans. Passive RFID reads through bags and sealed containers, detects many items at once, and posts movement as items pass through read zones.

That’s how you cut the time to find a misplaced Histology cassette or Cytology slide from minutes to seconds—without opening containers or breaking seals.

Fixed RFID Readers + Handhelds: The “Trail and Find” Model

  • Fixed infrastructure sets the trail: doorway/overhead read zones create a trustworthy last observed location and expected-arrival timing for Pathology/Histology/Cytology items.

  • Handhelds close the loop: a proximity sweep along the courier path, staging racks, refrigerators/freezers, or pneumatic-tube stations quickly locates the item—even in sealed coolers.

  • Simple roles: units associate specimens to a bag/cooler ID; couriers move through portals; receiving reconciles and handles exceptions; the system records the rest.

Controls That Reduce Risk (And Stress)

  • RECONCILIATION AT RECEIPT

    Instant match of expected vs. received; task queue for missing accessions.

    TIMERS ON ROUTES

    Alerts when a bag hasn’t arrived within the target window.

  • COLD-CHAIN EVIDENCE

    Temperature pass/fail recorded with custody for cooled and frozen specimens.

    CORRECTION EVENTS

    Document re-labels, damaged containers, or re-tags for a defensible trail.

PRIVACY BY DESIGN

PHI stays in LIS; tags carry non-PHI keys; access is role-based with audit logs.

Key Performance Indicators

  • Lost or delayed specimens per 10,000 orders (highlight Path/Hist/Cyto)
  • Median time to locate a missing item (target: <5 minutes)
  • Collection-to-receipt turnaround by priority class (STAT/routine)
  • Custody completeness (% orders with a full trail)
  • Receiving auto-match rate (expected vs. seen within 1 minute)
  • Re-collection rate and cost avoidance
  • Cold-chain excursions per 1,000 cooled/frozen shipments

Specimen Chain of Custody Implementation Playbook

(Start Small, Scale Fast)

  1. Pick one high-volume route (e.g., ED/OR/clinic → Core Lab Pathology). Add a receiving portal and handheld checkout at the unit.
  2. Associate to bags/coolers with a quick bench scan or handheld step; start timers at unit exit.
  3. Turn on reconciliation at receiving; triage exceptions the same shift.
  4. Add unit portals on the busiest floors; extend to pneumatic-tube checkpoints.
  5. Standardize label policy by container/temperature range for Pathology/Histology/Cytology; define retention rules and QA cadence.
  6. Scale across hospitals and ambulatory sites with the same blueprint.

Automation Technology Choices for Specimen Tracking—Keep It Pragmatic

Identifiers

Barcode/2D remains the clinical label; add passive RFID for automated custody and fast recovery.

Read Zones

Unit exits, dispatch hubs, pneumatic-tube entry/exit, lab receiving, cold storage (2–8 °C, frozen), and overhead hall mounts.

Handhelds

Essential for recovery, ad-hoc audits, and documenting corrections at the point of work—including finds in refrigerators/freezers.

Mobile Computing

Combine barcode/RFID capture, secure messages, and checklists in one device to minimize steps.

Interfaces

Standard LIS events via the interface engine or approved APIs; buffer/replay during outages; avoid duplicates.

Governance

Role-based access, audit logs, change control, and routine read-rate monitoring to keep the signal trustworthy.

FAQs

No—barcode stays the identifier. Automated custody uses non-PHI keys linked to the accession.
Yes—with the right labels and placement. Validate read performance in refrigerated/frozen conditions during a site survey.
Fixed portals automate most events. Handheld steps focus on checkout and exception recovery, not routine scanning.
An end-to-end, time-stamped custody record—plus cold-chain results and faster recovery—helps prevent errors and strengthens your defense when incidents occur.
