Understand 50 healthcare logistics terms covering courier services, specimens, cold chain, compliance and custody, with plain language definitions and practical context.
How to use this glossary
These definitions help healthcare teams, laboratories and procurement staff discuss delivery requirements clearly. They explain common terminology, not a universal operating procedure or a certification checklist. Always connect a term to the actual material, route, applicable rules and receiving facility's instructions.
The 50 numbered entries are grouped by service, laboratory handling, temperature, compliance and quality. For a new shipment, first identify what is moving, who can receive it and which conditions must be maintained.
Service and delivery terms
1. Healthcare logistics
The planning, movement and control of materials that support healthcare, including specimens, medications, equipment and supplies. It includes information, storage conditions and handoffs, not just the vehicle trip.
2. Medical courier
A transport provider that moves healthcare materials under agreed handling, security and delivery procedures. The label alone does not establish qualifications for every specimen, controlled substance or specialized shipment.
3. STAT delivery
An urgent delivery requested to support a time sensitive need. STAT does not define one universal arrival time; the sender and provider must agree on the deadline, receiving arrangements and escalation process.
4. Scheduled route
A planned sequence of pickups and deliveries operating at agreed times or intervals. A route should account for material readiness, laboratory cutoffs and receiving hours, not merely distance.
5. On demand delivery
A delivery arranged when a need arises rather than through a recurring schedule. Availability, pickup time, material acceptance and the expected delivery window still require confirmation.
6. Dedicated fleet
Drivers and vehicles assigned to support a particular customer's delivery operation under an agreed arrangement. Dedicated capacity does not automatically mean every shipment travels alone or that every vehicle has specialized equipment.
7. Last mile delivery
The final transport segment to the intended recipient, such as a hospital pharmacy or laboratory receiving desk. Arrival at a building is not necessarily completion of the authorized handoff.
8. Proof of delivery (POD)
Evidence that a shipment was delivered, often recording time, location and the receiving person. POD does not by itself prove that a specimen is acceptable, a drug is usable or legal process was validly served.
9. Service level agreement (SLA)
A documented agreement defining service expectations, responsibilities and performance measures. Useful terms include pickup windows, receipt requirements, exception reporting and how performance will be measured.
10. Key performance indicator (KPI)
A defined measure used to evaluate performance, such as on time receipt or complete custody records. A meaningful KPI specifies its calculation, data source and exclusions so results remain comparable.
Specimen and laboratory terms
11. Specimen
Material collected for examination or testing, such as blood, urine, tissue or a swab. Its identity, container, preservation and handling must match the requested test and receiving laboratory's instructions.
12. Preanalytical phase
The steps before laboratory analysis, including test ordering, patient preparation, collection, processing, storage and transport. Errors during this phase can affect results even when the analytical instrument works correctly.
13. Accessioning
The laboratory's process of receiving and registering a specimen for testing. It commonly includes matching identifiers and orders and assigning a tracking number. Courier delivery and laboratory accessioning are separate events.
14. Specimen integrity
The condition of a specimen and the associated identification needed for its intended testing. Integrity can be affected by collection errors, leakage, delay, incorrect temperature or missing information.
15. Specimen stability
The period and conditions under which a specimen remains suitable for a particular test. Stability depends on the analyte, container, processing and temperature; there is no universal courier time limit.
16. Analyte
The substance or characteristic being measured in a test, such as glucose or a particular antibody. Different analytes in the same specimen can have different preparation and transport requirements.
17. Aliquot
A portion of a specimen separated into another container for testing, storage or referral. Creating an aliquot is a controlled laboratory or clinical task, not an assumed part of routine courier service.
18. Centrifugation
Spinning a specimen at a specified force and duration to separate components. Whether and when this is required depends on the test. A courier should not improvise processing during transport.
19. Hemolysis
The breakdown of red blood cells, releasing their contents into the surrounding fluid. It may interfere with some test results and can arise from collection, processing or handling problems; transport is not always the cause.
20. Specimen rejection
A laboratory decision not to test a specimen because it fails applicable acceptance criteria. Examples include an identifier mismatch, unsuitable container or exceeded stability limit. The laboratory, not the driver, makes that determination.
Temperature and packaging terms
21. Cold chain
A coordinated system for maintaining required temperature conditions through storage and distribution. It includes qualified packaging, monitoring, procedures and response plans. Cold chain does not mean every item uses the same temperature range.
22. Temperature excursion
An event in which material is exposed outside its specified temperature limits. The magnitude, duration and product requirements inform assessment; an excursion does not automatically mean the shipment must be discarded.
23. Digital data logger (DDL)
An electronic device that records measurements, often temperature, at configured intervals. Its suitability depends on the required range, accuracy, calibration, placement and recording settings.
24. Calibration
Comparison of a measuring device against an appropriate reference to establish its measurement performance. Calibration is not identical to adjustment, and the applicable procedure determines acceptable accuracy and documentation.
25. Temperature mapping
A study of temperature distribution within a defined space or system under specified conditions. It helps identify warmer and colder locations and supports decisions about storage placement and monitoring.
26. Qualified packaging
A packaging system shown through documented testing to meet specified performance requirements under defined conditions. Qualification is only relevant when the actual payload, assembly and transport conditions fit its scope.
27. Packout
The specified arrangement of product, containers, insulation, refrigerants and monitoring devices inside a shipment. Changing the arrangement can change performance even when the same individual components are used.
28. Dry ice
Solid carbon dioxide used as a refrigerant. It changes directly into gas and can create pressure and oxygen displacement hazards. Packaging, ventilation and transport rules must be assessed separately from the specimen requirements.
29. Cryogenic transport
Transport using extremely low temperature conditions for a specific material and process. It requires suitable equipment and procedures; it is not interchangeable with refrigerated delivery or an ordinary frozen parcel.
30. Triple packaging
A packaging concept using a primary receptacle, secondary packaging and outer packaging. Exact construction, absorbent material, marking and performance requirements depend on the classification and transport mode; three arbitrary containers are not enough.
Compliance and safety terms
31. HIPAA
The Health Insurance Portability and Accountability Act and associated rules, including protections for certain health information. Saying a courier is HIPAA compliant is not a substitute for assessing its actual privacy and security practices.
32. Protected health information (PHI)
Individually identifiable health information protected by HIPAA when held or transmitted by covered entities or business associates, subject to the rule's definitions and exclusions. Shipment labels and records can contain PHI.
33. Business associate agreement (BAA)
An agreement defining required responsibilities when a business associate handles PHI for a covered entity. Whether a courier is a business associate depends on its activities; limited conduit services are treated differently.
34. OSHA
The Occupational Safety and Health Administration, the federal agency responsible for workplace safety and health standards. Applicable duties depend on the work and exposure, not simply whether a vehicle carries a medical package.
35. Bloodborne pathogens
Disease causing microorganisms present in human blood that can cause disease in humans. OSHA's Bloodborne Pathogens Standard addresses occupational exposure to blood and other potentially infectious materials through defined controls and procedures.
36. Personal protective equipment (PPE)
Equipment worn to reduce exposure to hazards, such as appropriate gloves or eye protection. The required PPE depends on the assessed task and risk; wearing gloves does not replace packaging or safe work practices.
37. CLIA
The Clinical Laboratory Improvement Amendments and implementing requirements for applicable human laboratory testing. CLIA includes laboratory responsibilities for specimen handling and acceptance; it is not a general medical courier certification.
38. CAP accreditation
Laboratory accreditation through the College of American Pathologists. A laboratory must follow its applicable accreditation requirements. Serving an accredited laboratory does not make its courier CAP accredited.
39. DSCSA
The Drug Supply Chain Security Act, which establishes requirements supporting identification and tracing of certain prescription drugs in the United States. Applicability depends on the product, transaction and entity's role; delivery records alone do not satisfy every duty.
40. UN3373
The UN identification number associated with Biological substances, Category B. It is not a universal label for every medical sample. The shipper must determine classification and follow applicable packaging and marking requirements.
Custody, risk and quality terms
41. Category A infectious substance
An infectious substance transported in a form capable of causing permanent disability or life threatening or fatal disease in otherwise healthy humans or animals when exposure occurs. It requires a different assessment and transport process from Category B.
42. Category B infectious substance
An infectious substance that does not meet the criteria for Category A. Classification must be based on the material and relevant rules; not every patient specimen is automatically Category B.
43. Chain of custody
A documented history of possession and transfers for a shipment or specimen. The required records depend on the testing program or use. Routine delivery scans may not replace formal forensic or regulated testing documentation.
44. Traceability
The ability to follow an item's identity, history, location or movement through records. It can connect product or specimen identifiers to relevant handling events, but does not by itself establish product quality or lawful release.
45. Standard operating procedure (SOP)
An approved written instruction describing how a recurring task is performed. A useful SOP identifies responsibilities, required steps, records and exception handling, and is maintained when the process changes.
46. Corrective and preventive action (CAPA)
A structured process for investigating quality problems, addressing their causes and reducing recurrence or preventing potential problems. A CAPA should include an effectiveness check, not merely a note that staff were reminded.
47. Deviation
A departure from an approved instruction, expected condition or specified requirement. Deviations should be documented and evaluated by the responsible team rather than concealed because delivery was ultimately completed.
48. Quarantine
A controlled hold that prevents material from being used or distributed until an authorized decision is made. Quarantine can involve physical separation and system controls; it is not permission for the courier to decide disposition.
49. Contingency plan
A prepared response to disruptions such as severe weather, vehicle failure or an unavailable receiver. It identifies contacts, alternate arrangements and decision authority while preserving the shipment's required conditions.
50. Reverse logistics
The controlled movement of items back from a recipient, including reusable equipment, packaging or authorized returns. Returned medical products are not automatically suitable for reuse or restocking; the responsible organization must assess them.
Put the terms into practice
Start with the specimen or product instructions, then define the required packaging, pickup window, receiving deadline and evidence of delivery. Assign an escalation contact who can make decisions when conditions change.

Frequently Asked Questions
What is the difference between a medical courier and healthcare logistics?
A medical courier performs transport. Healthcare logistics covers the broader planning and control of materials, information, storage conditions, delivery and handoffs.
Are cold chain and temperature controlled transport the same?
They overlap, but temperature controlled transport can involve different prescribed conditions, not only chilled products. Neither term establishes one universal temperature range.
Does proof of delivery establish chain of custody?
It can support the custody record, but one delivery receipt may not document every required handoff or satisfy a regulated testing program's specific requirements.
Does UN3373 apply to every medical specimen?
No. It is associated with Category B infectious substances. The shipper must determine the material's classification and applicable transport requirements.
