Quick answer
Understand 50 healthcare logistics terms covering courier services, specimens, cold chain, compliance and custody. Use these plain language definitions for your daily operations.
How to use this glossary
These definitions help healthcare teams, laboratories and procurement staff discuss delivery needs. This is a reference guide, not a formal policy or checklist. Always match these terms to your materials, routes, and facility rules.
The 50 entries are grouped by service, laboratory handling, temperature, compliance, and quality. Before a shipment, identify what is moving, who receives it and which conditions must be maintained.
Service and delivery terms
1. Healthcare logistics
Planning and managing the movement of health materials. This includes specimens, medications, and equipment. It covers storage, handoffs, and transport.
2. Medical courier
A transport provider that moves health materials. This label does not guarantee the provider is qualified for every type of specialized shipment.
3. STAT delivery
An urgent, time sensitive delivery. You and the provider must agree on deadlines and arrival plans in advance.
4. Scheduled route
A set pickup and delivery schedule. Routes must account for lab hours and material readiness.
5. On demand delivery
A shipment arranged as needed rather than on a set schedule. Always confirm pickup times and delivery windows.
6. Dedicated fleet
Vehicles and drivers assigned to one customer. This does not mean the vehicle is always empty or has special equipment.
7. Last mile delivery
The final trip to the drop off desk or pharmacy. Reaching the building does not mean the handoff is complete.
8. Proof of delivery (POD)
A record showing who received a shipment and when. It does not prove the contents are valid or undamaged.
9. Service level agreement (SLA)
A contract defining service expectations. It should cover delivery windows, receipt rules, and performance tracking.
10. Key performance indicator (KPI)
A metric used to measure performance. Examples include on time arrival or custody records. Always define your data sources clearly.
Specimen and laboratory terms
11. Specimen
Material collected for testing, such as blood, urine, tissue, or a swab. Handling and containers must match the laboratory instructions for the specific test.
12. Preanalytical phase
The steps before testing begins. This includes collection, labeling, and transport. Errors here can ruin test results.
13. Accessioning
The lab process of registering a sample for testing. This involves checking labels and assigning tracking numbers.
14. Specimen integrity
The condition of a sample. It can be ruined by delays, heat, or poor handling during transport.
15. Specimen stability
How long a sample lasts under specific conditions. There is no standard time limit for all shipments.
16. Analyte
The substance being tested, such as glucose. Each analyte may have unique storage or transport needs.
17. Aliquot
A small portion of a sample removed for testing. This is a lab task, not a routine courier service.
18. Centrifugation
Spinning a sample to separate parts. Couriers should not perform this task during transport.
19. Hemolysis
The breakdown of red blood cells. It can interfere with tests and is often caused by poor sample handling.
20. Specimen rejection
When a lab refuses a sample due to issues like leakage or poor labeling. The laboratory decides if a sample is acceptable.
Temperature and packaging terms
21. Cold chain
A system to keep items at the right temperature. This involves specialized packing, monitoring, and planning.
22. Temperature excursion
When a product gets too hot or too cold. This does not always mean the shipment must be thrown away.
23. Digital data logger (DDL)
A tool that tracks temperature. Ensure the device is calibrated and placed correctly.
24. Calibration
Checking a tool against a standard to ensure accuracy. This is not the same as adjusting the tool.
25. Temperature mapping
Testing temperature consistency in a storage area. This helps you choose the best spot for sensitive items.
26. Qualified packaging
Containers proven through testing to hold specific conditions. The packaging must fit the actual shipment conditions.
27. Packout
The exact arrangement of ice packs and insulation. Changing the layout can ruin the protective performance.
28. Dry ice
Frozen carbon dioxide. It requires specific ventilation and safety steps during transport.
29. Cryogenic transport
Shipping at extremely low temperatures. This requires specialized gear, not just standard freezer shipping.
30. Triple packaging
Using three layers for containment. This is a safety standard for hazardous or sensitive samples.
Compliance and safety terms
31. HIPAA
Laws protecting patient health data. Being a courier does not automatically make a firm HIPAA compliant.
32. Protected health information (PHI)
Personal health data covered by HIPAA. Shipping labels and paperwork often contain this sensitive information.
33. Business associate agreement (BAA)
A contract required when handling PHI for a health organization. Not all couriers need a BAA.
34. OSHA
Federal workplace safety agency. Rules apply based on the risks associated with the job tasks.
35. Bloodborne pathogens
Germs found in blood that can cause disease. OSHA rules help prevent worker exposure to these risks.
36. Personal protective equipment (PPE)
Safety gear like gloves or eyewear. It is used to lower the risk of exposure to hazards.
37. CLIA
Laws for lab testing. CLIA rules dictate how labs must receive and handle samples.
38. CAP accreditation
A quality standard for laboratories. Serving an accredited lab does not make the courier accredited.
39. DSCSA
A law for tracing prescription drugs. Records are needed to meet these government tracking requirements.
40. UN3373
The label for biological substances, Category B. It is not for every medical shipment.
Custody, risk and quality terms
41. Category A infectious substance
Material capable of causing severe disease. It requires strict transport and safety protocols.
42. Category B infectious substance
Biological material that does not meet Category A criteria. Classify materials correctly before shipping.
43. Chain of custody
A record of who handled a package. Use formal records when strict legal proof or regulated forensic testing is needed.
44. Traceability
Tracking the history of an item. It records the movement but does not guarantee product quality.
45. Standard operating procedure (SOP)
A written guide for recurring tasks. Update your SOPs whenever your processes change.
46. Corrective and preventive action (CAPA)
A plan to fix quality problems and prevent them from happening again.
47. Deviation
A departure from standard rules. Always document deviations rather than hiding them.
48. Quarantine
Holding items to prevent use until they are cleared. This is a formal safety hold.
49. Contingency plan
A backup plan for emergencies like bad weather. Identify who makes decisions when things go wrong.
50. Reverse logistics
Moving items back from the user, like returns. Returned goods must be checked before reuse.
Put the terms into practice
Start with product instructions to define your packaging and delivery deadlines. Identify a contact who can make decisions during transit.

Key Takeaways
- A service label does not establish capability for every medical shipment.
- Handling requirements depend on the material, test, transport mode and receiving process.
- Delivery evidence supports, but does not replace, clinical or quality acceptance.
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.
