How to Choose a Courier for Medical Samples and Lab Work

Medical samples are not ordinary consignments. Blood samples, tissue biopsies, swabs, and other biological specimens have specific handling requirements, regulatory obligations, and time constraints that make choosing the right courier essential — not just for service quality, but for patient safety and regulatory compliance.

If your organisation sends or receives medical samples, here's what to look for when choosing a courier service.

The Essential Criteria

1. Understanding of UN3373 regulations. Biological substances are classified under UN3373 (Category B) for transport purposes. Your courier should understand what this means for packaging, labelling, and handling. If they look blank when you mention UN3373, look elsewhere.

2. Appropriate packaging knowledge. Medical samples need triple packaging — a primary receptacle, secondary packaging with absorbent material, and a rigid outer container. Your courier should be familiar with this system and able to advise on correct packaging.

3. Temperature awareness. Some specimens need to be transported at specific temperatures — ambient, refrigerated, or frozen. Your courier should understand these requirements and have appropriate equipment or procedures to maintain the cold chain where needed.

4. Speed and reliability. Many specimens have viability windows — a blood sample that takes too long to reach the laboratory may give inaccurate results or become unusable entirely. Same-day delivery isn't a luxury for medical samples; it's often a clinical necessity.

5. Chain of custody documentation. Medical samples need a clear, documented chain of custody from collection point to laboratory. Your courier should provide documented handover records and proof of delivery.

Questions to Ask a Potential Medical Courier

When evaluating a courier for medical sample transport, ask these questions:

• Are your drivers trained in handling medical specimens?
• Do you understand UN3373 packaging requirements?
• Can you provide same-day collection and delivery?
• What is your typical response time for collections?
• Do you offer out-of-hours and weekend services?
• What insurance coverage do you provide?
• Can you provide documented chain of custody records?
• Do you use dedicated vehicles (no shared loads)?
• Can you set up regular scheduled runs?

Dedicated vs Shared Services for Medical Samples

We've written about this in detail in our guide to dedicated vs shared courier services for medical deliveries. The summary: for medical samples, dedicated is almost always the better choice. Your specimens travel alone, directly from collection to laboratory, with no stops, no depot sorting, and no risk of cross-contamination with other consignments.

Setting Up a Medical Courier Service

If your healthcare organisation needs regular specimen transport — daily collections from clinics, regular runs between hospitals and laboratories, or on-demand urgent collections — we can design a service that fits your specific requirements.
