First, confirm acceptance.
Confirm the service, material type, quantity, container or transport medium, required temperature, maximum transit time, delivery address and receiving arrangements with PLS. There is no single transport condition suitable for every sample.
Ask about sample requirements →A specimen listed on an assay page does not confirm that PLS accepts it. Do not send clinical diagnostic samples, cultures or suspected high-risk infectious material without explicit written acceptance and an appropriate shipping plan. This page does not establish PLS diagnostic or high-containment capability.
The basic packaging principle
Three protective layers
- 1
Primary container
A compatible, securely closed, leakproof sample container. For liquids, add enough absorbent material to contain the entire contents if a leak occurs.
- 2
Secondary packaging
Leakproof packaging around the primary container and absorbent material. Separate and cushion individual containers so they cannot strike one another.
- 3
Outer packaging
A sturdy outer package that protects the contents during transport, with the required shipping marks, labels and documentation.
These three layers explain the packaging principle; they are not a complete packing instruction or certification. A trained, competent shipper must determine classification, compliant packaging, markings, documents and any permits under current national, route and carrier rules. Research use does not automatically make a specimen exempt. Dry ice has additional dangerous-goods requirements.
See the WHO transport guide and IATA dangerous-goods requirements.
What to confirm for your material
Storage temperature and transit limits must come from the agreed, sample-specific instructions. CDC shipping guidance likewise directs submitters to test-specific requirements.
- Samples for DNA extraction
- Confirm the source material, container or preservative, quantity and storage history before collection. Follow the project-specific transport instructions supplied after acceptance.
- Extracted DNA or RNA
- For quantification or PCR, agree the buffer, concentration, volume and aliquot format. Protect against contamination and follow the agreed temperature and handling requirements; do not assume all nucleic acids can travel at room temperature.
- PCR products for gels or Sanger sequencing
- Confirm the product identity, expected size, cleanup status, buffer and required aliquots. For sequencing, also agree primer requirements. Use the approved preparation and transport conditions.
- Plasma or nasopharyngeal swabs
- These specimen types appear in the assay portfolio. Confirm acceptance, collection tube or swab medium and assay-specific handling before collection or dispatch; product-kit storage instructions do not apply to specimens.
