Specimen Shipping Compliance: Packaging Rules for Canadian Labs
A phlebotomy lab in Moncton learned the hard way that specimen transport is not "just putting tubes in a bag." A courier collected a box of blood samples for a regional reference lab, and during a transfer the outer bag split. The box sat on a sorting table for half an hour while staff assumed it was routine mail. It was not. The lab's transport protocol, the courier's training, and the packaging all came under review — and the review took weeks.
In Canada, transporting diagnostic specimens by road, air, rail, or marine is governed by the federal Transportation of Dangerous Goods (TDG) Regulations. Clinics that ship samples — whether across town or across the country — have obligations under those rules, and the obligations start with packaging, not paperwork.
What the TDG Regulations Cover for Specimens
The TDG Regulations classify dangerous goods and set requirements for their transport: classification, documentation, training, and packaging. Human specimens — blood, urine, tissue, and other diagnostic materials — fall under Class 6.2 (Infectious Substances) when they contain or are reasonably expected to contain infectious agents. The practical effect for clinics: shipments must use tested packaging that contains the specimen through normal transport conditions, including a leak-proof primary container, leak-proof secondary packaging, and an outer packaging with absorbent material.
For most clinical samples, the exempt patient specimen provisions apply when the sample is not suspected of containing a Category A pathogen. Exempt does not mean unregulated — it means the packaging and marking requirements are lighter, but the shipper still must meet basic containment standards and ensure anyone handling the package can recognize it as a clinical specimen.
Packaging: The Rule That Saves the Day
The single most important piece of TDG compliance is packaging that performs. A specimen bag with a documented seal rating — the pressure a sealed bag can hold without leaking — is the first line of defense. CliniEco Medical's 95kPa certified specimen bags are manufactured with a documented seal strength for transport use, with a pouch for the requisition form that keeps paperwork separate from the sample.
Beyond the bag, the three-part system matters: primary container (the tube or cup), secondary packaging (the sealed specimen bag), and outer packaging (the courier box) with absorbent material sufficient for the total liquid volume. Training the staff who package samples — not just the courier — closes the gap between "we have the bags" and "we package correctly."
Documentation and the Shipper's Responsibilities
Even exempt patient specimens need a basic transport document or an alternative that identifies the shipper and the contents. Category A shipments, or specimens suspected of containing high-risk pathogens, require the full TDG shipping document, certification, and training record. The responsibility sits with the shipper — the clinic or lab that hands the package to the carrier — not with the courier alone.
Canadian facilities that ship specimens regularly should have three things on file: a written transport procedure, packaging that meets the applicable standard, and evidence that packaging staff have completed TDG awareness training. Provincial health authorities and accreditation bodies routinely ask for these records during inspections.
Building the Transport Kit That Works
A specimen transport station at the clinic entrance, stocked with 95kPa-certified bags, absorbent pads, and a printed checklist, makes compliance the default instead of the exception. The checklist covers: primary container sealed, specimen bag sealed, requisition in the pouch, absorbent present in the outer packaging, and the transport document attached.
Specimen handling also means protecting the people handling it. The staff who package and label samples should wear nitrile gloves, and facilities that collect blood or tissue add sterile gauze sponges and alcohol prep pads to the collection tray so the full workflow runs from one cart.
FAQ
Do all specimen shipments need a TDG shipping document?
Exempt patient specimens need basic identification of shipper and contents, but shipments containing Category A infectious substances require the full TDG documentation. The classification depends on the specimen and clinical context.
What does "95kPa" mean on a specimen bag?
It is the seal-pressure rating: the bag is documented to hold its seal at 95 kilopascals of internal pressure. That documented strength is what makes the bag acceptable as secondary packaging for transport.
Who is responsible for TDG compliance — the clinic or the courier?
Both have duties, but the shipper (the clinic or lab that hands over the package) bears the packaging and classification responsibilities. Training and documentation must be in place before the courier arrives.
Can a regular zip-lock bag be used for specimen transport?
No. Transport requires leak-proof secondary packaging with a documented seal performance and an outer package with absorbent material. A regular zip-lock bag does not meet the containment expectation under the TDG framework.
