Quick facts
- Canada: Public Health Ontario states its acceptance criteria in terms of the packaging, requiring that "the specimen packaging meets the minimum Federal Regulation - Transportation of Dangerous Goods packaging requirements" and that "the specimen is not leaking".
- Canada: the same criteria turn on labelling, and a specimen whose patient identification is missing, incomplete or conflicting may be rejected, with a signed waiver by the submitting health care provider available in some cases.
- United States: 49 CFR 173.199 writes the packaging structure into the text, describing "a triple packaging consisting of a primary receptacle, a secondary packaging, and a rigid outer packaging".
- United States: under the Clinical Laboratory Improvement Amendments, 42 CFR 493.1105 sets retention requirements, including records of test requisitions and authorizations for "at least 2 years".
- United States: 42 CFR 493.1253 places verification duties on a laboratory that introduces an unmodified, cleared test system, which is why an acceptance criterion is tied to a documented method rather than to habit.
- Canadian criteria cited here were retrieved 2026-09-26; the American transport text was retrieved 2026-09-27.
A specimen moves from a collection area to a laboratory bench, and the part of that journey a clinic controls is the packaging and the label. Both countries refuse a specimen that arrives damaged or mislabelled, but they say so in different places: one writes the packaging structure into the transport regulation, and the other makes compliance with that regulation a condition of acceptance. The difference changes what a rejection letter can cite, and it changes what a clinic should record before the courier arrives.
Does Canada reject a specimen for packaging reasons?
Yes, and the packaging test is a reference to a federal instrument rather than a description of the packaging itself.
Public Health Ontario's acceptance criteria state the condition directly: "The specimen packaging meets the minimum Federal Regulation - Transportation of Dangerous Goods packaging requirements". The criterion does not restate the requirement; it points to it. The second condition is stated in the same list and is physical: "The specimen is not leaking."
That structure has a practical consequence. A Canadian clinic cannot verify its own packaging against a local description alone, because the description sits in the federal dangerous goods regulation. The packaging that a courier accepts is the packaging that the regulation defines, and a clinic's own procedure is a restatement of that regulation rather than a substitute for it.
The labelling side is also stated as an acceptance criterion. Patient identification that is missing, incomplete or conflicting can trigger rejection, and where the submitting provider takes responsibility, a signed waiver can accompany the specimen. A clinic that keeps both the packaging record and the identification check on the same line can answer a rejection question with the record rather than with a recollection.
| Acceptance condition | Canada | United States |
|---|---|---|
| Packaging basis | Federal dangerous goods packaging requirements, cited by the receiving laboratory | Triple packaging written into 49 CFR 173.199 |
| Leak condition | The specimen is not leaking | The primary receptacle must not leak under the stated test |
| Identification failure | Missing, incomplete or conflicting identification may be rejected | Rejection is set by the laboratory's own criteria |
| Provider waiver | A signed waiver is available in some cases | Not a feature of the federal transport text |
| Where the condition is stated | The receiving laboratory's acceptance criteria | The transport regulation |
What does the American transport rule require in structure?
Three layers, named, rather than a performance statement.
Section 49 CFR 173.199 describes "a triple packaging consisting of a primary receptacle, a secondary packaging, and a rigid outer packaging". The text then adds the conditions that each layer carries: the primary receptacle holds the specimen, the secondary packaging contains absorbent material, and the rigid outer packaging carries the marking. The structure is written into the rule rather than left to a performance specification.
For a clinic, the structural description is easier to check than a performance statement. A three-layer pack either has three layers or it does not, and the absorbent material is either present in the secondary layer or it is absent. A pack that is described only as leak-proof without the layer structure is being described in language the transport rule does not use.
Canada points to its own danger goods regulation rather than restating the layer structure in the acceptance criteria, so the two jurisdictions reach a similar physical result from different drafting. The clinic's check is the same either way, and the record should name the layers.
| Layer | Role | What to record |
|---|---|---|
| Primary receptacle | Holds the specimen and must not leak | The container type and the closure |
| Secondary packaging | Contains absorbent material | The absorbent present and its position |
| Rigid outer packaging | Protects the pack and carries the marking | The marking and the outer type |
| Documentation | Travels with the specimen | The requisition and its placement outside the inner layers |
How long must an American laboratory keep the requisition?
Two years, and the requirement is written for the record rather than for the specimen.
Section 42 CFR 493.1105 provides that a laboratory "must retain its records and, as applicable, slides, blocks, and tissues". For test requisitions and authorizations the period is "at least 2 years", and for test procedures a copy is kept "for at least 2 years after a procedure has been discontinued", with the dates of initial use and discontinuance recorded.
That requirement sits beside the acceptance question because a rejection is a record event. A specimen that is refused is refused for a reason, and the reason has to survive an inspection. A clinic that keeps a rejection register with the criterion that was not met is keeping the record the retention rule expects the receiving laboratory to hold.
The verification duty completes the picture. Section 42 CFR 493.1253 addresses the performance specifications a laboratory establishes or verifies when it introduces a test system, which is why an acceptance criterion is tied to a documented method rather than to a preference. A criterion that is not tied to a method cannot be verified.
What does a Canadian clinic record for specimen transport?
Six records, and the two that most often go missing are the packaging layers and the time out of refrigeration.
- The packaging layers. Primary, secondary and outer, recorded separately, so a missing absorbent layer is visible in the record.
- The identification check. Confirmed complete and non-conflicting, with the check recorded at collection rather than at handover.
- The time of collection. Part of the transport clock and the first field a receiving laboratory reads.
- The storage before transport. The temperature the specimen was held at, and the duration, since a delay past the stated window changes acceptance.
- The transport conditions. Ambient or refrigerated, and the packaging that was used for each.
- The rejection record. If a specimen is refused, the criterion not met, the date, and the action taken.
A clinic that keeps these six fields can answer a rejection question from its own file and can show the corrective action without reconstructing the day.
Which criteria vary between laboratories?
Five, and the variation is the reason a single national answer is not enough.
- Identification thresholds. What counts as incomplete identification is set by the receiving laboratory, so two laboratories can accept and refuse the same label.
- Stability windows. The time a specimen remains acceptable depends on the analyte, so the window is a property of the test rather than of the packaging.
- Temperature conditions. Ambient, refrigerated or frozen, which the collection instruction states and the acceptance criteria enforce.
- Minimum volume. A volume below the stated minimum is a specimen problem, not a device problem, and it is refused without reference to the container.
- Container type. The specified container is part of the instruction, so an otherwise acceptable specimen in the wrong container can be refused.
A collection procedure that names all five, and records the value against the specimen, is answering the question the receiving laboratory is going to ask.
Which consumables does a collection point restock?
A collection point runs on containers and transport packaging, and the two are ordered together. For clinics and multi-site groups buying at case level, the wholesale ordering page sets out account and case terms, and the B2B wholesale collection lists the lines held for institutional buyers. The 95 kPa specimen transport bags cover the outer layer, the graduated specimen cups cover the primary receptacle, and a site that also runs its own steriliser can pair the monitoring collection with the biological indicator 5-pack trial.

A rejection is a record event, and the record should be as short as the reason. The printable specimen rejection log is a free sheet with a column for the criterion not met and a column for the corrective action, so a refusal is not written as a note. The generator sized to a collection point builds the sheet from the number of specimens a site sends and the tests it collects for, which keeps a family practice from being handed a reference-laboratory form. No account and no sign-up are needed to open either one.
Where a packaging requirement or an acceptance criterion needs to be explained for a courier dispute or an inspection, the written answer is the one worth having. Ask a compliance specialist and a written answer comes back specific to your equipment and province, with the regulation or standard it is based on cited.

Frequently Asked Questions
What packaging does a Canadian laboratory require for a specimen?
Public Health Ontario's acceptance criteria require that the specimen packaging meet the minimum federal Transportation of Dangerous Goods packaging requirements, and that the specimen not be leaking. The criteria cite the federal instrument rather than restating the packaging itself.
What is triple packaging under the American rule?
Section 49 CFR 173.199 describes a triple packaging consisting of a primary receptacle, a secondary packaging and a rigid outer packaging, with absorbent material in the secondary layer and the marking carried on the rigid outer packaging.
Can a specimen be refused for a labelling problem in Canada?
Yes. Identification that is missing, incomplete or conflicting may lead to rejection, and where the submitting health care provider takes responsibility, a signed waiver can accompany the specimen.
How long must an American laboratory keep a test requisition?
Section 42 CFR 493.1105 requires records of test requisitions and authorizations to be retained for at least 2 years, and a copy of each test procedure for at least 2 years after the procedure is discontinued.
Which criteria differ between laboratories?
Identification thresholds, stability windows, temperature conditions, minimum volume and the specified container type. Each is set by the receiving laboratory and by the analyte, so a single national answer does not cover them.
What should a clinic record before a courier collects?
Record the primary, secondary and outer packaging layers, the identification check, the time of collection, the storage temperature and duration, the transport conditions, and any rejection with the criterion that was not met.
