ISO 15189 in Canada: What It Requires of Your Sample Transport and Lab Consumables
ISO 15189 is the standard Canadian medical laboratories are measured against when quality and competence are assessed. It is written around the patient result, and most of the requirements land on processes rather than on equipment: how a sample is collected, how it travels, what it is handled in, and what the laboratory can prove afterwards.
This guide covers what the standard expects from sample transport and from the consumables a laboratory buys, and how those two areas show up in an assessment.
What ISO 15189 covers
The standard addresses the whole examination process in three stages: pre-examination, examination and post-examination. Pre-examination is where most laboratory errors originate, and it is also where transport and packaging sit. An assessment looks for evidence that each stage is planned, controlled and recorded — not that a specific product was purchased.
In practice that means documented procedures, defined acceptance and rejection criteria for samples, records that allow a result to be traced back to the sample, the person and the equipment involved, and verification that the laboratory's own methods and materials perform as expected.
What it requires of sample transport
Transport requirements follow from one question: can the laboratory show that the sample arriving at the bench is the same sample, in the same condition, as the one that left the collection site? Four areas carry that burden.
- A documented procedure. Who collects, how the sample is labelled, what temperature it travels at, how long each leg may take, and what happens if it is late. The procedure names the packaging, and staff are trained against it.
- Traceability of the sample and its handling. Unique identification at collection, label integrity through transport, and a handover record that names who passed the sample to whom and when.
- Conditions during transport. Temperature and time limits defined for each sample type, with monitoring where the standard requires it, and a record when conditions were exceeded.
- Containment. Packaging that prevents leakage and cross-contamination, which is where transport regulations and laboratory quality requirements meet.
Two related standards sit alongside: the WHO guidance on the transport of infectious substances for packaging classification, and the IATA dangerous goods requirements for anything moving by air. In Canada, the Transportation of Dangerous Goods Regulations (SOR/2001-286) govern the ground leg.
What it requires of the consumables you buy
Consumables are covered by the standard's requirements for externally provided products and services, and by the requirement that reagents and materials be verified before use. In an assessment, that translates into a short list of habits.
| Requirement | What the laboratory keeps |
|---|---|
| Supplier evaluation | Approved supplier list with the criteria used to approve each one |
| Verification on receipt | Record that the product arrived as specified, undamaged, within date and in the expected quantity |
| Lot traceability | Lot numbers of specimen containers, environmental surface sampling swabs and reagents linked to the samples they handled |
| Storage control | Storage conditions as the manufacturer specifies, with monitoring where those conditions are critical |
| Nonconforming product | What was done when a batch failed verification: quarantine, return, and the effect on results already reported |
The lot traceability line is the one laboratories under-build. When a result is challenged, the question is which specimen container, which transport bag and which reagent lot were in use on that day — and a laboratory that cannot answer has a finding, regardless of how good its analysers are.
How transport and consumables connect
Packaging is both a regulation and a quality control point. A 95 kPa specimen transport bag is a documented component of Category B transport packaging, and it is also the container that keeps a sample intact between the collection site and the bench. Buying the bag as a commodity and treating transport as a courier task leaves a gap that shows up twice: in a transport audit, and in the rejection rate on samples arriving at the laboratory.
Two habits close it. Define packaging as part of the procedure rather than as a purchasing preference, so the same bag type is used across every collection site. And record packaging lot numbers in the same place as container lots, so a containment question can be answered with a document rather than a memory. The same discipline applies to what sits inside the bag: graduated 90 mL specimen cups and individually wrapped swabs carry lot numbers too, and if your laboratory runs its own autoclave for media, the 5-pack spore test trial is the low-cost way to verify that cycle before it enters the quality record.
Consumables for the collection site and the bench are grouped in the clinic supplies collection if you are standardising packaging across sites.
Records an assessor will ask for
Expect requests for: the transport procedure with its temperature and time limits; training records for collection and transport staff; sample rejection logs with reasons; temperature monitoring records where required; the approved supplier list; receipt verification records; and a worked traceability example, from a reported result back to the sample, the container lot and the transport record. CSA Group publishes the Canadian standards that often sit alongside ISO 15189 in facility and device requirements, and they are worth keeping in the same reference folder as the procedure they support.

Frequently Asked Questions
Is ISO 15189 mandatory for medical laboratories in Canada?
The standard is not federal law, but Canadian medical laboratories are assessed against it through provincial quality programs and accreditation arrangements, and it is the reference standard for laboratory quality and competence. Treat it as the framework your quality system is measured against rather than as an optional certificate.
What does ISO 15189 require for sample transport?
A documented procedure covering collection, labelling, packaging, temperature and time limits, and handover; records that trace the sample through each leg; and defined action when conditions or timelines are exceeded. The standard does not name a product — it requires evidence that the process is controlled.
How long does a laboratory need to keep sample records?
Retention periods are set by the standard's record requirements together with provincial rules and your own quality system, so confirm the period that applies to your laboratory. The practical test is whether you can reconstruct what happened to a sample when a result is questioned months later.
Do lower-cost specimen containers put accreditation at risk?
Cost is not the issue; verification is. Every container still has to be verified on receipt, stored as specified, traceable by lot, and fit for the sample type it holds. A lower-cost container that passes those checks is a legitimate choice, while an expensive one that is never verified is a finding.
Does packaging count as part of the quality system or as shipping paperwork?
Both. Category B packaging is regulated under transport rules, and the same package is the container that protects sample integrity, which is a pre-examination quality requirement. Keeping the two views separate is how laboratories end up with compliant shipping paperwork and a rising rejection rate.
