Quick facts
- United States: a specimen collecting chamber used to preserve the viability or integrity of microorganisms reaches the device rules through 21 CFR 866.2900, which classifies the device as Class I.
- United States: 21 CFR 866.2900 states that the device "may be labeled or otherwise represented as sterile", and that a device used solely to collect concentrated parasites is exempt from premarket notification.
- Canada: a specimen container is an in vitro diagnostic device and takes the rules in Part 2 of Schedule 1 to the Medical Devices Regulations, SOR/98-282, with no entry naming a sputum container.
- Canada: the transport step is governed separately by the federal Transportation of Dangerous Goods Regulations, SOR/2001-286, so the container and its packaging sit under two different instruments.
- Both countries: a sputum specimen for tuberculosis testing is a category B infectious substance, and the packaging that carries it is regulated apart from the container that holds it.
- Canada: regulation text cited here is current to 2026-10-03; the American entry was last amended 84 FR 71800, December 30, 2019.
A sputum container looks like the simplest thing on a respiratory bench. It holds a specimen that has been coughed up, it goes to a laboratory, and the laboratory reports a result. The container itself is a low-risk device, and the part of the chain that carries most of the regulation is not the container at all but the packaging that moves it — which is why the container and the transport bag are two different orders, fetched from two different rules.
What kind of device is a sputum container?
It is a specimen collecting chamber, and the American definition says so in a way that covers the whole chain.
21 CFR 866.2900 describes a microbiological specimen collection and transport device as "a specimen collecting chamber intended for medical purposes to preserve the viability or integrity of microorganisms in specimens during storage of specimens after their collection and during their transport from the collecting area to the laboratory". That sentence covers two job sites. The container has to work while the specimen is still in the room and while it is moving, which is why a screw-cap and a leak-tight seal are part of the device rather than a convenience.
The entry then classifies the device as Class I and, for a container used solely to collect concentrated parasites, exempts it from premarket notification subject to the limits in § 866.9. A sputum container is reached by the same definition because the definition is written around the handling of a specimen, not around a specific specimen type.
| Item | American entry | Class | Note |
|---|---|---|---|
| Specimen collecting chamber | 21 CFR 866.2900 | Class I | Covers storage and transport |
| Sterile collection container | 21 CFR 866.2900 | Class I | May be represented as sterile |
| Concentrated parasite collector | 21 CFR 866.2900 | Class I | Premarket notification exempted |
| Sputum culture medium pairing | 21 CFR 866.2540 | Class I | Reached separately for the medium |
What separates the container from the transport packaging in Canada?
Two instruments, and a buyer who treats them as one tends to under-order the second.
In Canada the container is a device. It is used in the examination of a specimen taken from the body, so it sits in the in vitro diagnostic family and takes the rules in Part 2 of Schedule 1 to the Medical Devices Regulations, SOR/98-282. No entry names a sputum container, so the class is reached by applying the rules to the intended use, and a container that is a primary receptacle for a diagnostic specimen follows the intended-use route.
The transport step is a different instrument. A specimen that is being moved is a dangerous good when it contains a pathogen, and the packaging that carries it is governed by the federal Transportation of Dangerous Goods Regulations, SOR/2001-286. A sputum specimen for tuberculosis testing is a category B infectious substance, and the packaging for a category B substance has its own requirements for the primary receptacle, the secondary packaging and the outer packaging.
That is the split a laboratory sees in its own supply list. The container is ordered as a device and the transport bag is ordered as packaging, and the Public Health Ontario specimen acceptance criteria are where an Ontario laboratory checks that both have been met before a specimen is accepted.
| Item | Canada | United States |
|---|---|---|
| Route for the container | Part 2 rules, intended use | 21 CFR 866.2900 |
| Class of the container | Reached from the rules | Class I |
| Sterile representation | Per the device record | Permitted by the entry |
| Transport packaging | Transportation of Dangerous Goods Regulations | Category B packaging rules |
| Where acceptance is stated | The laboratory's acceptance criteria | The laboratory's acceptance criteria |
Why does a sputum specimen need a deep-cough specimen?
Because a specimen that is mostly saliva does not carry the organism the test is looking for, and the collection instruction decides the quality of everything downstream.
A sputum specimen for a respiratory infection is expected to come from the lower airway, which is why the instruction given to the patient is part of the test rather than an afterthought. Public Health Ontario carries the collection details that a laboratory expects to see met, and the World Health Organization sets out the role of tuberculosis testing in its programme guidance. A container that is handed over with a collection instruction and a transport bag beside it is doing three jobs at once, and only one of them is the container.
The standard that sits beside the culture step is ISO 11133:2014, which covers the preparation of culture media, and the standard that sits over the laboratory as a whole is ISO 15189:2022.
A container that is handled correctly and a specimen that is collected poorly still produce a rejected specimen, so the collection step and the transport step are written as one chain rather than two. The instruction handed to the patient is the part of that chain that no container can carry on its own, and a bench that treats the instruction as someone else's job is the bench that sees the specimen come back.
What should a respiratory bench record for a sputum specimen?
Six fields, and the one that is most often missing is the packaging declaration.
- The container and its lot. A sterile container carries a lot, and a failed sterility check traces back through it.
- The collection time. A specimen's age decides whether it is accepted, so the time is recorded at the point of collection.
- The specimen description. A specimen recorded as sputum and a specimen recorded as saliva are not the same test, and the description is what a laboratory reads first.
- The packaging declaration. Whether the specimen moved as a category B substance, and on which declaration, belongs with the record.
- The courier and the time handed over. A transport chain is only as good as its handover record.
- The reference. The section or rule that gives the class of the container, with the currency date of the text used.
Which consumables does a specimen bench restock?
A respiratory bench runs on the containers and transport packaging that carry a specimen to the laboratory. The 120 mL sterile screw-cap containers hold the primary receptacle, the sterile graduated specimen cups cover a smaller volume, and the double-tipped cotton swabs cover the sampling step. A laboratory that runs its own steriliser pairs the sterilization monitoring collection with the biological indicator 5-pack trial. 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. Reselling? become a distributor.
A record built on those fields answers a laboratory rejection and a transport question from the same page.

A specimen that is rejected for a paperwork gap is a specimen the patient gives twice. The printable specimen collection log is a free sheet with columns for the container lot, the collection time, the specimen description and the packaging declaration, so the acceptance criteria are checked before the courier arrives rather than after. The collection log generator sized to a respiratory clinic builds the sheet from the number of specimens a site collects in a week. No account and no sign-up are needed to open either one.
Where the class of a container or the packaging expected for a specimen needs to be set out for an inspection, a written answer is worth more than a general one. 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.
