Quick facts
- United States: a blood specimen collection device has a named entry at 21 CFR 862.1675, and the identification paragraph says the type "may include blood collection tubes, vials, systems, serum separators, blood collection trays, or vacuum sample tubes".
- United States: section 862.1675(b) places the device in Class II, one class above the general-purpose labware that surrounds it.
- Both countries: the order of draw comes from one standard, CLSI's order of blood draw tubes and additives, which both Canada and the United States follow because the standard is not national.
- Canada: Schedule 1 to the Medical Devices Regulations, SOR/98-282 names no collection tube. The tube that receives the specimen is a non-invasive device under the general rules, while the needle that penetrates the skin is a surgically invasive device under Rule 1(1) and is placed in Class II.
- Both countries: the tube itself is a container for venous blood, and the material specification sits in ISO 6710:2017, which covers single-use containers for venous blood specimen collection.
- The American text cited here was current at 2026-09-27; the Canadian regulation text is current to 2026-09-21.
A blood draw looks like one action and is really a sequence. The tube that is filled first takes the additive from the previous tube, and the additive that carries over is the one that changes a test result. The fix is an order of draw, and the order is written in a standard that is not national: the same CLSI sequence applies in a Toronto clinic and a Buffalo clinic. What differs between Canada and the United States is where the tube sits in the device framework, and that difference is larger than it looks.
Is a blood collection tube a device in both countries?
In the United States, yes and explicitly. In Canada the tube itself is not named, so the class is reached by a general rule.
The American entry is unusually broad. Section 862.1675(a) describes "a device intended for medical purposes to collect and to handle blood specimens and to separate serum from nonserum (cellular) components prior to further testing", and then lists what the type may include: "blood collection tubes, vials, systems, serum separators, blood collection trays, or vacuum sample tubes". The class is Class II.
Canada does not list a collection tube. A tube that receives blood does not penetrate the body, so it is not a surgically invasive device; it is a non-invasive device and is reached by the general rules. The needle is the invasive part, and Rule 1(1) places surgically invasive devices in Class II, which is where the Canadian class of the sharp end comes from. A practice that records the whole draw under one class is describing two devices as one.
For a lab buyer, the practical difference is that the American entry gives a named home for a vacuum tube system, while the Canadian file has to state which rule applies to which half of the draw.
| Item | Canada | United States |
|---|---|---|
| Named entry for a collection tube | None in Schedule 1 | 862.1675, blood specimen collection device |
| Route to the class for the tube | Non-invasive device under the general rules | The section states Class II |
| Route to the class for the needle | Rule 1(1), surgically invasive, Class II | Separate needle entries, for example 880.5570 |
| Named scope of the American entry | Not applicable | Tubes, vials, systems, serum separators, trays, vacuum tubes |
| Practical record | State the rule per half of the draw | State the section once |
Is the order of draw the same in Canada and the United States?
Yes, and this is the point most often missed, because the order is set by a standard rather than by a country.
CLSI publishes the sequence, and it is the same sequence on both sides of the border: a blood culture tube or bottle first, then the sodium citrate tube, then serum tubes, then heparin tubes, then EDTA tubes, then the sodium fluoride and potassium oxalate tube. The order is not a national requirement that one country wrote and the other adopted. It is a standard that both jurisdictions use, so a Canadian practice that follows the CLSI order is following the same document as an American one.
The part of the standard that is worth quoting is not the sequence but the reason for the first two positions. CLSI states that a "plastic serum tube containing a clot activator may cause interference in coagulation testing", and that "only blood culture tubes, glass nonadditive serum tubes, or plastic serum tubes without a clot activator may be collected before the coagulation tube". That sentence explains why a serum tube cannot simply be moved to the front of the line: the clot activator is the interference, and the tube that comes before the citrate tube has to be free of it.
| Order | Tube | Additive and purpose |
|---|---|---|
| 1 | Blood culture tube or bottle | Sterile draw, taken first |
| 2 | Sodium citrate | Coagulation testing, sensitive to carryover |
| 3 | Serum tube, red or gold | Clot activator; must not precede citrate |
| 4 | Heparin, green | Chemistry, avoids clotting |
| 5 | EDTA, lavender | Haematology, binds calcium |
| 6 | Sodium fluoride and potassium oxalate, grey | Glucose, inhibits glycolysis |
Why does the American entry put a specimen container in Class II?
Because the entry covers a system that separates serum from cells, not just a tube that holds liquid.
The identification paragraph names serum separators and vacuum sample tubes in the same list as the trays and the vials. A serum separator tube contains a gel and a clot activator, and the device is doing something to the specimen rather than only containing it, which is why the entry is written to cover the handling step as well as the collection step. That is the reason the class sits at Class II while the general-purpose labware around it sits at Class I.
Canada reaches the same function differently. A tube that separates serum from cells is still not penetrating the body, so the general rules apply rather than a named entry, and the class comes from the rule rather than from the function described in the product name. A Canadian file that describes a serum separator tube by its function is describing the device accurately but not the rule path.
What has to be recorded for a blood draw?
Six records, and the two that are most often merged are the tube and the additive.
- The order actually used. The sequence of tubes drawn, not the sequence the standard recommends, because a deviation is the thing an audit looks for.
- Each tube's additive. Recorded per tube, so a clot activator never appears on the same line as a citrate tube.
- The fill volume. Underfilled citrate tubes change the anticoagulant ratio, which is a specimen problem rather than a device problem.
- The lot numbers. Kept per tube type so a recall can be traced to the draws that used the lot.
- The time the specimen was drawn. The start of the transport clock and part of the acceptance criteria the receiving lab applies.
- The transport packaging. In Canada this is the federal dangerous goods packaging requirement that a receiving laboratory states in its acceptance criteria.
A draw record that keeps these six fields can answer a rejection question without re-drawing the patient.
Which consumables does a blood draw station restock?
A draw station runs on tubes, needles and transport packaging, and the three are ordered on one cycle. 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 sterile 15 mL centrifuge tubes cover the aliquoting bench, the winged infusion set covers the draw itself, and the 95 kPa specimen transport bags cover the step between the chair and the laboratory. A site that also runs its own steriliser can pair the monitoring collection with the biological indicator 5-pack trial.

A draw that cannot be documented is a draw that cannot be defended. The printable draw log is a free sheet with one row per tube, so the additive and the fill volume never share a field. The generator sized to a draw station builds the sheet from the number of draws a site performs and the tube types it holds, which keeps a single-chair clinic from being handed a reference-laboratory form. No account and no sign-up are needed to open either one.
Where the class of a tube or the acceptance criteria for a specimen need to be explained for an audit, 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
Is a blood collection tube a Class II device in the United States?
Yes. Section 862.1675 places the blood specimen collection device in Class II, and the identification paragraph states that the type may include blood collection tubes, vials, systems, serum separators, blood collection trays and vacuum sample tubes.
Is the order of draw different in Canada and the United States?
No. The order comes from the CLSI sequence, which is a standard rather than a national rule, so both countries follow the same order: blood culture first, then sodium citrate, then serum, then heparin, then EDTA, then sodium fluoride.
Why must a serum tube not be drawn before a citrate tube?
CLSI states that a plastic serum tube containing a clot activator may cause interference in coagulation testing, and that only blood culture tubes, glass nonadditive serum tubes or plastic serum tubes without a clot activator may be collected before the coagulation tube.
How is a collection tube classified in Canada?
There is no named Schedule 1 entry for a collection tube. The tube that receives the specimen is a non-invasive device under the general rules, while the needle that penetrates the skin is a surgically invasive device under Rule 1(1) and is placed in Class II.
Does an underfilled citrate tube matter?
Yes. An underfilled tube changes the ratio of blood to anticoagulant, which is a specimen problem that affects the coagulation result, so the fill volume belongs in the draw record beside the tube type.
What transport packaging does a Canadian lab expect?
Canadian acceptance criteria refer to the federal dangerous goods packaging requirement for specimens, along with a requirement that the specimen does not leak. Keeping the packaging type in the draw record lets a rejection question be answered without a re-draw.
