A specimen is rejected far more often for what happens after the draw than for the draw itself: label at the chair, seal the bag without reopening it, respect the storage window, and sign the handoff.
Post-Collection Specimen Handling: A Canadian Clinic Checklist from Draw to Lab
A specimen is only as good as the steps after the draw. The tube itself can be handled perfectly and still arrive unusable because of a label written late, a bag opened to add a form, or a delay that stretched past the window. A short checklist keeps those steps from drifting.
What is the checklist from draw to lab?
Six steps carry a specimen from the chair to the courier. Each one has an owner and a moment, which is what makes a checklist worth having:
| Step | Owner | The check |
|---|---|---|
| Draw | collector | correct tube, filled to the line |
| Label | collector | identifiers and collection time, applied at the chair |
| Pack | collector | one specimen per bag, form in the document pouch |
| Store | station | temperature the test calls for |
| Handoff | sender | signed record against the courier |
| Receipt | lab | confirmation the sample arrived intact |
The step that fails most often is the second one, because labelling is easy to defer and impossible to reconstruct later.
Why does labelling decide the outcome?
The label is what the lab matches against the requisition. If the identifiers disagree, or the collection time is missing, the sample is set aside rather than tested. Write the label at the point of collection, before anything else is done with the sample, and use a pen that does not smudge on a cold tube. Two identifiers plus the collection time is the working standard, and it is the same information the requisition already carries.
How should the specimen be packed?
One specimen per bag. The requisition goes in the pouch so it can be read without opening the sample compartment, and the absorbent pad sits inside to take up a small leak. Seal the bag and leave it sealed. A specimen transport bag is built with those three elements for a reason, and a leak-proof sample cup covers the volume specimens that go inside it. For stool, sputum and other samples moved by ground, a three-wall transport bag adds a leak-resistant layer between the sample and the outside.
Where should specimens wait?
Held at the temperature the test calls for rather than on the nearest bench. Many routine draws want a fridge; some want room temperature; and a few are time-critical enough that the collection time on the label decides whether the sample is usable at all. Keep specimens in a designated spot away from food and open surfaces. In a care home, O. Reg. 246/22 sets general expectations for safe handling in the home, and a defined specimen spot is the practical expression of it. A small rigid container or a dedicated fridge shelf is enough; the point is that the location is always the same.
Who signs the handoff?
The person who hands the specimens to the courier, against a count. A signature is not bureaucracy here: it is what lets a clinic answer the question "where did sample X go" without guessing. The receiving lab confirms what arrived, and a mismatch between the two records is how a lost sample is caught early rather than discovered by a patient.
A printable draw-to-lab checklist
The free printable template at the compliance log centre holds the six steps, the owner at each one and the handoff signature, so the routine is written down rather than remembered.
A handling routine planner
The handling routine planner sets the storage temperature and the timing window beside each test, which is the sheet to review when a clinic adds a new assay.

Frequently Asked Questions
What happens to a specimen after the draw?
It is labelled at the point of collection, packed with the requisition in a separate document pouch, held at the temperature the test calls for, and handed to the courier or lab against a record. Each step is a place where a sample is either kept intact or lost.
Why are specimens rejected?
Rejection usually comes from a labelling or timing problem rather than the test itself: an unlabelled or mismatched tube, a requisition that does not match the sample, a delay beyond the acceptable window, or a container that leaked in transit.
How should specimens be packed for transport?
One specimen per bag, requisition in the document pouch, absorbent pad inside, and the bag sealed so it is not reopened. Bulkier samples go in a larger transport bag or a rigid container rather than being forced into a small one.
Does a clinic need a written specimen-handling procedure?
Yes, if a clinic collects and sends specimens. A one-page procedure that names who labels, who packs, where specimens wait and who signs the handoff is enough, and it is the document an inspector asks for.
