A specimen bag station is the fixed counter point where a collected sample is bagged, sealed and logged for transport. Setting it up well means four things: the right 95kPa bags within arm's reach, a labelling step that cannot be skipped, a secondary pack for transport, and a restock routine that runs before the rack empties. Get those four right and the station stops being a bottleneck on the morning run.
What belongs on a specimen bag station checklist?
Treat the checklist as four zones rather than a flat list. The collecting zone holds the primary containers and a marker; the bagging zone holds the 95kPa bags and an absorbent layer; the documentation zone holds the requisitions and a log; the transport zone holds the secondary pack and the seals. Each zone has its own consumables, and each needs a named owner for restocking.
Naming an owner matters more than the list itself. A checklist with no owner drifts for a week and then runs dry on the busiest morning of the month.
Which 95kPa bag sizes should a diagnostic lab stock?
| Bag size | Typical use | Stock level |
|---|---|---|
| 6 x 9 inch | Single tube or swab, outpatient draws | Highest turnover |
| 8 x 10 inch | Small panel of tubes plus requisition | Standard bench stock |
| 7 x 11 inch | Tall containers and urine cups | Medium |
| 12 x 15 inch | Multi-tube panels and transport totes | Lowest turnover |
Keep the two highest-turnover sizes at the station and the larger formats at the packing bench. A station that carries every size ends up with the 12 x 15 inch bags pushed to the back where nobody uses them.
How do you lay out the station so bags do not get mixed up?
Direction of flow does most of the work. Put the primary containers on the left, the bag rack in the middle and the transport pack on the right, so a completed sample moves in one direction and never crosses an unfinished one. Label each bag size on the rack itself, not on the box, so a refill does not put the 6 x 9 inch bags where the 8 x 10 inch bags belong.
Keep a marker and a spare pen at the station, not in the office. The single most common cause of a mislabelled specimen is a pen that walked away with the person who dropped off the last rack.
What labelling and documentation does a Canadian lab need at the station?
Every specimen bag carries the patient identifier, the collection date and the requested test, and the requisition travels in the same bag, not a separate envelope. Ontario labs also log the draw against the accession list at the point of bagging, so a missing tube is caught before the courier leaves rather than on the bench an hour later. The bag seal is part of the record: a broken seal on arrival is logged, not quietly re-bagged.
How often should the station be restocked and audited?
Restock to a par level each morning and audit the par weekly. The morning restock refills the rack; the weekly audit checks that the par level itself is still right by comparing bags used against bags ordered. If the 6 x 9 inch bags run out twice a week, the par is too low, and no amount of manual topping up fixes a par that was set on an old census.

Frequently Asked Questions
What size 95kPa bag is used most in a diagnostic lab?
The 6 x 9 inch bag turns over fastest because it handles single-tube and single-swab draws, which are the bulk of outpatient work. The 8 x 10 inch size is the standard bench stock for small panels, and the larger formats are kept at the packing bench instead of the station.
How many specimen bags should a station hold?
Set a par of one week of use and restock daily. A station processing 200 draws a week would hold around 250 of the main size so the rack never empties on a heavy morning, with the balance held in the storeroom.
Do specimen bags need a separate absorbent layer?
Yes, for liquid specimens. The absorbent layer in a 95kPa transport bag soaks up any leak so the outer packaging stays clean, which is what keeps the shipment within transport rules if a tube cracks in transit.
Can a specimen bag be reused if it is unopened?
No. Bags are single-use, and an opened rack should be sealed and dated rather than returned to stock. Reusing a bag breaks the chain between the draw and the accession record.
