Sample transfer to contract laboratory process flowchart
An editable sample transfer workflow for planning an external laboratory handoff, preparing identifiers and records, confirming receipt, resolving issues and tracking follow-up.
What the sample transfer to contract laboratory process is
The flow begins by confirming the destination, transfer instructions and receiving contact before a sample is prepared. It keeps the sample identifier, handoff record and timing visible because a transport event can change what the receiving laboratory is able to do next.
Preparation, dispatch and receipt each have an exception path. Missing information, an unsuitable handoff or an issue reported at receipt returns to the people who can clarify, replace or escalate the transfer rather than being silently treated as a completed delivery.
Use the chart with the local arrangements that govern packaging, conditions, carriers, chain of custody and sample acceptance. It does not prescribe those controls or imply that external handling follows the same procedure as local testing.
What this flowchart covers
In this template
- Confirming transfer instructions, destination and receiving contact before a sample leaves the sending team.
- Preparing the sample, identifiers and transfer record as one connected handoff package.
- A receipt-confirmation path that makes a delivery issue visible to both laboratories.
- Replacement, clarification and escalation routes before the external work is treated as ready to proceed.
When to use this template
- You send samples to a contract laboratory for specialist testing, overflow capacity or another defined service.
- Sending, logistics and receiving teams need an explicit record of who owns the sample at each handoff.
- You want an editable process that exposes incomplete records or receipt issues before testing begins.
How it works
Map the actual handoff
Replace the lane names and transfer steps with the people, carrier arrangements, records and communication channels your organisation uses. Include the point where responsibility changes hands.
Define local transfer conditions
Add the packaging, timing, identification, storage and notification requirements that apply to the sample and destination. Those details belong to your own approved instructions, not to a generic template.
Practice a receipt exception
Walk through a delayed delivery, mismatched identifier or reported condition concern. Confirm who records the issue, who decides the next action and how a replacement or escalation reconnects to the transfer record.
Frequently asked questions
What does a sample transfer to contract laboratory process flowchart cover?
It covers planning the external handoff, checking instructions, preparing the sample and transfer record, arranging dispatch, receiving confirmation, issue handling and the follow-up needed before testing can continue.
Why is receipt confirmation a separate step?
Dispatch only shows that the sending team released a package. Receipt confirmation records what the destination received and whether it reported an issue that changes the next action. Keeping those events separate prevents a delivery status from being mistaken for a usable testing handoff.
Can this template define sample packaging or transport criteria?
No. Appropriate conditions depend on the sample, service, route, carrier, destination and local instructions. Use the chart to show where those requirements are checked and recorded, then add the specific rules your organisation has established.
