Laboratories are built on data.
Every day, laboratory leaders measure performance to improve quality, productivity, and patient outcomes.
They monitor:
But when it comes to specimen transportation, many organizations have far less visibility.
It's not uncommon for laboratories to know exactly how long it takes to process a specimen once it arrives at the lab—but have very little insight into what happened before it got there.
That's a missed opportunity.
Specimen transportation is the first step in the diagnostic process, and like every other critical operation, it should be measured.
The question is:
Which metrics actually matter?
It's easy to collect transportation data.
It's much harder to identify the information that helps you make better operational decisions.
Many laboratories know how many pickups were completed yesterday.
But that doesn't answer more important questions such as:
The best logistics metrics don't simply tell you what happened.
They help explain why it happened.
If there is one transportation metric every laboratory should understand, it's turnaround time.
Turnaround time measures the total time required for a specimen to move from the collection site to the laboratory.
Unlike simple "on-time" reporting, turnaround time reflects the overall performance of the transportation process.
It helps answer questions such as:
Without measuring turnaround time, it's difficult to understand how efficiently your logistics operation is performing.
For many laboratories, on-time pickup performance is especially important for STAT specimen transportation.
When a STAT pickup is requested, laboratory staff expect the courier to respond within a defined service window.
If the courier is running behind, uncertainty begins almost immediately.
Questions start coming in.
In many cases, laboratory staff begin calling the courier simply because they don't know what's happening.
That's why on-time pickup performance is such an important metric.
It serves as an early indicator that urgent specimens are moving through the transportation process as expected.
Just as importantly, it gives laboratory staff confidence that patient care isn't being delayed.
Picking up a specimen on time is only part of the process.
Laboratories also need to know whether specimens are arriving within the expected delivery window.
This is particularly important for:
Consistently meeting delivery commitments helps laboratories maintain predictable workflows and begin testing as planned.
For routine specimen transportation, route performance is one of the most valuable operational metrics.
This isn't simply about how fast a route is completed.
It's about whether the route is being executed correctly.
Consider a physician's office with a scheduled pickup after 5:00 PM.
If a courier arrives too early and leaves before the day's specimens are placed in the lockbox, those specimens may remain overnight.
That can result in:
Laboratories should monitor questions such as:
Route performance is about consistency—not just speed.
Understanding specimen volume by collection site provides valuable operational insight.
It helps laboratories identify:
This metric supports both transportation planning and business development.
For example, if a physician's office that historically submitted large specimen volumes suddenly begins sending very few—or none at all—it may indicate a service issue, a workflow change, or a shift in referral patterns that deserves attention.
Chain of custody is much more than confirming a specimen was delivered.
It's about documenting every handoff throughout the transportation process.
One of the most valuable metrics laboratories can monitor is scan compliance.
Each pickup, transfer, and delivery should be confirmed through barcode scans or another documented tracking method.
Laboratories should also monitor exception reporting, often referred to as Over, Short, and Damaged (OS&D) reports.
For example:
Or:
These discrepancies help identify missing specimens, unexpected additions, or documentation gaps before they become larger operational problems.
Strong chain-of-custody metrics provide confidence that every specimen has been properly accounted for throughout its journey.
Many laboratories know what they spend on transportation each month.
Far fewer know the average cost of each pickup or delivery.
Understanding cost per pickup helps laboratories evaluate:
When viewed alongside specimen volume and route performance, this metric provides a much clearer understanding of transportation efficiency.
Collecting transportation metrics isn't the goal.
Using them is.
For example:
If turnaround times begin increasing...
Why?
If STAT pickups are consistently late...
What's causing the delay?
If routes are taking longer than expected...
Is the issue traffic, scheduling, or route planning?
If scan compliance begins decreasing...
Is there a training issue?
The best metrics don't simply create reports.
They create conversations that lead to operational improvements.
Ultimately, the most important metric isn't a number.
It's visibility.
Can your leadership team confidently answer questions such as:
If the answer is yes, you're in a much stronger position to improve performance.
If the answer is no, visibility—not transportation—is likely your biggest opportunity.
Many laboratories ask:
"What logistics metrics should we track?"
A better question is:
"Do our logistics metrics give us confidence that our transportation operation is performing the way we expect?"
The strongest laboratory logistics programs don't collect metrics simply to build reports.
They collect metrics that help identify problems before they affect laboratory operations or patient care.
Because the real value of transportation metrics isn't measuring yesterday's performance.
It's providing the visibility needed to improve tomorrow's.
Transportation is one of the most important—but least measured—parts of laboratory operations.
The strongest laboratory logistics programs don't collect data for the sake of reporting.
They measure what matters.
When laboratories understand their transportation metrics, they gain more than numbers.
They gain visibility.
And visibility allows organizations to improve efficiency, strengthen accountability, protect specimen integrity, and ultimately deliver better patient care.
Some of the most valuable metrics include turnaround time, on-time pickup performance, on-time delivery performance, route performance, pickup volume by location, chain-of-custody performance, and cost per pickup or delivery.
Turnaround time measures the total time required to transport a specimen from collection to the laboratory, providing a more complete picture of transportation performance than on-time reporting alone.
For STAT specimens, on-time pickups provide confidence that urgent specimens are moving quickly toward the laboratory and help identify transportation delays before they impact patient care.
Route performance evaluates whether routine collection routes are being completed as scheduled, including whether couriers arrive within the correct pickup window—not too early and not too late.
Chain-of-custody performance measures how consistently specimens are documented throughout transportation using scans, tracking events, and exception reporting to ensure accountability.
An Over, Short, and Damaged (OS&D) report identifies discrepancies between the number of specimen bags or containers expected and the number actually received, helping laboratories quickly identify transportation exceptions.
Tracking specimen volume by collection site helps laboratories optimize routes, allocate resources, identify growth opportunities, and recognize changes in provider activity.
Meaningful logistics metrics improve visibility into specimen movement, reduce transportation delays, strengthen accountability, and help laboratories deliver timely and reliable diagnostic results.
