HR On-Site Drug Testing Checklist
A practical pre-event guide for HR and operations—roster, test reason, employee flow, collection space, and closeout before collection day.
An onsite testing event runs well when HR, operations, and the collection team are working from the same plan. Without that alignment, people wait, managers scramble, and paperwork gets harder to reconcile afterward.
Use this checklist before mobile drug testing or on-site collection day. Keep your policy, TPA instructions, and DER decisions as the source of truth for program authority.
Use this checklist before collection day
An onsite testing event runs well when HR, operations, and the collection team are working from the same plan. Use this checklist before the event so employees move through the process cleanly and the paperwork is easier to manage afterward.
Print it, share it with your site lead, and confirm each item with your DER or TPA when DOT donors are involved. The goal is fewer surprises on the day collectors arrive.
1. Confirm who is being tested
Build a final roster with:
Full names
Shift timing
Department or location
Any late additions clearly marked
If your site has both DOT and non-DOT employees, separate those groups before the event starts. Mixed rosters are a common source of wrong forms and wrong test reasons. See DOT and non-DOT separation before you finalize the list.
2. Confirm the test reason and modality
Do not stop at "drug test." Confirm:
Pre-employment, random, post-accident, reasonable suspicion, or other reason
Drug only, alcohol only, or both
Urine, oral fluid, or other approved modality
Any observation requirements already identified by the program
Share this with your scheduling contact early so collectors bring the right supplies, forms, and staffing assumptions.
3. Build the employee flow
Decide:
Who releases employees
How many employees report at once
How completions are tracked
How no-shows are handled
Who covers the department while employees are testing
This is where most event-day bottlenecks start. A release plan by shift beats sending an entire department at once when coverage is thin.
4. Prepare the collection space
Choose a space with:
Privacy
Low foot traffic
Check-in room
Restroom access if urine testing is ordered
A clear path for donors to report and exit
Confirm the space is reserved for the full testing window—not a conference room that gets double-booked at noon.
5. Send the employee message
Keep the message short:
Where to report
When to report
What to bring (usually government-issued photo ID)
What to expect on timing
Who to contact with operational questions
Keep the tone neutral and professional. Supervisors should not debate policy in the employee announcement.
6. Assign one lead and one backup
Name one primary site contact and one backup. The collector should not have to search the building for a decision-maker once the event starts.
The lead coordinates check-in, answers operational questions, and escalates program decisions to the DER when needed. The backup covers breaks, production fires, and handoffs without leaving the collection area unsupported.
7. Prepare closeout steps
After the event:
Note completions
Note no-shows
Document follow-up items
File the event details the same day
Confirm any open issues with HR or the TPA
Closeout while details are fresh. Waiting until the next shift invites roster drift and missed follow-ups for donors who still need to test.
Quick FAQ
What is the most common day-of problem?
Poor employee flow. Too many donors released at once, no one tracking completions, and no backup coverage for the line are the usual causes of delay—not the collection itself.
Should DOT and non-DOT employees be separated?
Yes, always. Separate them on the roster, in scheduling blocks, and in supervisor instructions so collectors receive one clear program per donor.
How early should HR prepare the roster?
As early as possible, with a final version confirmed before the event. Send a draft when planning starts, then lock names, DOT flags, and test reasons before collection day.
