DOT Oral Fluid Collector Training & Qualification — 49 CFR §40.35
DOT Oral Fluid Collection — Introduction
DOT oral fluid collection became authorized in 2023 and codified in 49 CFR §40.35. As a qualified oral fluid collector, you supervise the donor through a device-specific procedure that's simpler than urine — but every step still matters. This module covers everything under Part 40 Subpart F.
What This Module Covers
- The DOT oral fluid program — §40.35 and the OFMG
- Device-specific qualification (not "general" qualification)
- Oral cavity inspection and the Volume Indicator(s) Observed (VIO) requirement
- Supervised collection — what "personally observe" means
- Insufficient fluid (dry mouth), refusal, tampering
- Your §40.35 training and documentation
Who This Is For
Existing DOT collectors adding oral fluid to their qualification, and new collectors entering the field with oral fluid first. Either way: you qualify per device.
Regulatory Context
DOT oral fluid testing is governed by 49 CFR Part 40 (alongside urine), but qualification, devices, and procedures are device-specific under §40.35. The HHS Oral Fluid Mandatory Guidelines (OFMG) determine which devices may be used.
Authorization Timeline
- May 2, 2023 — DOT final rule authorizing oral fluid testing published
- June 1, 2023 — Rule effective; implementation conditional on HHS OFMG completion
- Pending — HHS certification of testing laboratories under OFMG; once two labs are HHS-certified for oral fluid, DOT employers can use oral fluid as a primary specimen choice
When DOT Allows Oral Fluid
Per §40.13 and §40.35, oral fluid is allowed when:
- A shy-bladder situation requires an alternative
- The employer has chosen oral fluid as the methodology
- Direct observation is required and the donor refuses observed urine
- The donor has a documented anatomical / medical reason
The Major Differences from Urine
| Element | Urine | Oral Fluid |
|---|---|---|
| CFR section | §40.33 | §40.35 |
| Qualification | Single procedure | Per-device |
| Site | Restroom required | Any private area |
| Observed default | Same gender | Always supervised |
| Volume | 45 mL | Device VIO |
| Temperature check | 90–100°F @ 4 min | Not applicable |
| Bluing required | Yes | No |
The Collector
A DOT oral fluid collector is a trained person qualified to perform oral fluid collections using a specific OFMG-approved device. §40.35 makes you device-qualified, not generally qualified — you must complete proficiency for each device you use.
§40.35 Collector Definition
A trained collector who supervises the donor through an OFMG-approved oral fluid device — from cavity inspection through device removal, sealing, and CCF completion.
Who CANNOT Be a Collector
Same exclusions as urine:
- 1The donor's immediate supervisor (limited exception applies)
- 2A safety-sensitive co-worker
- 3An HHS lab employee who can link donor to result
- 4The donor themselves
Device-Specific Qualification
You're qualified only for the device(s) you trained on. Adding a new oral fluid device = new proficiency mocks for THAT device.
DER Contact Information
Required just like urine — name + phone, with C/TPA if applicable. Keep available for problem collections.
The Collection Site
Oral fluid collections are simpler to set up than urine — no toilet, no bluing, no flushing. But site privacy, security, and supervised collection rules still apply.
What's Required
- 1A private area where only you and the donor are present
- 2Adequate lighting for cavity inspection
- 3A clean work surface for the CCF and supplies
- 4Handwashing facility available
- 5No food, drink, or chewable items within reach of the donor
What's NOT Required (vs. Urine)
- — No toilet
- — No bluing agent
- — No water source sealing
- — No removal of soap/disinfectants
Security While in Process
- Donor under your continuous observation
- No access to anything that could contaminate device or oral cavity
- Sealed device pouches stored secure prior to use
- Specimens secured pending shipment
Supplies & Devices
You can only use an oral fluid collection device that appears on the HHS-approved list under the Oral Fluid Mandatory Guidelines (OFMG). The CCF, leak-resistant bag, and shipping container all must match the device.
OFMG-Approved Device
Only HHS OFMG-certified devices may be used for DOT collections. The device determines:
- Specimen volume (Volume Indicator(s) Observed signal)
- Wait time inside the cavity
- Number of pads / specimens (split A/B configuration)
- Sealing and transport requirements
Required Supplies
- OFMG device in tamper-evident packaging
- Federal CCF with the Oral Fluid box checked
- Leak-resistant bag (per device IFU)
- Shipping container
- Gloves and PPE
Device IFU
Manufacturer's Instructions for Use are part of compliance — they're device-specific and supplement (don't override) Part 40. Keep a copy at the collection site.
The Federal Oral Fluid CCF
The Federal CCF used for oral fluid is the same 5-part form as urine but with the oral fluid box checked. Specific fields apply to oral collections — Volume Indicator(s) Observed is the most important.
CCF for Oral Fluid
Same 5-part CCF, with the Specimen Type: Oral Fluid box checked in Step 1. All five copies are distributed exactly as with urine.
Volume Indicator(s) Observed (VIO)
Step 2 of the CCF has a specific check box for "Volume Indicator(s) Observed." This confirms the device collected sufficient oral fluid per the manufacturer's spec.
The 5 Steps of the CCF (Oral Fluid)
Step 1 — Collector / Employer
Same fields as urine. Check Oral Fluid as Specimen Type.
Step 2 — Collector (after specimen)
Check VIO. Indicate Split (A/B per device). Document anomalies in Remarks.
Step 3 — Seals
Seal device tubes / pouches. Donor initials each seal.
Step 4 — Collector Certification
Signature, time, date, delivery service.
Step 5 — Donor Certification
Donor signs, dates, prints, phone numbers.
Employer Information
Before you start, the employer (or C/TPA) must provide everything you need to fill out Step 1 of the CCF. Same set as urine — different test type box.
Required Information
- Full name of donor
- Donor SSN or employee ID
- Lab name and address (OFMG-certified)
- Employer name, address, phone, fax
- DER name + telephone (and C/TPA)
- MRO name, address, phone, fax
- DOT Agency
- Reason for test
- Specimen type: Oral Fluid
Donor ID & Eligibility
Donor identity verification for oral fluid is identical to urine. The donor must produce acceptable photo ID at the start. The donor must also be eligible for an oral collection — no recent food, drink, smoke, or chew.
Acceptable ID
Identical to urine — government photo ID, employer photo badge, or in-person ID by an employer representative.
Oral Cavity Eligibility — 10-Minute Wait
Before the device goes in, confirm the donor has not (within last 10 minutes):
- ! Eaten
- ! Drunk anything except plain water
- ! Smoked or used tobacco / chew
- ! Placed anything in their mouth (gum, mints, etc.)
Oral Cavity Inspection
- Donor opens their mouth wide
- Tongue raised and lowered
- Inside of cheeks (both sides)
- Document any foreign objects or substances
The Oral Fluid Collection
The collection is supervised — you watch the device in the donor's mouth from insertion to removal. Steps follow §40.35 plus the device manufacturer's IFU (Instructions for Use). Device-specific timing applies.
The Oral Fluid Procedure
Prepare the Site & Supplies
Device, CCF, gloves ready.
Verify Identity
Photo ID. No ID → contact DER.
Explain Procedure
Walk through the device, the wait time, the VIO indicator. Show the donor the back of the CCF.
Complete CCF Step 1
Check Oral Fluid as specimen type.
10-Minute Eligibility Check
Nothing in the mouth for 10 minutes. Wait if needed.
Cavity Inspection
Visualize tongue, cheeks, oral floor. Document.
Open the Device
You break the seal in donor's view (or both unseal simultaneously per IFU).
Donor Places Device
Per IFU. You watch insertion.
Observe Throughout Wait
Eyes on the device the entire collection period. No tampering, no movement out of view.
Confirm VIO
When the volume indicator triggers, removal is permitted.
Removal
Donor removes per IFU; you observe.
Process Specimens
Place into transport tubes per IFU. Apply seals. Donor initials seals.
Complete CCF
Step 2 (VIO check), Step 4 (you), Step 5 (donor).
Distribute Copies
Copy 5 to donor. Copy 1 with the specimen. Others per usual.
Package & Ship
Leak-resistant bag, shipping container, sealed and dispatched.
When Things Go Sideways
The most common oral fluid disruptors are dry mouth (insufficient oral fluid), refusal, and tampering attempts. Each has a defined protocol under §40.35 and Part 40 Subpart F.
Insufficient Oral Fluid (Dry Mouth)
If the VIO does not trigger within the device's allowed time:
Discontinue first attempt
Document in Remarks (start time).
Fluid period
Donor may drink up to 8 oz of water, distributed over up to 15 minutes.
Second attempt
New device, second 10-minute wait, full procedure.
If still insufficient
Stop. Document. Notify DER. Employer arranges medical evaluation.
Refusal Triggers
- ! Refuses cavity inspection
- ! Refuses to drink water during fluid period
- ! Leaves the site before collection complete
- ! Refuses to initial seals
- ! Found tampering with device
Fatal Flaws
- ! Specimen ID mismatch (device vs CCF)
- ! No collector signature on Step 4
- ! Seals broken on arrival
- ! No specimen received with the CCF
- ! VIO not observed and not documented as insufficient

Best Practices
Oral fluid collection looks easier — and that's where collectors get tripped up. Skipping the cavity inspection, missing the Volume Indicator(s) Observed box, or rushing the wait time will kill the test.
Top 10 Oral Fluid Mistakes
- 1Skipping the 10-minute eligibility check ("they look fine")
- 2Failing to inspect the cavity properly
- 3Letting the donor handle the device out of view
- 4Not checking the VIO box on the CCF
- 5Removing the device early — before VIO triggers
- 6Letting the donor drink more than 8 oz during fluid period
- 7Mixing devices — qualifying on Device A then collecting with Device B
- 8Forgetting the donor initials on seals
- 9Sealing pouch backwards (specimen/CCF swapped)
- 10Not following the device-specific IFU
Best Practices Checklist
- Treat the 10-minute clock as the start of the collection
- Cavity inspection in good lighting — every time
- Eyes on the device through the entire wait
- VIO box is the most-skipped item — make it a habit
- One device, one CCF — never mix kits
- Follow §40.35 + the device IFU together
