DOT Oral Fluid Collector Training & Qualification — 49 CFR §40.35
DOT Oral Fluid Collection — Introduction
Oral fluid is authorised as a DOT specimen type by §40.210 — “Both urine and oral fluid specimens are authorized for collection and testing under this part.” The collection procedure itself sits at §§40.72–40.74, the device and kit requirements at §40.49 and appendix B, and §40.35 is your collector qualification section. (§40.35 does not authorise the methodology, and §40.13 is about keeping DOT and non‑DOT tests separate — neither is the authority for using oral fluid.) 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. Oral fluid requirements are integrated throughout Part 40 — there is no separate oral fluid subpart. (Subpart F is Drug Testing Laboratories.)
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 quantity, something in the mouth, tampering, refusal to sign the CCF
- 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. The HHS Oral Fluid Mandatory Guidelines already exist — what is outstanding is not their “completion” but HHS certification of laboratories to test oral fluid specimens under them
- Still pending as of August 2026 — DOT oral fluid testing cannot begin until HHS has certified at least two laboratories to test oral fluid specimens (one to test, one to serve as the split-specimen laboratory). Verify the current status yourself before telling a client oral fluid is available — check the HHS/SAMHSA certified-laboratory list and ODAPC’s notices, not this page. This is a live regulatory status that can change after the date above.
When DOT Allows Oral Fluid
Per §40.210 and §40.67(g), oral fluid is allowed when:
- The employer has chosen oral fluid as the methodology for the testing event
- A collection problem necessitates a second collection (insufficient urine, temperature out of range, insufficient saliva) and the employer — by standing order or a discussion with the collector — chooses the other specimen type (§40.210). The collector does not make this call alone
- A same-sex observer cannot be found for a required observed urine collection, once oral fluid testing is available (§40.67(g)(4))
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 sex | 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 conforming device. §40.35(b)(2) requires training to proficiency in the operation of the particular device(s) you will be using — so you are device-qualified, not generally qualified, and you must complete proficiency for each device you use.
§40.35 Collector Definition
A trained collector who supervises the donor through a conforming oral fluid collection 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 — a conflict‑avoidance recommendation, not a §40.31 prohibition
- 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. §40.73(a)(1) is framed around who may actually witness the testing process — you, the employee, or a DOT agency representative — rather than a blanket rule that exactly two people may be in the room at all times
- 2Adequate lighting for the oral-cavity inspection — a practical requirement and a device-IFU consideration; Part 40 does not specify lighting
- 3A clean work surface for the CCF and supplies
- 4Hand sanitizer or handwashing available — §40.72(d)(6) lets the donor use sanitizer or wash and dry their hands
- 5No food, drink or chewable items within reach of the donor — TestRight contamination-control practice. Part 40’s requirements here concern the oral-cavity inspection, waiting-period conduct, device procedure and observation; it does not enumerate this as a site requirement
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 may only use a conforming oral fluid collection device. Be precise about what that means: HHS does approve devices — but only paired to a laboratory. Appendix B to Part 40 requires that a device “be approved by HHS for use by the specific HHS-certified laboratory that will test the specimen gathered by this device.” What does not exist is a free-standing, universal device approval you could rely on with any laboratory. Instead, Appendix B to Part 40 sets out the design and performance criteria a device and kit must meet, and the device must produce a specimen that the HHS-certified laboratory you ship to can actually analyze. In practice: use the device your laboratory accepts, confirm it meets Appendix B, and train to proficiency on that specific device.
What Makes a Device Conforming (Appendix B)
You must use an HHS-certified oral fluid laboratory and a collection device approved by HHS/NLCP for use with that laboratory. “OFMG-certified” is not the right description — OFMG is the HHS Oral Fluid Mandatory Guidelines; laboratories are certified through the NLCP. 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 Federal form as urine, with the oral fluid box checked. It may be the paper five‑part carbonless manifold or an electronic CCF (§40.40(c)(5), (f)); either way it must be a Federal CCF version currently authorised by DOT/HHS (§40.40(a)–(b)) — “unexpired” is the wrong test during the transition. The revised 2026 Federal CCF took effect 27 April 2026 and may be paper or electronic; the 2023 CCF may still be used, and its use requires no MFR through 30 May 2027, but from 31 May 2027 it requires an MFR under §40.205(b)(2) (ODAPC guidance). Specific fields apply to oral collections — Volume Indicator(s) Observed is the most important.
CCF for Oral Fluid
Same Federal CCF as urine — paper five‑part carbonless or electronic. §40.72(d)(4) directs the collector to complete Step 2 — that is where Oral Fluid as specimen type and the Subdivided indication go. The device expiration date is recorded in Step 4 (§40.72(d)(5)); because one device collects a single specimen that is then subdivided in front of the donor, you make only one expiration entry. Step 1 remains the employer/donor/MRO information. 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: donor, employer/DER, MRO, agency, reason for test. The specimen-type box is not here — it is in Step 2 (§40.72(d)(4)).
Step 2 — Collector (mostly BEFORE the specimen)
Under §40.72(d)(4) the Step 2 entries — “Oral Fluid”, Split Type “Subdivided”, “Each Device Within Expiration Date?” — are completed during the 10-minute wait, before collection, and the device expiration date goes in Step 4 at that same point (§40.72(d)(5)). Only the Volume Indicator(s) Observed entry is made after a sufficient specimen is obtained. 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 (an HHS-certified laboratory for oral fluid testing)
- 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 & Oral Cavity Check
Donor identity verification for oral fluid is identical to urine. What follows it is not an “eligibility” question about what the donor did in the last ten minutes — §40.72 sets a specific order: inspect the oral cavity first, then rinse and wait only where the rule calls for it.
Acceptable ID
Identical to urine — government photo ID, employer photo badge, or in-person ID by an employer representative.
Step 1 — Inspect the Oral Cavity (§40.72(a))
You ask the employee to open their mouth, and you inspect it for anything that could impede or interfere with the collection, or that could be used to adulterate, substitute or alter the specimen — candy, gum, food, tobacco.
- If you see an indication of any of that, ask them to lift the tongue and/or separate cheek from gum for a full inspection. They may cleanse their hands, but they must not decline the further inspection
- If they claim a medical condition prevents opening their mouth, follow §40.193(a)
- Document what you observed
Step 2 — Rinse and Wait, When the Rule Calls For It
An item present that might interfere? Ask the employee to remove it. Then §40.72(b)(1) applies if any one of these is true:
- They removed an item that could impede or interfere
- Their saliva is abnormally colored
- They claim dry mouth
If the employee refuses to remove the item or to rinse: terminate, note the circumstances in Remarks, and report to the DER as a failure to cooperate (§40.191(a)(8)) — again, the employer makes the refusal determination.
Step 3 — Nothing of Concern? Still Wait 10 Minutes (§40.72(c))
If there is nothing of concern in the oral cavity and no dry-mouth condition, you start a 10-minute wait and then collect. The wait applies either way — what changes is whether a rinse comes first.
The Oral Fluid Collection
The collection is supervised — you watch the device in the donor's mouth from insertion to removal. Steps follow §40.72 (the collection procedure), with sealing and completion under §40.73–§40.74, plus the device manufacturer's IFU (Instructions for Use). §40.35 is the collector qualification section — do not cite it for operational steps. 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.
Inspect the Oral Cavity — This Comes First
Employee opens their mouth; you inspect for anything that could impede the collection or be used to adulterate, substitute or alter the specimen (§40.72(a)). Lift the tongue / separate cheek from gum if indicated. Document what you saw. Conduct clearly indicating tampering → terminate, note in Remarks, report to the DER — the employer decides refusal.
Item Present? Remove, Then Rinse
If an item that could interfere is removed, or the saliva is abnormally colored, or the employee claims dry mouth — you must give water, up to 8 ounces, to rinse the mouth (§40.72(b)(1)). They may drink it. Refusal to remove or rinse → terminate, note, report to the DER.
Wait 10 Minutes
You start a 10-minute wait before beginning the collection — after the rinse under (b)(1), or straight away where nothing of concern was found (§40.72(c)). The wait applies either way. It is not a look-back at the employee’s previous 10 minutes.
During the wait — §40.72(d), in this order
§40.72(d) sets six things to do inside the 10-minute wait, and the order is part of the rule — do not scatter them:
- (d)(1) Review the manufacturer’s instructions for the device with the employee.
- (d)(2) Complete all of Step 1 of the CCF — including the DOT agency check mark in Step 1.D and the collection site address in Step 1.G.
- (d)(3) You provide, or the employee selects, a device that is clean, unused and still wrapped or sealed. Check the expiration date and show it to the employee. Never use an expired device. Then you open it in the employee’s view — the employee does not open it.
- (d)(4) Complete Step 2: check “Oral Fluid”, check Split Type “Subdivided”, and check “Each Device Within Expiration Date?”
- (d)(5) Enter the Split Specimen Device Expiration Date in Step 4. One device, one entry.
- (d)(6) Instruct the employee to use hand sanitizer, or to wash and dry their hands. This is a required instruction, and it is the last thing before the collection begins.
Note where Steps 2 and 4 sit: both are completed before the employee provides the specimen, not after. Only the volume-indicator confirmation is recorded once the specimen has been provided.
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
Record the volume indicator observed confirmation, then the remaining collector and donor entries. The Step 2 device/split entries and the Step 4 expiration date were already completed during the wait period under §40.72(d)(4)–(5) — only the volume confirmation belongs here.
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 §40.72 and §40.193 (§40.35 governs collector qualification, not these procedures).
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).
Offer fluids — only if the donor says it would help
If the employee cannot provide after 15 minutes of using the device and says they could after drinking, urge them to drink up to 8 oz and wait an additional 10 minutes before the next attempt. Drinking is optional — if they simply need more time, they are not required to drink anything, and declining to drink is not a refusal (§40.193(b)(2)(i)).
Up to one hour total
A period of up to one hour must be provided from the first unsuccessful attempt, or until a sufficient specimen is provided. The employee must remain at the collection site in a monitored area you designate.
If still insufficient after one hour
Discontinue, note it on the “Remarks” line of the CCF (Step 2), and immediately notify the DER. The DER — after consulting the MRO — directs the employee to obtain an evaluation within five days from a licensed physician acceptable to the MRO (§40.193(b)(2)(ii) and (c)).
Refusal Triggers
- ! Refuses cavity inspection
- ! Leaves the site before collection complete
- ! Employee conduct — materials brought to the site, or behaviour, that clearly indicates an attempt to adulterate, substitute or alter the specimen. You terminate, note the circumstances in Remarks and report to the DER; the employer decides whether it is a refusal (§40.72(a)(3), §40.73(b)). This is different from an observation about the specimen or device after collection, which follows the laboratory/MRO route rather than the refusal route
Fatal Flaws
- ! There is no CCF
- ! No specimen submitted with the CCF
- ! No printed collector name AND no collector signature
- ! Specimen ID numbers on the device and CCF do not match (§40.199(b)(5))
- ! Two separate collections performed using one CCF (§40.199(b)(4))
- ! Because of leakage or other causes there is an insufficient amount in the primary specimen and the specimens cannot be re-designated (§40.199(b)(7), §40.83(h))
- ! Seal broken or showing tampering, where the split cannot be re-designated
- ! The collector used an expired device
- ! Expiration date omitted from Step 4 and the lab confirms the device was expired
Training & Documentation
Your qualification as a DOT oral fluid collector is governed by §40.35. Knowledge, device-specific proficiency (5 mock collections per device), and refresher training and the required proficiency demonstration no less frequently than every 5 years (§40.35(e)) — Part 40 uses qualification/refresher language; DOT issues no collector certification.
§40.35 Training Requirements
- aBasic Information — Part 40, Oral Fluid Collection Guidelines, applicable DOT mode rules
- bQualification Training — all steps of oral fluid collection for the device you'll use, problem collections, fatal/correctable flaws
- cInitial Proficiency — 5 consecutive error-free mock collections on the specific device:
- One uneventful collection
- One insufficient specimen quantity (dry mouth) requiring fluid period and second attempt
- One where the employee has something in their mouth that might interfere with the collection
- One where the employee attempts to tamper with the specimen
- One where the employee refuses to sign the CCF
For every one of the five mocks, the collector must check the device’s expiration date, show it to the employee, and record the date on the CCF — and when applying the labels, must not cover the expiration date.
- dSequence — finish (b) + (c) BEFORE any real collection on that device
- eRefresher — every 5 years
- fError Correction — within 30 days, 3 mock collections error-free
- gDocumentation — keep per-device records
Retention
| Record | Period |
|---|---|
| Negative | 1 year |
| Non-negative / refusal | 5 years |
| Collector qualification (per device) | While active |
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 are real compliance failures. Be precise about the consequence though: whether a test is cancelled turns on the §40.199 fatal-flaw and §40.203 correctable-flaw rules, not on every deviation automatically.
Top 10 Oral Fluid Mistakes
- 1Skipping the required rinse after an item is removed, colored saliva, or dry mouth — or skipping the 10-minute wait because "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 §40.72 (procedure) + the device IFU together — §40.35 is your qualification
