Every test we run, in one list.

This is the complete MDTG service list. If a test is not listed here, call and ask. If we cannot do it on-site, we can usually coordinate it through our nationwide partner network.

Test type · Mobile testing

DOT Testing

Federally mandated Department of Transportation drug and alcohol testing for safety-sensitive employees, performed to federal collection standards.

Test type · Mobile testing

Non-DOT General Workforce Testing

Drug and alcohol testing for general workforce employers who are not under a DOT mandate, run with the same collection discipline as DOT work.

Test type · Mobile testing

Urinalysis Testing

On-site specimen collection that meets federal standards by adhering to the DOT Drug and Alcohol Testing Regulations, 49 CFR Part 40 and 382, applied even for general workforce companies.

Test type · Mobile testing

Hair Follicle Testing

Hair follicle testing provides a longer window of detection than urine-based testing, which makes it a strong fit for pre-employment screening.

Test type · Mobile testing

Alcohol Screening & Confirmation Testing

Breath alcohol screening and confirmation testing using DOT-compliant testing devices, including the confirmation step federal rules require.

Test type · Mobile testing

Oral Fluid Testing

A non-invasive method of detecting substance use, with confidentiality and accuracy maintained across all testing procedures.

Program · On-site testing

Pre-Employment Testing

A candidate must pass the drug and/or alcohol test as a condition of employment. Testing can be performed before an offer is made, after an offer but before the employee starts work, or shortly after the employee begins work with continued employment contingent on a passing result.

Program · On-site testing

Random Testing & Consortium Pools

Employees are chosen on a neutral selection basis without advance notice. MDTG runs company random pools and consortium pools, including an independent driver pool, using a non-biased computerized selection program that protects your company from claims of bias. Weekly, monthly, or quarterly selection cycles can be scheduled.

Program · Company services

Post-Accident Testing

Testing when an employee is involved in an on-the-job accident, vehicular or otherwise, that may have involved human error or may have caused a fatality, serious injury, citation, or property damage. Available 24/7, because accidents do not keep office hours.

Program · Company services

Reasonable Suspicion / Cause Testing

Testing based on an objective, factual, individualized basis, such as observed behavior or physical appearance suggesting drug and/or alcohol use or possession. The suspicion is the documentation of incidents, behavior, and appearance, brought to the employee’s attention.

Program · Company services

Return to Duty / Follow-Up Testing

Periodic testing of employees who return to work after completing an alcohol or other drug rehabilitation program. Follow-up testing helps encourage and confirm that employees remain drug-free after treatment.

DOT or Non-DOT, the process is the same: you call, a certified collector comes to you, specimens are collected to federal standards, and the paperwork is handled for you. MDTG coordinates testing nationwide through partner collectors, so multi-site employers can run one program with one phone number.

02 — Post-accident response

After an accident, the federal clock starts.

DOT rules do not wait for business hours. Under 49 CFR 382.303, a qualifying accident starts fixed testing windows — and a missed window has to be documented, not improvised.

Hour0

The accident happens

A qualifying crash — fatality, injury with immediate treatment away from the scene, or disabling damage with a citation — starts the clock.

Within2 hrs

Alcohol test attempted

The alcohol test must be administered within 2 hours of the accident. If it is not, the employer documents why.

At8 hrs

Alcohol attempts cease

If the alcohol test still has not been administered within 8 hours, attempts stop and the reason goes on record.

Within32 hrs

Drug test collected

The drug test must be collected within 32 hours of the accident. After that, the window closes and the miss is documented.

Testing windows summarised from the DOT post-accident testing rule, 49 CFR 382.303, for DOT-regulated employers. Whether a specific accident triggers testing depends on the circumstances and the citation issued — call and we will walk through it.

03 — Why mobile

Your people stay at work. The testing comes to them.

Sending an employee to a clinic costs you the drive, the wait, and the rest of the shift. A collector at your site finishes most collections in minutes, and a full crew can be tested in a single visit.

Less downtimeNo clinic trips, no waiting rooms, no lost shifts for routine testing.
Defensible paperworkCollections follow 49 CFR Part 40 procedure, with chain of custody documented on every specimen.
One call, any hourPost-accident and reasonable suspicion testing at 2 p.m. or 2 a.m., across the Metroplex.

One program. One phone number. Every shift covered.

MDTG collectors cover the Metroplex directly and coordinate testing nationwide through partner collectors, so a multi-state employer runs one program instead of a dozen vendor lists.

04 — How it works

Four steps, one phone call.

Routine testing can be scheduled ahead. Post-accident and reasonable suspicion testing starts the moment you call.

05 — Client accounts

The programs that run on MDTG.

Airports, freight carriers, manufacturers, tollway operators, and city governments across the Metroplex run their drug and alcohol testing through MDTG today.

Anchor account — DFW International Airport

Every shuttle bus at DFW runs on this program.

MDTG runs drug and alcohol testing for the shuttle bus operations at Dallas Fort Worth International Airport — the remote-lot, employee, and terminal shuttles that move passengers and crews around the airport around the clock.

With roughly 700 drivers and staff in the program and accidents happening every day, that account alone is a standing post-accident and random testing operation — the kind of work that has to be answered at 3 a.m., not queued for the morning.

08 — FAQ

Questions employers ask first.

Do you really answer at night and on weekends?

Yes. MDTG dispatches 24 hours a day, 7 days a week at (214) 280-0101. Post-accident and reasonable suspicion testing often cannot wait until morning, and DOT rules set strict testing windows after an accident.

What is the difference between DOT and Non-DOT testing?

DOT testing is federally mandated for safety-sensitive employees and follows 49 CFR Part 40 collection procedures and Part 382 program rules. Non-DOT testing covers general workforce employers. MDTG applies DOT collection standards even to Non-DOT work, so your program holds up to the stricter standard either way.

How does the random consortium pool work?

Your employees enter a pool, either your company pool or a consortium pool shared with other employers, including an independent driver pool for owner-operators. Selections are made on a neutral basis by a non-biased computerized program, without advance notice, on a weekly, monthly, or quarterly cycle you choose.

Which test should we use: urine, hair, or oral fluid?

Urinalysis is the standard for DOT and most Non-DOT programs. Hair follicle testing gives a longer detection window and suits pre-employment screening. Oral fluid is non-invasive and useful where observed collection matters. Call and we will match the test to the job and the rule you are under.

Can you test outside Dallas–Fort Worth?

Yes. MDTG is based in Irving and covers the DFW Metroplex directly, and coordinates testing nationwide through partner collectors, so a multi-state employer can run one program through one contact.

We have no testing program at all. Where do we start?

Call (214) 280-0101. MDTG will set up a testing program for you, starting with the test types and timing your industry requires, and handle random selections and scheduling from there.
