24/7 On-Site & Mobile Drug Testing

For businesses regulated by the Department of Transportation (DOT), maintaining a compliant drug and alcohol testing program is not optional; it’s mandatory. At DATCS, we specialize in DOT drug testing that aligns with federal guidelines under 49 CFR Part 40. From post-accident testing to random, pre-employment, return-to-duty, and follow-up testing, our certified collectors ensure every test is conducted properly with strict chain-of-custody and SAMHSA-certified labs. We offer 24/7 on-site DOT testing to meet the DOT’s required windows (8 hours for alcohol, 32 hours for drugs) and help you avoid penalties while prioritizing safety.

Even if your company isn’t regulated by the DOT, implementing a reliable drug and alcohol testing policy is one of the best ways to minimize risk, reduce liability, and promote a safer work environment. Our non-DOT drug testing solutions are ideal for industries such as construction, healthcare, manufacturing, and retail. DATCS provides mobile and on-site testing for pre-employment, post-incident, random, and reasonable suspicion screenings. We help you create a compliant program customized to your company’s needs, with the flexibility to choose the best testing method: urine, saliva, hair, or nail.

Alcohol testing is time-sensitive and must be handled with care. DATCS offers mobile breath alcohol testing using DOT-approved breathalyzers administered by certified technicians. These Evidential Breath Tests (EBT) are commonly used in DOT-regulated post-accident cases but are equally valuable in any industry where safety is a priority. Breath alcohol tests must be completed within 8 hours of the incident, so we offer 24/7 emergency response. Whether for DOT or non-DOT programs, our on-site alcohol testing ensures accurate results with proper documentation, helping you stay compliant and avoid operational delays.

Urine Testing: Urine drug testing is one of the most commonly used methods in both DOT and non-DOT programs. It detects recent drug use and is ideal for routine screenings, post-accident testing, and return-to-duty protocols. For best results, tests should be administered as soon as possible.

Hair Testing: Hair testing provides a detection window of up to 90 days, making it a powerful tool for identifying long-term or habitual drug use. This non-invasive test is nearly impossible to tamper with, and results are highly accurate. It’s ideal for pre-employment screening or situations where chronic use needs to be ruled out.

Nail Testing: Nail testing offers the longest detection window of any method, revealing drug use that occurred months prior. It’s highly accurate and commonly used in legal, forensic, or extended monitoring scenarios. Although more expensive, it’s an excellent option when a detailed substance history is required.

Saliva Testing: Saliva drug testing is quick, affordable, and doesn’t require a restroom, making it ideal for on-site workplace screenings. It detects very recent drug use (within 24–48 hours), making it a useful tool for pre-shift or random testing. This method is widely used for its convenience and ease of administration.

24/7 mobile testing services offer a comprehensive range of drug and alcohol testing options to accommodate workplace policies and regulatory requirements.

• Urine testing remains the most common method due to its reliability, cost-effectiveness, and regulatory acceptance.
• Breath alcohol testing (BAT) is essential for post-accident and reasonable suspicion cases, using DOT-approved equipment that delivers immediate, legally defensible results.
• Hair testing provides up to a 90-day detection window and is nearly impossible to adulterate, making it valuable for pre-employment and random programs.
• Oral fluid testing is ideal for detecting recent drug use within 24–48 hours and requires no restroom access, streamlining collection in remote or high-mobility environments.
• For an extended history, nail testing offers up to six months of detection.

All tests are administered on-site by trained professionals following strict protocols. This flexibility allows employers to conduct accurate, compliant testing 24/7, with minimal disruption to operations, nationwide.

Response times for mobile drug and alcohol testing can vary depending on location, weather, time of day, and testing needs. Urban and suburban areas typically receive faster service due to higher technician availability, while rural areas may require additional travel time. For DOT post-accident testing, rapid response is essential, not optional. Federal regulations mandate alcohol testing within 8 hours and drug testing within 32 hours. Mobile testing services are built to meet these critical timelines, often guaranteeing arrival within the required window. Companies with established accounts benefit from even faster dispatch, as protocols and site details are already on file, reducing administrative steps and expediting technician deployment.

The cost of on-site 24/7 mobile drug and alcohol testing depends on the number of tests, how quickly service is needed, location, and the type of testing performed. Emergency testing, requested on short notice, is ideal for post-accident or reasonable suspicion scenarios and is designed to meet tight compliance windows with a rapid technician dispatch. Businesses with established accounts or regular testing needs often benefit from priority service and streamlined scheduling. Planned on-site testing is a more efficient option for pre-employment or random testing programs, especially when testing multiple employees in a single visit. The choice of testing method (urine, hair, nail, or oral fluid) also plays a role, with each offering different detection windows and operational benefits. While rural or remote areas may require additional travel time, DATCS helps reduce delays by leveraging a nationwide network of certified collectors, strategically positioned to cover urban and less-accessible regions. Mobile testing offers a convenient, compliant solution that minimizes workplace disruption and avoids the hidden costs of off-site testing.

Many industries require strict compliance with drug and alcohol testing regulations, especially those involving safety-sensitive roles. The transportation sector, regulated by the Department of Transportation (DOT), has the most comprehensive requirements, covering aviation, trucking, rail, maritime, and pipeline operations. Industries such as construction, healthcare, energy, manufacturing, and mining also mandate testing to reduce risk and ensure workplace safety. Government contractors must comply with the Drug-Free Workplace Act, while sectors like defense, aerospace, and nuclear power enforce testing due to national security concerns. Even industries not federally mandated—such as hospitality, retail, education, technology, and financial services—increasingly adopt testing programs due to insurance requirements, state laws, and best practices. Mobile drug and alcohol testing services are critical for helping employers maintain compliance, support 24/7 availability, and avoid disruptions, especially for remote, high-risk, or time-sensitive operations.

Yes, an employee can technically refuse a post-accident drug or alcohol test, but doing so has serious consequences, especially in DOT-regulated industries. Under DOT regulations (49 CFR Part 40), a refusal to test is treated the same as a positive test result, which may result in removal from safety-sensitive duties, required return-to-duty protocols, and other disciplinary actions.
For non-DOT environments, employers should have a clear written policy outlining the consequences of refusal. DATCS helps enforce and document refusals with proper procedures, including collector notes and chain-of-custody details. Our collectors are trained to handle refusals professionally and in compliance with federal and company policies, ensuring your organization stays protected and legally supported.

On-site drug testing, also known as mobile or workplace testing, is performed at your location by certified collectors who come directly to your facility, job site, or accident scene. This approach minimizes downtime, speeds up the testing process, and ensures immediate compliance with post-accident or random testing requirements. It’s ideal for employers who need fast turnaround, DOT compliance, or want to avoid sending employees off-site.
In-lab testing, performed at one of our locations, is a convenient option for pre-employment screenings, scheduled appointments, or when specialized testing panels are required. It’s also a good fit for companies that prefer sending employees off-site during the hiring or return-to-duty process.
Whether you need the speed and convenience of mobile service or the consistency of lab-based testing, DATCS offers both options, so you can choose what works best for your business.
