Why On-Site Testing Works for Employers

Coordinating off-site testing across large teams or multiple shifts creates real scheduling headaches. On-site testing removes that friction. Our mobile, on-site testing service provides less downtime caused by on-the-job testing, keeping collections at your location rather than pulling workers away for an hour or more.

Our on-site setup also supports chain-of-custody integrity. A shorter time between notification and collection reduces variables that can complicate results. Each collection follows strict chain-of-custody protocols, and our certified professional collectors conduct each test with the same precision and confidentiality you’d find at our facility. Results are often available within minutes on-site, and our DOT-compliant testing services meet federal regulatory requirements for covered employers.

What Our Mobile Lab Setup Looks Like

There’s no special preparation required on your end. Our collectors arrive, set up a mobile lab in your employee bathroom, and get to work. The setup is quick, highly sanitary, and contamination-free. It supports the privacy and comfort of the collection process without disrupting the rest of your workplace.

Our mobile team is trained and certified to the same standards as our in-lab collectors, which means each specimen collected on-site carries the same quality assurance as one collected at our McKinney facility. Sample types available on-site include urinalysis, saliva testing, hair testing, and breathalyzer tests.

On-Site Testing Methods Available

We offer a full range of specimen collection options at your location:

Urine drug testing: The most widely used method and the primary specimen type for DOT-mandated testing under federal regulations. Available for both DOT and non-DOT employers.
Saliva drug testing: Non-invasive and fast, with results suited for reasonable suspicion and post-accident scenarios where detecting recent use is the priority.
Hair testing: Analyzes a small hair sample and provides a detection window of up to 90 days, commonly used in pre-employment programs.
Nail drug testing: Detects drug use over an extended period, making it a practical choice for programs that require a longer detection window than urine or hair can provide.
Breathalyzer and breath alcohol testing: Conducted on-site by our certified collectors for both DOT and non-DOT alcohol testing needs.

Who We Serve in McKinney & Collin County

Our on-site testing service is available to businesses across transportation, construction, healthcare, and other industries, as well as government agencies and schools. If your organization operates under DOT regulations or simply wants a drug-free workplace, we can accommodate your needs.

Our McKinney location serves businesses throughout Collin County, including the Allen area. The region’s continued growth across logistics, construction, and technology means more employers need compliant testing programs that don’t slow their operations down.

DOT Compliance & Program Management

Regulated employers have obligations that go beyond the individual test event. Our on-site testing is DOT-compliant, and we can schedule collections for every required scenario: pre-employment, random, post-accident, reasonable suspicion, and return-to-duty.

We also help employers build and maintain the programs behind those tests. Our services include policy creation, policy implementation, and ongoing program management. Whether you need help enrolling in a random testing consortium, generating random selection pools, or preparing for a DOT audit, we can support your program from the ground up.

Speed and cleanliness aren’t afterthoughts for us. Scheduled clients at our McKinney facility are typically seen in five minutes or less, and we bring that same sense of urgency to every on-site visit.

On-Site Testing Scenarios We Handle

Workplace testing doesn’t follow a single script. Different situations call for different responses, and our mobile service is built to handle all of them.

Pre-employment screening: Test new hires at your worksite before they begin, without requiring them to travel to a facility.
Random testing: Unannounced random drug testing conducted on-site keeps your drug-free workplace policy credible and effective.
Post-accident testing: When a rapid, on-location response is needed, we can be there quickly. DOT post-accident urine collections must happen as soon as practicable, and on-site availability supports that process.
Reasonable suspicion testing: When a supervisor has credible evidence of impairment, our collectors can conduct for-cause testing at your location the same day.
Return-to-duty testing: Employees returning after a positive test can complete required collections on-site before resuming work.

Testing Made Easy

The process is designed to be as simple as possible for your team. Contact Fastest Labs of McKinney to schedule a convenient time for the mobile team to arrive. We’ll provide all materials and instructions in advance, so there’s nothing complicated on your end.

Our certified professional collectors arrive, set up the mobile lab, and conduct collections with strict confidentiality. Chain-of-custody documentation is completed for each specimen. Many on-site results are available within minutes, and lab-based results return within 1 to 2 business days.

Serving McKinney, Allen & Collin County

Fastest Labs of McKinney serves employers throughout McKinney and Collin County, including businesses in Allen and surrounding communities. Our location near US-75 and State Highway 121 makes scheduling mobile visits to area worksites straightforward, whether your operation is in a commercial corridor, an industrial park, or a multi-site facility.

Drug-Free Workplace Program Support

A compliant testing program starts with a written policy. We offer policy creation services to help McKinney employers establish a clear, defensible drug-free workplace policy, along with implementation support to put that policy into practice correctly.

From there, our ongoing program management covers random name generation, testing consortium enrollment, and DOT audit preparation. Whether you’re building a program from scratch or adding on-site capability to an existing one, we can help you design a solution that fits your workforce.

Drug Testing Methods: What Each Option Detects

Choosing the right specimen type depends on what your program needs to accomplish. Here’s how the four primary methods compare:

Urine drug testing: The most widely used method, urine testing screens for a broad panel of substances and detects recent drug use. It’s the primary specimen type for DOT-mandated testing under federal regulations.
Saliva drug testing: Non-invasive and fast, saliva testing detects recent drug use, typically within the past 24 to 48 hours. It’s well-suited for post-accident and for-cause situations where recency of use matters most.
Hair follicle drug testing: A small hair sample reveals drug use over a period of up to 90 days, making this method useful in pre-employment programs where a longer history is relevant.
Nail drug testing: Because nails grow slowly, nail specimens can reflect drug use over several months or more. This method suits programs that require a detection window beyond what hair or urine can provide.

Each specimen type follows strict chain-of-custody procedures from collection through lab analysis to support accurate, legally defensible results.

Alcohol Testing Methods Available On-Site

Alcohol testing serves a different purpose than drug testing and operates on a shorter detection window. Our certified professional collectors are equipped to conduct breath alcohol testing on-site, which measures current alcohol concentration and is the method required by DOT for regulated industries.

We also offer EtG urine testing, which detects alcohol metabolites and can identify alcohol consumption within the past 80 hours, making it useful for extended monitoring programs. Saliva alcohol testing provides a rapid, non-invasive option for on-site reasonable suspicion or post-accident scenarios. All alcohol testing results are handled with the same confidentiality protocols as drug testing results.

DOT On-Site Testing: How It Works for Regulated Employers

Federal DOT regulations under 49 CFR Part 40 govern drug and alcohol testing procedures for safety-sensitive transportation workers. On-site collection by a certified collector can satisfy these requirements when proper procedures are followed, including urine specimen collection with strict chain-of-custody documentation and DOT-approved equipment for breath alcohol testing.

Regulated employers under FMCSA, FAA, FTA, FRA, or PHMSA jurisdiction must maintain active random testing pools and keep testing records available for audit. Random testing rates are set annually by each modal agency, and employers must meet or exceed those rates each calendar year. Employers who use a consortium to manage their random testing pool can satisfy DOT random selection requirements even with a smaller workforce.

Texas Drug-Free Workplace: What McKinney Employers Should Know

Texas does not require private employers to implement drug-free workplace policies. Employers in federally regulated industries, including transportation, aviation, and pipeline, must comply with applicable DOT testing mandates regardless of state law.

Texas employers who voluntarily implement a drug-free workplace program should contact their workers’ compensation insurer directly to ask about available premium credits or discounts. A written policy that defines prohibited conduct, testing circumstances, and consequences for violations is the standard starting point. McKinney businesses operating under Collin County contracts or school district vendor agreements may also be subject to drug-free workplace requirements as a condition of those contracts.
