On-Site Testing Services in New Braunfels, TX

Certified Collectors Who Come to Your Job Site, Terminal, or Accident Location

When a driver can’t leave a route or a crew is mid-shift, pulling workers off the job for drug or alcohol testing creates real costs. Fastest Labs New Braunfels sends certified collectors directly to your location, keeping your operation running while helping you satisfy compliance requirements. With more than a decade in the industry, we’re equipped to handle the full range of testing needs for New Braunfels employers.

DOT-Compliant Testing Built Around Your Schedule

Our collectors follow all DOT protocols, and our partner laboratories are SAMHSA-certified, so results support regulatory review. Test results are handled with strict confidentiality, and only authorized personnel have access to outcomes. We also offer comprehensive support for alcohol testing programs, from initial policy creation through implementation and any required follow-up actions.

For employers along the I-35 corridor, a compliance delay isn’t just a paperwork problem. Missed testing windows can affect delivery schedules, contract terms, and revenue. We work with transportation companies, construction firms, school districts, and delivery services to design testing schedules that align with routes, shift changes, and peak operational periods.

Our hours, staffing, and communication are structured around employers who can’t afford downtime. On-site testing is particularly effective for larger workforces and during busy seasons when pulling workers off-site simply isn’t practical.

Who We Serve & the DOT Agencies We Cover

DOT testing applies to anyone performing safety-sensitive functions for a regulated employer, including commercial drivers, bus operators, and mechanics. We serve businesses regulated by all six DOT agencies:

FMCSA – Federal Motor Carrier Safety Administration
FAA – Federal Aviation Administration
FTA – Federal Transit Administration
PHMSA – Pipeline and Hazardous Materials Safety Administration
FRA – Federal Railroad Administration
USCG – United States Coast Guard

How the On-Site Testing Process Works

Once a test is scheduled, our certified collector arrives at your location with everything needed to complete the collection. Breathalyzer tests deliver instant results for post-accident situations. For drug and alcohol tests sent to the lab, most negative results are available within 24 to 48 hours. Positive results take longer because they require confirmation by a Medical Review Officer (MRO), an independent physician who verifies results before they’re reported under Department of Transportation regulations.

We walk both employers and employees through every step of the process. For random testing programs and FMCSA Clearinghouse services, we track testing windows, send reminders, and manage required reporting so deadlines don’t slip. If an employee refuses a required test, that refusal is treated the same as a positive result under DOT rules, and specific protocols must be followed. We can guide your team through that situation to help keep your response documented correctly.

Certified Equipment & Technicians for Alcohol Testing

All on-site alcohol testing is performed by certified Breath Alcohol Technicians (BATs) using DOT-approved devices. A BAT has completed a DOT-recognized training and proficiency program for administering breath alcohol tests. On-site collections for DOT-regulated programs typically involve breath alcohol testing and urine drug testing, both of which follow strict chain-of-custody procedures to protect sample integrity from collection through final reporting.

When DOT Alcohol Testing Is Required

The Department of Transportation requires alcohol testing for employees in safety-sensitive roles under several specific circumstances: random selection, reasonable suspicion, post-accident, return-to-duty, and follow-up testing. Pre-employment alcohol testing isn’t mandated by DOT rules, though many employers include it as part of their overall policy. Each scenario carries its own documentation and timing requirements. We help employers understand those obligations before a situation arises, not after.
