DOT Testing Services for Boerne Employers

DOT drug and alcohol testing procedures are governed by 49 CFR Part 40, while the event that triggers a test depends on the applicable transportation agency’s rules. We support employers with testing for safety-sensitive functions, including routine hiring and random-program needs as well as time-sensitive workplace events.

Our confirmed testing support includes:

• Pre-employment testing: Screening before a covered driver begins safety-sensitive work.
• Random testing: Unannounced selections structured for DOT standards or non-DOT company policies.
• Post-accident testing: Collection support after a qualifying workplace or transportation incident.
• Reasonable suspicion testing: Testing after a trained supervisor documents specific signs of possible drug or alcohol use.
• Return-to-duty and follow-up testing: Testing associated with resuming and continuing safety-sensitive responsibilities after a violation.
• Mobile testing: Employer collection services subject to scheduling and service-area confirmation.

Employers can review our information about Federal DOT Drug Testing, DOT Breath Alcohol, and DOT Post Accident. Information about DOT Audit Preparation and DOT Physicals is also available. Contact our team to confirm which services are currently provided through our San Antonio location before sending a driver.

Pre-Employment & Random Testing

Our team can help with pre-employment testing when you’re screening new drivers before they get behind the wheel. FMCSA guidance requires a negative pre-employment controlled-substances result before a covered CDL driver performs regulated driving duties. Employers should identify the applicable agency and employee category before ordering the test.

We also conduct random testing programs that help you maintain a drug- and alcohol-free workplace over time. Random selection can be set up to match DOT standards or to follow your internal company policies. DOT and non-DOT programs aren’t interchangeable, so the order should identify which rules and company procedures apply.

Post-Accident & Reasonable Suspicion Testing

When an incident happens, timing is critical. We provide post-accident testing with after-hours collection availability for urgent needs. Whether a DOT test is required depends on the accident, any injuries or citations, and the rules of the agency governing the driver.

We also perform reasonable suspicion testing when a trained supervisor observes potential impairment on the job, and we offer guidance so these situations are handled consistently. The decision should be based on specific, contemporaneous, articulable observations that the supervisor can describe and document, rather than a general concern or past conduct.

Return-to-Duty & Follow-Up Testing

Return-to-duty and follow-up testing are often part of getting a driver back into a safety-sensitive role after a violation or treatment program. We can structure these tests to support DOT requirements or to fit your company policies in non-DOT settings. A driver subject to DOT rules must complete the applicable return-to-duty process before resuming covered safety-sensitive work.

Follow-up testing can continue after the initial return-to-duty result according to the prescribed testing plan. Throughout each type of test, our collection team follows chain-of-custody procedures to help protect specimen integrity and document its handling.

DOT & Non-DOT Alcohol Testing Options

Alcohol testing can be completed through several methods, but the right method depends on the purpose of the test. Breath testing measures current alcohol concentration and is useful when an employer needs immediate information during an incident or reasonable suspicion situation.

We also provide urine, saliva, hair, nail, and EtG alcohol testing for non-DOT, legal, or monitoring needs. EtG, or ethyl glucuronide, is an alcohol metabolite that can remain detectable beyond the short window measured by a breath test. Hair and nail testing can show longer-term patterns of use rather than current impairment.

DOT employers should confirm that the selected specimen type and procedure are authorized for the specific testing event. Rapid tests can often provide same-day preliminary results, while verified results are typically available within one to three business days depending on the test and laboratory review.

What to Expect at Your DOT Test

When you arrive at our NW San Antonio location, our staff checks your identification and reviews any forms that your employer has provided.

Check-In & ID Verification

Please bring a valid government-issued photo ID, such as a driver’s license or passport. If your employer is sending you, bring any authorization forms or paperwork they give you, along with your ID. For minors who are being tested, a custodial parent or legal guardian must be present with proper identification so we can complete the required documentation.

Private Sample Collection

The collection process itself is structured and private. For urine tests, we’ll ask you to provide a sample with specific instructions on what to do before and after collection. We recommend avoiding excessive fluids right before your appointment, as this can sometimes affect specimen validity. For breath alcohol testing, a team member will guide you through using the device step by step.

Chain of Custody & Result Delivery

Our staff follows chain-of-custody procedures for samples, including labeling, sealing, and documenting each step before sending them to the laboratory when required. For regulated drug testing, result reporting may include review by a Medical Review Officer, a physician responsible for evaluating laboratory findings and relevant medical explanations.

Many rapid tests can provide a preliminary result quickly, and verified laboratory results are typically ready within one to three business days. Timing depends on the test, laboratory review, and whether additional verification is required. Employers should confirm who’s authorized to receive the report and how results should be transmitted.

Arrange testing without guessing about the paperwork or timing. Call us at (210) 361-6497 or contact us online to discuss DOT drug and alcohol testing serving Boerne employers and drivers.
