DOT Testing for Pre-Employment

Our team can help with pre-employment testing when you are screening new drivers before they get behind the wheel. 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 Post-Accident Testing

When an incident happens, timing is critical. We provide post-accident testing with 24/7 access to collection services, so you can meet strict timing expectations and document whether drugs or alcohol were a factor. We also perform reasonable suspicion testing when a trained supervisor observes potential impairment on the job, and we offer clear procedures and guidance so these situations are handled consistently.

Return to Duty and 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. Throughout each type of test, our collection team follows chain of custody procedures to help protect the integrity.

DOT Alcohol Testing Solutions

Alcohol testing can be completed through several different methods, depending on your program design. Breath testing helps identify current impairment and is useful when you need immediate information during an incident or a reasonable suspicion situation. Urine, saliva, hair, and nail testing can identify use over different timeframes, and our team can help you choose the option that fits your policy or legal needs.

For situations where you need a closer view of alcohol consumption patterns, we also provide EtG testing through urine, saliva, or hair. This type of test can detect alcohol use beyond the very short window of a breath test. Our rapid testing options often provide same-day screening results, and most verified lab reports are typically available in one to three business days.

What To Expect At Your DOT Test

Knowing exactly what will happen at your visit makes the process easier for both drivers and safety managers. When you arrive at our NW San Antonio lab, our staff greets you, checks your identification, and reviews any forms that your employer has provided. We work to make check-ins quick and professional so drivers can get back to their schedules.

Check-In with 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 and Comfortable Sample Collection

The collection process itself is structured and private. For urine tests, we will ask you to provide a sample in a secure restroom with specific instructions on what to do before and after collection. To reduce invalid results, we recommend that you avoid drinking excessive fluids right before your appointment. For breath alcohol testing, a trained team member will guide you through using the device in a straightforward, step-by-step manner.

Lab-Analysis and Results Delivery

Our staff follows chain of custody procedures for every sample, which includes labeling, sealing, and documenting each step before sending it to the laboratory when required. This process helps keep results defensible for employers, courts, and regulatory agencies. Many rapid tests provide a preliminary result before you leave, and most verified lab results are usually ready within 24-48 hours, depending on the type of test.

If you are unsure about any part of the process, we encourage you to call us before you arrive. Our team is happy to clarify requirements, confirm what you need to bring, and help you feel prepared for your DOT-related test.
