How On-Site Testing Works

The process starts with a simple call or online request. You tell us the test type, the panel, and how many employees need to be tested. From there, our certified professional collectors handle everything else.

On collection day, our team arrives at your worksite with all supplies and documentation in hand. They set up a mobile lab, walk employees through the process, and conduct each collection following strict chain-of-custody protocols, with privacy maintained throughout. Many tests deliver immediate results on-site. When a non-negative result requires confirmation, the sample goes to a certified laboratory partner, and results are typically returned within one to three business days. Final results are delivered confidentially to authorized parties only.

Testing Scenarios We Support

Our on-site testing covers the full range of employer situations where drug and alcohol testing applies:

Pre-employment drug screening: Test candidates before they start, without pulling them away from their onboarding schedule.
Random drug testing programs: We support ongoing random pools and can manage selection and scheduling as part of a full program.
Post-accident testing: When an incident occurs, fast and properly documented testing is essential. We can respond to support urgent post-accident collections.
Reasonable suspicion testing: When supervisors have documented cause, our team can be dispatched with the appropriate protocols in place.
Return-to-duty testing: Required after a violation for DOT-regulated employers, these collections follow federally mandated procedures.
DOT-mandated collections: We conduct DOT drug collections and breath alcohol testing following 49 CFR Part 40 standards for regulated employers.
Large-scale testing events: Job fairs, mass pre-employment screenings, and high-volume hiring events can all be handled through mobile collections.

We support both DOT and non-DOT employers in Los Angeles. If your industry falls under FMCSA, FAA, FTA, FRA, USCG, or PHMSA authority, we conduct collections that meet those specific federal requirements.

California Employer Compliance & On-Site Drug Testing

California’s approach to workplace drug testing places significant weight on employee privacy and fairness. Employers must navigate state law alongside any applicable federal requirements, and the intersection of those two frameworks isn’t always straightforward. Working with an experienced on-site testing company in Los Angeles helps support a sound procedural foundation for your program from the start.

For DOT-regulated employers in the Los Angeles area, including those operating under FMCSA, FAA, FTA, FRA, and PHMSA authority, 49 CFR Part 40 governs the collection and testing process. Those standards define specimen collection procedures, chain-of-custody documentation, laboratory certification requirements, and medical review officer involvement. On-site collections conducted by certified professional collectors help regulated employers meet those procedural requirements without routing employees through an unfamiliar facility.

Reasonable Suspicion & Post-Accident Testing in California

Reasonable suspicion and post-accident testing carry heightened documentation requirements. Supervisors must follow established protocols, and testing must be conducted promptly with full chain-of-custody documentation to preserve the legal defensibility of results. Having a local on-site testing provider that can respond quickly reduces the window between the triggering event and the collection, which matters for both accuracy and compliance.

Non-DOT Employers & Voluntary Drug-Free Workplace Programs

Non-DOT employers in California aren’t required by federal law to implement drug testing, but many do so voluntarily to reduce liability, support workers’ compensation claims, and maintain a safer work environment. Industries including construction, healthcare, manufacturing, and logistics across Los Angeles County commonly run on-site testing programs for exactly these reasons. California employment law shapes how those programs can be structured, particularly around pre-employment testing, random testing rights, and reasonable suspicion standards. A testing partner who can assist with policy creation alongside testing execution helps employers design programs that hold up to scrutiny.
