INDUSTRIES WE SERVE

If You Have a Workforce, We Have a Solution.

Precision Lab Express partners with Houston-area businesses across high-risk, compliance-driven industries. We understand the federal regulations, the safety stakes, and the operational pressure you’re under — and we show up ready to handle it.

Trucking & Transportation

DOT compliance isn’t optional in this industry — and neither is speed. We keep your drivers tested, your fleet compliant, and your operation moving.

• FMCSA-compliant drug and alcohol testing

• Random pool and consortium management for owner-operators and fleets

• Pre-employment, post-accident, and return-to-duty testing

• We come to your yard or terminal — no disruption to dispatch

Oil & Gas

Your worksites are high-hazard. Your testing program needs to match. We provide fast, on-site testing that meets both DOT and company policy requirements across upstream, midstream, and downstream operations.

• On-site testing at refineries, plants, and field locations

• Pre-employment screening for contractors and direct hires

• Post-incident response testing

• Discreet, professional collectors experienced in industrial environments

Construction

Job site safety starts before the first tool is picked up. We help general contractors, subcontractors, and project owners maintain a drug-free worksite without pulling crews off the job.

• Pre-employment and random testing for crews of all sizes

• On-site collection at active job sites

• Non-DOT programs customized to your safety policy

• Fast results to keep hiring and onboarding on schedule

Staffing Agencies

You’re placing workers fast — sometimes same day. We help staffing agencies screen candidates quickly and stay compliant with client site requirements without slowing down your placement pipeline.

• High-volume pre-employment testing support

• Flexible scheduling to match your placement speed

• Results delivered to meet client onboarding deadlines

• DOT and non-DOT options available

General Employers

You don’t have to be in a regulated industry to benefit from a strong drug-free workplace program. We work with businesses of all sizes across Houston who want to protect their team, reduce liability, and maintain a safe environment.

• Custom non-DOT testing programs

• Random, pre-employment, and reasonable suspicion testing

• Policy consultation available

• Scalable for small businesses to large employers
