Running a business under federal rules means there's no room for error. DOT drug testing isn't optional — it's the law for safety-sensitive roles in trucking, transit, and beyond. You need testing that follows the regulations exactly, every time. One slip can cost you fines or worse. You deserve a partner who knows the rules and helps you stay on the right side of them.

We come to your worksite across Fresno, Madera, and the surrounding Central Valley. Every DOT test follows federal collection standards from start to finish. That keeps your testing valid and your company protected. Dalesia draws on a real compliance background, so the process is done by the book. Best of all, we come to you — which keeps your drivers and crew working instead of driving to a clinic. You get compliant testing without the downtime.

You don't have to manage this alone. Call us, tell us what your company needs, and we'll set up testing that fits. Whether it's one employee or a full crew, we make it simple. From scheduling to collection, we keep you compliant. Choose Pillar Lab Services and keep your business moving.
