Why Fresno Clients Trust Pillar Lab Services

Who We Are

A Team Committed to Excellence

Why We Started

Pillar Lab Services began with a problem worth fixing. Getting a drug or DNA test usually meant taking time off, driving across town, and sitting in a crowded waiting room. Dalesia Malcolm knew it didn't have to work that way. With a background in compliance, she understood the rules behind testing and the frustration of getting it done. So she built a mobile service that comes to you instead. The goal was simple: make accurate testing easy to reach for people and companies across Fresno and Madera.

Mobile and Made Local

We do things differently than a walk-in clinic. Pillar Lab Services is woman-owned and fully mobile, so we bring testing right to your home, office, or job site. That saves you a trip and keeps personal matters private. It also helps local employers keep their crews on the clock instead of off running errands. We serve Fresno, Madera, Chowchilla, Merced, and the nearby Central Valley towns. You get accurate drug and DNA testing on your schedule, handled with care and done by the book.

Yes. Pillar Lab Services is fully mobile, so we bring drug and DNA testing directly to your home, office, or job site. We serve Fresno, Madera, Chowchilla, Merced, and nearby cities. Just call to set up a time that works for you.

Yes, the main difference is how the sample is collected and documented. A legal paternity test follows a strict chain-of-custody process, so the results can be used in court. A peace of mind test gives you the same accurate answer but can't be used legally.

Immigration DNA testing proves a biological relationship for USCIS or an embassy. The process uses approved collection and documentation, and samples are coordinated between the people being tested. Results are sent directly to the requesting agency.

Yes. We provide DOT drug testing that follows federal regulations for safety-sensitive roles in trucking, transit, and other regulated industries. We come to your worksite to collect samples.

Turnaround depends on the type of test. Once we collect your sample, it's sent to the lab and you're told when to expect results. We keep you updated through the process.
