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.

DNA and Drug Testing, Done Your Way
Legal Paternity DNA Testing
Need results a court will accept? Legal paternity testing follows a strict chain-of-custody process, so your results hold up for custody, child support, and birth certificate cases. We handle the sample collection and proper documentation from start to finish. You get accurate answers you can stand behind.
Peace of Mind (Non-Legal) Paternity Testing
Sometimes you just need to know. This test gives you the same accurate results without the legal paperwork, so it's a faster, simpler option for personal answers. It can't be used in court, but it settles questions at home. We keep the process private and judgment-free.
Grandparentage DNA Testing
When a parent isn't available for testing, grandparents can help confirm a biological relationship. This test compares a child's DNA with a grandparent's to establish family connection. It's a common path for estate, benefit, and personal cases. We walk you through who should test for the clearest result.
Immigration DNA Testing
Immigration cases often ask for proof of a biological relationship. We provide AABB-style collection and documentation that meets the requirements set by USCIS and embassies. The process is coordinated to match what your case needs. You get reliable results sent where they need to go.
Avuncular (Aunt/Uncle) DNA Testing
This test checks whether a child is biologically related to an aunt or uncle. It's useful when a possible parent can't take part in testing. The results help establish family relationships for personal or legal reasons. We explain your options so you pick the right test the first time.
Sibling DNA Testing
Want to know if you share one or both parents with someone? Sibling DNA testing measures how closely two people are related. It's often used when a parent isn't available to test directly. We help you understand the results and what they mean for your family.
DOT Drug Testing
Employers under federal rules need testing that follows DOT regulations exactly. We provide compliant collection for safety-sensitive roles in trucking, transit, and more. The process meets federal standards and keeps your company on the right side of the rules. We come to your site to keep your crew working.
Non-DOT Drug Testing
Running pre-employment, random, or reasonable-suspicion screening? Non-DOT testing lets you set your own panels and policies. It's built for private employers who want a safe, drug-free workplace. We bring the testing to you, so your team spends less time off the clock.

Frequently Asked Questions
Got Questions? We’ve Got Answers!
Do you come to my home or office for testing?
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.
Is a legal paternity test different from a peace of mind test?
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 for custody, child support, or birth certificate matters. A peace of mind test gives you the same accurate answer but can't be used legally. Choose legal if any court or government office is involved.
What's required for an immigration DNA test?
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, even if they're in different locations. Results are sent directly to the requesting agency. Call us and we'll walk you through exactly what your case needs.
Do you do DOT drug testing for my company?
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, which keeps your drivers and crew working instead of driving to a clinic. Call to set up testing for one employee or your whole team.
How fast will I get my results?
Turnaround depends on the type of test, since DNA and drug panels are processed differently. 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 so you're never left guessing. Call us for the timeline on your specific test.
Can grandparents or siblings be tested if a parent isn't available?
Yes. When a parent can't take part, we offer grandparentage, sibling, and avuncular (aunt/uncle) testing to help establish a biological relationship. These tests compare DNA between available family members. They're often used for legal, estate, or personal reasons. We'll help you decide who should test for the clearest result.
What areas do you serve?
We serve Fresno, Madera, Chowchilla, and Merced, plus nearby cities like Clovis, Selma, Sanger, Kerman, Atwater, and Los Banos. Because we're mobile, we cover a wide stretch of the Central Valley. If you're not sure whether you're in range, just call and ask. We'll let you know right away.
How do I schedule a test?
Call us at (559) 668-0793 to book. We'll ask what type of test you need, confirm the details, and set a time to meet you at your home, office, or job site. We're open seven days a week, 8am to 6pm. Same simple process for personal tests and company screening.
