About Apex Collection & Diagnostics

Apex Diagnostics provides reliable, professional drug testing and screening support for behavioral health programs, employers, treatment providers, and organizations throughout California. Our mission is simple: make testing easier, faster, and more dependable for the facilities that need it most.

We bring trained technicians directly to your location, helping remove the headache of managing testing in-house. Whether your program needs scheduled on-site testing, mobile collection support, multi-panel drug screening, or responsive service for urgent situations, Apex Diagnostics is built to show up prepared, professional, and ready to work.

Our team focuses on accuracy, confidentiality, consistency, and convenience. We understand that facilities have enough moving parts already — staffing, compliance, client care, documentation, and daily operations. That is why we provide dependable testing support designed to fit into your workflow without creating extra burden or unnecessary cost to your organization.

From physical testing locations to on-site services at approved facilities, programs, workplaces, and other professional settings, Apex Diagnostics is committed to delivering clean execution, reliable scheduling, and high-level service every step of the way.

At Apex, we are not just here to collect samples. We are here to be a trusted testing partner — one that helps your organization operate smoother, stay compliant, and serve your clients with confidence.
