Why Choose Us

Testing when you need it, where you need it
We know testing doesn't always fit a 9-to-5 schedule. That's why we offer 24/7 mobile and after-hours testing for Columbia, Orangeburg, Sumter, Lexington and surrounding areas. Whether you need a test at our office or a collector at your worksite, we work with you to find a time and place that fits.

Support for employers
Employers rely on us to keep their workplaces safe and compliant. We offer pre-employment, random, reasonable suspicion and post-accident testing, along with DOT Consortium/C/TPA services and custom employer and corporate testing programs. Our team helps you set up a program that works for your company, whether you have five employees or five hundred.

Services for individuals
If you need a drug or alcohol test for work, a hair test, a DNA/paternity test, or fingerprinting and a background check, we make the process clear and straightforward. We'll tell you what to bring, what to expect, and how to schedule, and we'll follow up with pricing and availability.

More than testing
As A1 Business Service Center, we also support small businesses and drivers with services such as medical courier support, trucking authority setup, dispatch and freight brokerage services, business setup, and training and workshops.
