About OnSite Employer Testing
Who We Are
OnSite Employer Testing is a mobile drug and alcohol testing company based in Rolling Meadows, Illinois. We work with employers across the country who need workplace drug testing — but don't want to send their employees to a clinic every time.
We bring certified collectors directly to your location. Whether you have 5 employees or 500, we schedule around your shifts, come to your site, and handle all the paperwork.
We're operated by Youfi, LLC and serve employers in transportation, warehousing, construction, manufacturing, and more.

Why We Started This Company
Most drug testing companies make employers do the hard part — figure out which clinic to use, send employees off-site, and chase down results. We built OnSite Employer Testing to flip that process. You tell us where and when. We show up, do the test, and get out of your way.
What We Believe
- Testing should be easy for HR and fair for employees
- Employers shouldn't lose half a shift sending people to a clinic
- Paperwork and chain of custody should be handled correctly — every time
- Clear communication before and during every visit matters
