Screening for Any Need

With our DNA and drug screenings, there’s never any room for doubt. We can test for a number of different substances according to your needs. No matter what we are testing for, our team adheres to strict protocols to ensure the results are accurate and defensible.

Two of our most popular services are pre-employment screenings and random drug testing. We work quickly to get the result you need so you can keep your operation moving forward. Furthermore, our staff utilizes all the legal precautions to minimize cheating.

Post-incident drug testing is available for special circumstances. When there is an accident or another event at your workspace, post-incident testing is an effective way to determine if drugs or alcohol may have been a factor.

The Thorough Background Screenings You Need

It’s important to know exactly who you are dealing with. With our thorough background checks, you get all the details available on the person in question. We offer several search options to suit your purposes, handling everything from employment verification to looking for past misdemeanors and felonies. Reach out to our staff to learn more about the screening options available to you.
