We are your one-stop shop for workplace drug testing in Texas. You can order tests for many substances individually, or choose from our many drug test panels available. Don't see the panel you want? Simply contact us and we'll be happy to assist you.


We ensure that you get accurate drug test results in two main ways.

First, our Texas drug testing labs are always SAMHSA-certified. These labs are held to very strict standards and regulations.

Additionally, all drug test results are verified by a medical review officer (MRO). This is a licensed physician who validates the accuracy of our drug tests. For example, let's say you have an employee test positive, but they're concerned that it was a false-positive triggered by prescription medication.

An MRO can confirm whether or not this is the case.
