What we do & who we are


We have been providing nationwide, affordable, accurate and confidential testing since 1989. The combined experience of our courteous and professional staff allows us to offer excellent and unmatched service. We are able to perform testing without a doctor's order and, if needed, anonymously.

Our client's privacy is extremely important to us. Our staff is trained to ensure that our customer's information is kept private and confidential. We take extra steps to ensure that all information is kept secure and only released to authorized individuals.

We have provided testing services to a wide range of clientele from private individuals and concerned parents to professional athletes and public service workers. We have collected numerous samples for television talk shows and their guests.

For corporations large and small who need testing services for their employees, we offer a wide range of employer specific services. Not only can we offer these services to employers of all sizes but in nearly any industry as well. We can also provide specialized services for federal and state regulated industries such as motor carriers (FMCSA), aviation (FAA), railroad (including MoW) (FRA), transit (FTA), pipeline (PHMSA), and coast guard (USCG) companies. So no matter how big or how small your business is or what your business does, we can help make your workplace a safer place.
