S1-Safety 1st Drug Testing was developed to allow employers to get the most out of their safety programs. Five years ago, S1 was tired of hearing how expensive and time consuming drug testing could be. S1 decided to make that equation easy, so we reduced prices, produced better training, listened to the needs of our clients, and developed ways to make the drug testing process simple. S1-Safety 1st Drug Testing is now one of the most recognized drug testing companies in the country. Our Drug Testing Services were developed to allow employers to get the most out of their safety programs. We listen to you - No gimmicks, if you need something unique for your company just ask. S1-Safety 1st Drug Testing specializes in on site drug testing products (includes hair, urine, and saliva), On-Site Drug Testing (includes hair, urine, and saliva), Department of Transportation Collections, Owner Controlled Insurance Programs, and Walk-In Drug Testing.
