Once upon a time Employers and Organizations said they could not afford drug testing. Many felt there was no need. Most agree they can no longer afford to do business without it. Superior Drug Testing (SDT) was founded to help employers identify current and prospective employees who abuse drugs, and direct them to appropriate resources for assistance. As a member of the Drug and Alcohol Testing Industry Association, we subscribe to the highest standards in the business.This website will show you why you should consider testing and how our experience in designing custom tailored programs can improve the safety and productivity of your organization. We also provide a customer service hot line so you can deal directly with our client support staff and to order supplies. SDT can also make an At Home Test system available to you.
