About Us
National Diagnostics Inc. (NDI) is a leading independent employment screening organization for companies with extensive regional or national employee networks.
NDI is now a HireRight company. 
NDI services include Substance Abuse Testing and Medical Surveillance. Founded in 1990, today NDI processes millions of transactions per year and serves over 10,000 clients in all 50 states, Canada, Central and South America, as well as Asia.
With a history of innovation and industry leadership, NDI continually strives to deliver the most cost-effective and thorough programs to its clients.
NDI takes the burden of administering and managing occupational healthcare screening programs from its clients. In-house legal and medical staffs stay current on the latest regulatory changes to ensure compliance at the lowest costs. NDI's proprietary software and technical personnel ensure that clients receive sophisticated reporting and management tools to meet their specific requirements. Working closely with clients, NDI becomes a natural extension of their human resource and safety departments.
"The NDI team does what it says it will do. We originally began to work with NDI to implement a substance abuse testing program in 1995. Within 2 1/2 years, we saw a significant decrease in accidents and turnover in our driver population. Given the high costs associated with recruiting and hiring new drivers, these were significant cost savings. Three years later, we instituted a medical surveillance program because we saw the opportunity to create further efficiencies and have never looked back. Today, we maintain both programs with NDI."
