Reasons for Drug Testing

Substance abuse can take a heavy toll on business today. According to the U.S. Department of Labor, drug abuse in the workplace costs employers approximately $81 billion each year in lost productivity.

We perform more than 9 million drug tests annually and offer our clients a comprehensive range of laboratory and on-site drug tests, services and programs. Common reasons for drug testing include pre-employment, random, reasonable suspicion, post-accident, return-to-duty and follow-up testing. Furthermore, companies and organizations perform specialized drug tests on athletes or employees at risk for steroid abuse and employees in Occupational Safety & Health Administration (OSHA) roles.

Pre-Employment Testing

Substance abuse can compromise the integrity and stability of your workplace. Pre-employment drug testing can help you make confident, informed decisions about current and prospective employees and prevent the hiring of individuals who abuse drugs.

Random Testing

Random testing is a strong deterrent to drug users because it is conducted unannounced. An employer selects, using a random selection process, one or more individuals from all of the employees included in the employer’s workplace drug testing pool to test.

Athletic Testing

Our steroid testing detects more than 20 different anabolic agents and their metabolites commonly used by athletes. We also can test for other performance-enhancing drugs, including stimulants, narcotics, beta-blockers and diuretics.
