Types of tests in the workplace include:
• Pre-Employment Tests – Employers perform tests on job applicants and make offers of employment based on negative test results.
• Post-Accident Tests – Employers test employees involved in serious accidents or incidents on the job to determine if alcohol or drug abuse was a contributing factor.
• Random Tests – Employers test employees on a random basis; usually, employees are in a safety or security-sensitive occupation.
• Reasonable Suspicion Tests – Employers test employees after observing patterns of possible drug use, symptoms of being under the influence, or an arrest or conviction for substance abuse.
• Treatment Follow-up Tests – Employees who have returned to work after participating in an alcohol or other drug rehabilitation program are tested at random or specific intervals to ensure they are abstaining from substance abuse.

Why test in the workplace? • Fewer accidents • Increased productivity • Healthier employees • Less tardiness and absenteeism • Lower Insurance Premiums • Fewer incidents between employees • Safer streets and highways • Department of Transportation requirement • Required for CDL licensed drivers
