What type of tests are included in an Occupational Health Program?

Obviously testing is specific to the organization's employee population, but generally includes:
 

• Pre-Employment Testing - Drug/Alcohol, Background Checks, Functional Capacity Exams
• On-Demand Periodic/Random Testing
• Absence Management - Short Term Disability, Return to work Exams
• Post-Employment Testing

Isn't it time to simplify with a single solution!
