Scientific and ethical aspects of human monitoring.

Screening and monitoring activities have their place in the prevention of workplace and environmental disease and injury. Testing, while still relatively nonspecific at this time, can be appropriately used in such prevention activities. Unfortunately, such information can be misused or even put to malevolent purpose, and this complicates the moral and ethical aspects of such testing. With advances in molecular biology, one can anticipate more refined and individualized testing in the future.
