Why are healthy volunteers important?

Click on this video to hear a recruiter explain why healthy volunteers are important in clinical trails.

Healthy volunteers have always played an important role in research. Reasons healthy volunteers are important to research include:

  • Provide a comparison for those with illness or disease. This can be to:
    • Compare a group of healthy people to a group of people with a disease or illness
    • Compare someone healthy directly to someone with an illness who has similar characteristics (sex, age, family relationship, etc.)
  • Determine normal results (for example, when testing a new blood test).
  • Learn why some people get a disease and other people do not.
  • Help researchers understand why some medicines work well for some people but do not work well for others.
  • Help people in the future.
