WHAT IS a healthy normal volunteer?

Someone with no known significant health problems who participates in research to test a new drug, device, or intervention is considered a a "Healthy Volunteer" or "Clinical Research Volunteer."

Participants in research studies include both healthy volunteers and patient volunteers. Healthy volunteers are important in addition to patient volunteers because they provide researchers with crucial data and their health information can be used as a comparison. In some studies, researchers need to compare healthy volunteers with people who have a specific disease or condition. Research with healthy volunteers is designed to develop new knowledge, not to provide direct benefit to study participants.

Why are healthy volunteers needed for CLINICAL research?

There are many reasons.
Healthy volunteers have always played a vital role in medical research. When developing a new technique such as a blood test or imaging device, we need clinical research volunteers to help define what "normal" is.

These volunteers are recruited to serve as controls for patient groups. They are often matched to patients on such characteristics as age, gender, or family relationship. They are then given the same test, procedure, or drug the patient group receives. Investigators learn about the disease process by comparing the patient group to the healthy volunteers.
