You don't have to be sick to participate in clinical research. There are many studies that need healthy volunteers. Participants who are healthy are often needed to provide information that can be compared with people who have a specific illness or condition. Healthy volunteers are also needed in early clinical research studies to help establish the safety, dosage, and side effects of a new drug or treatment. Your participation as a healthy volunteer is an important part of helping researchers develop new treatments and bringing them to patients around the world.
If you're healthy and decide to participate in clinical research studies, you may receive a physical exam, undergo certain tests (for example blood tests or imaging scans) or answer questions about your health and lifestyle. Clinical trial staff will explain exactly what's involved and will answer any questions you might have.
