What is a Research Participant?
A research participant is someone who chooses to take part in a clinical research study. Participation is entirely voluntary and reflects a personal decision to contribute to the advancement of medical knowledge.
Clinical research relies on people who are willing to help researchers learn more about diseases, how they progress, and how future treatments might be developed. Participants are not receiving standard medical care through a study — they are helping science move forward for the benefit of others.
Before joining, each person is given clear information about the study’s purpose, what participation involves, and any potential risks. This process is called informed consent. It ensures that individuals understand their role and can make a thoughtful decision about whether to participate. Participants can also choose to withdraw at any time.
Some research involves individuals who cannot provide informed consent themselves, such as children or those with certain health conditions. In those cases, a legally authorized representative gives permission on their behalf to ensure ethical participation.
Clinical research would not be possible without people who volunteer. Each participant plays a vital role in helping researchers and physicians discover knowledge that may shape the future of care. Their generosity and willingness to take part represent a quiet but powerful act of service — one that contributes to the well-being of others and the progress of medicine for generations to come.
