Healthy volunteer research involves studying individuals who do not have any medical conditions or illnesses. These volunteers participate in clinical trials or other types of research studies to help researchers understand various aspects of health and disease. The data collected from healthy volunteers can provide valuable insights into normal biological processes, help establish baseline measurements for comparison with diseased populations, and contribute to the development of new treatments and interventions. Participation in healthy volunteer research is typically voluntary and subject to informed consent procedures to ensure the safety and well-being of participants.
