Human testing, also known as clinical trials, involves studying the effects of new treatments, drugs, or medical devices on people. This process helps researchers determine the safety and effectiveness of these innovations before they are approved for widespread use. Participants in these trials may receive the treatment being tested or a placebo, allowing scientists to compare results. Before human testing begins, extensive research is conducted in laboratories and on animals to assess potential risks. Ethical guidelines ensure that participants provide informed consent and are monitored for any adverse effects throughout the study. This careful approach aims to protect the health and rights of individuals involved in the research.
