Trials are federally regulated and follow strict scientific guidelines. Research often involves controlled tests on people to check for safety and efficacy. Safeguards are built into the tests and doctors and other health professionals oversee them. Clinical trials take place at clinics, hospitals, research facilities or doctor s offices. Studies may involve hospitalized patients or outpatients.
Many factors determine a person s eligibility to participate in a clinical trial.
Age, medical history and current medical conditions are the most common criteria. Usually, an individual must meet all of the conditions set by the researchers to be involved. Volunteers for clinical trials should find out as much as possible before consenting to participate. Always check with your health care provider before participating in any clinical trial. The methods used to carry out research will vary from test to test, but there are some procedures common to a majority of trials.
