The screening visit is a key step to joining a clinical trial. At this visit, you will review the informed consent document with members of the study team at the PCRU. The informed consent document describes the details of the clinical trial, including what your rights and responsibilities would be as a participant, and any potential risks, so that you can decide whether you’d like to participate. The study team will answer any questions you may have.If you decide to participate, you will sign the informed consent document and then undergo study-required tests, procedures, or assessments to confirm whether you meet the eligibility criteria for the study. These may include blood tests, an electrocardiogram (a test that uses sensors attached to the skin to check your heart’s rhythm and electrical activity), and vital signs.
