Follow Up Studies

Study Follow-up

Some participants may be invited to participate in follow-up studies. You may be invited to the follow-up study because you have a specific condition or gene of interest, or you may be invited to participate as a control (a person who does not have the condition or gene of interest). The level of involvement in these studies can vary from filling out a questionnaire to giving another blood sample, having a physical examination, or diagnostic tests.

If you are invited to a follow-up study, you will have the study explained to you. You are not required to participate in a follow-up study as all follow up studies are voluntary, therefore, you may choose to participate in some follow-up studies, but not others. We do hope you will participate if asked. Participants just like you are helping us learn more about how genes and the environment interact. If you do agree to participate, you will be asked to sign a consent form for the follow-up study.

Below are a few examples of EPR follow-up studies.
