Requirements for Participation
You can help researchers learn more about how our genes interact with the environment. We are enrolling participants 8 years of age and older. You only need to donate about 1 tablespoon of blood to help scientists continue this important research.
- Must be 8 years of age or older
- Provide a small blood sample (approximately 1 tablespoon)
- Read and sign an informed consent form (parents will consent on their children’s behalf)
- Provide date of birth, gender, race, and ethnicity
More details can be found on the How to Enroll page.
After you join, you will be contacted every year and asked to update your contact information. Updating or verifying your contact information is easy and can be done online, by mail, or over the telephone.
We also ask for names and telephone numbers of one or two people who do not live with you, but who will always know how to contact you, such as a relative, close friend, or neighbor. This information helps us stay in touch with you for regular updates or to ask you to participate in a follow-up study.
Updating or verifying your contact information each year is very important because it ensures we are able to contact you to participate in voluntary follow-up studies.
